High efficiency turbine

Abstract
A turbine system has a turbine that uses an aeromatic hydrocarbon as a working fluid. The turbine discharges the fluid in vapor form against a boundary layer on the inside of a rotor where it condenses as it loses its energy. The outside of the rotor is formed to define chambers which are divided into suction and discharge or pressure cavities by stationary and rotating seals. Apertures connect the boundary layer to the pump chambers and apertures are positioned as discharge ports so that as the rotor rotates, it also pumps the working fluid into a closed loop system in which it is reheated and reintroduced into the turbine through a nozzle. The fluid is heated by a fluid heater that may be positioned in the interior of the rotor.
Description




BACKGROUND OF THE INVENTION




1. Field




This invention relates to turbines that are powered by a working fluid supplied under pressure through a nozzle.




2. State of the Art




Closed-loop vapor powered turbine systems are well known. While different working fluids may be used in such systems, water or steam has been a typical working fluid and is in wide spread use today as the working fluid in, for example, many naval propulsion systems. Typically, steam is generated in a steam generator such as a boiler or similar device. The steam is supplied under pressure to the turbine and is passed through a nozzle which is directed at turbine blades to cause the turbine to rotate. In turn the turbine extracts energy from the steam and converts it into mechanical energy or rotational torque. As the working fluid (e.g., steam) leaves the turbine, it is typically a low energy steam which cannot easily be recycled. So the steam is condensed in a condenser into a condensate which is a liquid such as water. The condensate is then pumped back to the steam generator where heat is added to cause the condensate to vaporize (add latent heat of vaporization) into a vapor (e.g., steam). The steam is then supplied to the turbine to repeat the cycle. Thus steam systems are sometimes referred to as a closed-loop system and sometime as a closed-loop vapor-liquid system because the steam is supplied as a vapor and then converted back to a liquid all within a closed system. Of course in some cases, the steam is heated further to become superheated steam so that more energy is available to operate the turbine.




The condenser typically has another fluid which passes through to remove the latent heat of condensation and in effect transfer the latent heat of condensation to ambient. Thus, a significant amount of heat energy is lost because it is transferred out of the closed loop system. U.S. Pat. No. 1,137,704 (Drake), U.S. Pat. No. 2,378,740 (Viera) are examples of turbines that were devised for use in closed-loop steam systems. Closed loop systems are in common use today in a wide variety of commercial applications to generate electricity for commercial use by power utilities using steam driven turbines where the steam is created using a fossil fuel or nuclear power.




Closed loop systems are of relatively low efficiency because a notable amount of the energy to heat the fluid to create the steam or similar vapor is not used but rather wasted as it is extracted and removed to ambient by the condenser.




Some turbines or cylindrical devices may also be caused to rotate by directing a fluid such as a liquid under pressure against a rotatable drum-like device. See U.S. Pat. No. 509,644 (Bardsley); U.S. Pat. No. 4,390,102 (Studhalter, et al.). The energy available from liquids under pressure is relatively low.




Systems too that seek to extract energy from both a vapor and a liquid are known. See U.S. Pat. No. 5,385,446 (Hays). However Hays teaches one to use a different structure to extract the energy from the liquid and the vapor. That is, the working fluid of Hays appears to have a portion that is in the vapor stage and a portion that is in the liquid stage.




No system as been identified to applicant in which a working fluid is directed at a rotor to extract all energy in whatever form, be it vapor, liquid or a combination of vapor and liquid and to eliminate a condenser and pump the working fluid directly back into a vapor generator. That is, no system has been identified that employs a fluid drag principal for a working fluid that is a vapor or a combination of liquid and vapor.




SUMMARY OF THE INVENTION




A turbine system has turbine with a source of working fluid injected through a nozzle to urge a rotor to rotate in housing. The housing has a housing interior surface and a housing exterior surface with a first aperture formed to extend between the housing interior surface and the housing exterior surface. The first aperture is sized to communicate working fluid in liquid form from the housing interior surface to the housing exterior surface.




A rotor is mounted to rotate within the housing. The rotor has a rotor interior surface and a rotor exterior surface with a second aperture formed to extend between the rotor interior surface and the rotor exterior surface. The second aperture is sized to communicate working fluid in liquid form from the interior surface to the exterior surface.




The nozzle means is connected to receive the working fluid from the source of working fluid and is positioned to direct the working fluid relative to the rotor to urge the rotor to rotate relative to the housing. The turbine also has pump means positioned or formed between the housing interior surface and the rotor exterior surface for pumping the working fluid through the first aperture to exterior the housing.




In a preferred arrangement, the pump means includes seal means positioned between the housing interior surface and the rotor exterior surface to effect a seal there between to inhibit the passage of working fluid there past. The pump means desirably includes at least one chamber formed by the seal means, by a portion of the exterior surface of the rotor and by a portion of said interior surface of the housing. Rotation of the rotor positively pumps the working fluid received from the second aperture through the first aperture to exterior the housing.




Desirably, the turbine system has a discharge with an inlet connected to the first aperture to receive the working fluid therefrom and a outlet connected to the source of working fluid to supply the working fluid thereto. Preferably the source of working fluid includes heat means for heating the working fluid to a desired temperature and preferably the vapor temperature of the working fluid.




In a preferred arrangement, the turbine has flow control means interconnected in the discharge to control the flow of working fluid from the heat means to a vapor generator.




In a more preferred or alternate arrangement, the turbine system has throttle means interconnected in the discharge to regulate the flow through use or operator means for operation by an operator to supply signals reflective of a desired flow.




The turbine system may also desirably have a cooling circuit connected to receive a portion of the working fluid from the discharge. The cooling circuit is operable to cool a portion of the working fluid to a desired temperature a preselected amount below the temperature at which vaporization would occur at the pressure inside of the rotor. The cooling circuit includes a cool liquid supply connected to inject the working fluid cooled in the cooling circuit into the rotor.




The turbine system may also have and preferably does have deaerating means connected to communicate with the rotor interior to remove gases from the rotor interior.




The turbine system is preferably configured to extract mechanical energy from the working fluid by causing the working fluid to be directed at a fluid layer on the interior of the drum when it is rotating. The drag on the boundary layers is sufficient to transfer the energy from the working fluid to the rotor itself. As the working fluid is injected, it cools and the boundary layer increases. The second aperture and preferably a third aperture formed in the rotor are sized to communicate the working fluid in liquid form at the operating pressure in the interior of the rotor from the rotor interior to outside the rotor.




To urge the working fluid into the discharge a pump is provided. Preferably the pump here is the rotor itself which is shaped to function as a pump when combined with selected seals. The rotor exterior surface is formed with a first and second arcuate section each having a first effective radius which extends between the rotor axis and the rotor exterior surface. The rotor exterior surface also has third and fourth arcuate sections formed to have a second effective radius larger than the first effective radius. The third and fourth arcuate sections are interspaced between and unitarily formed with the first and second arcuate sections so that a section with a first effective radius alternates with a section having a second effective radius. The pump therefor has a first chamber formed by seal means, the interior surface of the housing and the third arcuate section and a second chamber formed by the seal means, the interior surface of the housing and the fourth arcuate section. The second aperture is positioned along the perimeter of the rotor to be in communication with the first chamber; and the third aperture is positioned along the rotor perimeter to be in communication with the second chamber. The seal means preferably includes a first seal positioned between the first arcuate section and the housing interior surface and a second seal positioned between the second arcuate section and the housing interior surface.




In a more preferred arrangement, the rotor is formed with arcuate sections to define a third chamber of the pump. Preferably, a plurality of stationary seals are each spaced from the other and mounted to the housing interior surface to extend away therefrom to contact said rotor exterior surface to divide each chamber of said pump into an inlet portion and an outlet portion as the rotor rotates.




Most preferably the rotor interior surface is cylindrical in shape and defines a rotor interior, and wherein said source of working fluid is positioned within said rotor.




In preferred arrangements, the source of working fluid is sized and configured to supply the working fluid at a selected temperature and pressure and flow rate to create a working fluid layer along the rotor interior surface at a desired vapor pressure of working fluid in the interior of the rotor.




In some desired configurations, the throttle means includes a regulator connected to the discharge to receive the working fluid. The regulator is operable between a first position in which no working fluid passes therethrough and a second position in which working fluid passes therethrough. The regulator having operation means such as a handle for operation by a user to operate the regulator between the first position and the second position. Most preferably the regulator is a valve.




The source of working fluid preferably includes a supply line interconnected between the heat means and the vapor generator to communicate the working fluid from the heat means to the vapor generator. The source of working fluid also desirably includes a flow control module connected in the supply line to receive working fluid from the heat means and to supply working fluid to the vapor generator. The flow control module operates to regulate the flow rate of working fluid. More preferably, the flow control module includes a sensing line connected to the discharge to receive working fluid from the discharge. The flow control module has a flow control valve connected to the sensing line to receive the working fluid therefrom and connected to said supply line to regulate the flow of working fluid therethrough. The flow control valve is operable between a closed position inhibiting the flow of the working fluid through the supply line and an open position in which the working fluid passes through the supply line to the vapor generator. The flow control module also desirable includes a pilot valve connected to the supply line to sense the pressure of the working fluid in the supply line and to send signals to said flow control valve reflective thereof. In highly preferred arrangements, the sensing line has damper means interconnected operable to dampen pressure variations in the sensing line.




In desired arrangements, the turbine system has bearings positioned to support said rotor. The working fluid is selected to be of the class that in liquid form may function as a lubricant. Thus bearing fluid means is desirably connected to the injection line in the cooling loop to receive working fluid in liquid form and to the rotor bearings to supply the working fluid as a lubricant.




In alternate arrangements the heat means includes a casing and a plurality of gas plates and a plurality of fluid plates in alternating arrangement positioned within the casing. Each of the fluid plates and each of the gas plates has a central aperture formed therein to together define a combustion chamber. Fuel source means is positioned to supply fuel to the combustion chamber. Air source means are positioned to supply air to the combustion chamber. The heat means also includes ignition means for igniting the fuel in the combustion chamber and exhaust means connected to exhaust combustion by products from the combustion chamber.




Each of said fluid plates preferably has a channel formed thereon with an inlet connected to receive the working fluid and with an outlet in communication with the vapor generator. Each of the gas plates has a plurality of heat transfer nodules positioned thereon.




Preferably, the exhaust means includes an exhaust heat exchanger connected to preheat air being supplied to the combustion chamber. More preferably the heat means includes a first catalytic converter positioned in said combustion chamber to define a first combustion zone to enhance the combustion of the fuel. The heat means may also include a second catalytic converter positioned in the combustion chamber and spaced from the first catalytic converter to define a second combustion zone between said first catalytic converter and said second catalytic converter. The second catalytic converter also functions to enhance the combustion process.




In preferred arrangements, the working fluid is an aromatic hydrocarbon and more preferably diethel benzine.

DESCRIPTION OF ILLUSTRATED EMBODIMENTS




The turbine system


10


shown in

FIG. 1

includes a turbine


12


connected to a discharge


14


and a throttle system


16


. The discharge


14


supplies a working fluid


18


to a source of working fluid


20


which heats the working fluid


18


and returns it to the turbine


12


. Thus the turbine system


10


is a closed loop system because the working fluid discharged by the turbine


12


is processed and returned to it. Except for leakage and other normal losses the amount of working fluid in the system remains essentially constant. Of course given the expansion and contraction of the fluid


18


for different power levels, a system to deal with expansion and contraction of the fluid volume is included and is discussed more fully hereinafter.




In

FIG. 1

, the discharge


14


includes a line


22


that is connected to the turbine


12


at its outlet


23


to receive working fluid


18


being discharged by an operating turbine


12


. The line


22


may be any suitable pipe or conduit sized to transmit the volume of working fluid for the desired power levels of operation and also withstand the temperature and pressure selected for the turbine system


10


with appropriate safety margins selected by the user.




The line


22


is shown in

FIG. 1

supplying the working fluid


18


to an engine brake valve


24


that is optional. The engine brake valve


24


is any suitable valve that is manually operable by a handle or electrically operable such as a solenoid valve. The engine brake valve


24


is operable between a full open (no braking) and a closed position (maximum braking). In the full open position, the flow of working fluid is unimpeded so that the turbine system is fully operable. In the fully closed position, the flow of working fluid is stopped so that the source of working fluid is no longer able to process and supply working fluid


18


. In turn the turbine


12


begins to slow with the build up of fluid


18


therein. At intermediate positions some limited braking may be induced depending on the system selected.




A safety valve or relief valve


26


is also shown connected to the discharge line


22


and is set to operate to relieve an over pressure condition and thereby preserve the integrity of the turbine system. An over pressure condition could arise upon malfunction of the source of working fluid


20


.




The discharge line


22


is next connected to a flow divider


28


which receives the incoming working fluid


18


and divides it with some flowing into a cooling system


30


which is discussed hereinafter. The majority of the incoming working fluid


18


is directed toward the fluid heater


32


via line


34


. The flow divider


28


may be a valve-like device that is operable to divide the flow from about


50





50


to about


90


-


10


. The flow divider


28


may also be fixed orifices or restrictors selected to divide the flow as desired for operating flow rates at given pressures and temperatures. Of course any device may be selected as desired to effect a flow division which is preferred to be from about


70


-


30


to about


80


-


20


with the smaller flow being directed toward the cooling system.




The throttle system


16


is here shown to include a throttle valve


36


connected to line


34


by line


38


to received working fluid


18


therefrom and by line


40


to return the fluid to the cooling system


30


. The throttle valve


36


is operable from a fully closed to a fully open position typically by a user operating an associated handle. Of course, the throttle valve


36


may be operated by a motor or by other suitable means from a remote location if so desired. With the throttle valve


36


fully closed, the working fluid


18


proceeds from the flow divider


28


directly to the source


20


and more specifically to the fluid heater


32


. With the throttle valve


36


open, working fluid


18


is diverted from the line


34


through line


38


, the throttle valve


36


itself and the line


40


to the cooling system


30


. Although the diverted fluid


18


A could be returned to a reservoir or make-up-feed tank, it is preferred to return it to the cooling system


30


because at low power rates, the flow in the cooling system


30


needs to be supplemented as does the flow through the lubrication system


42


. A separate make-up or supply line


39


is also shown so that additional working fluid may be added to the system at a location separate from the reservoir which is discussed hereinafter.




After the working fluid


18


is heated in the fluid heater


32


, it proceeds via line


44


to a flow control module


45


and specifically to flow control valve


46


. The flow control valve


46


operates between open and closed positions to regulate the flow rate of working fluid being supplied to a vapor generator


48


and in turn to the turbine


12


. A sensing line


50


is connected to line


34


to supply working fluid


18


through an optional pulse damper


52


and through restrictors


54


,


56


and


58


to the flow control module


45


. The restrictor


54


supplies working fluid to a balance end


60


of the flow control valve


46


and to a pressure regulator


62


. The pressure regulator of the flow control module


45


is set to maintain the pressure in the balance line


64


at about 175 pounds per square inch absolute (psia). The restrictors


56


and


58


supply working fluid


18


to opposite sides of a balance plate


66


that is attached to and that moves with a valve shaft


68


. The working fluid is supplied to opposite chambers


70


and


72


with the pressure of the fluid in the chambers


70


and


72


acting on the plate


66


. When a user wants to increase the power output of the turbine


12


, the fluid heater


32


is operated as discussed hereafter to cause the temperature of the working fluid exiting the fluid heater


32


to be hotter and at a higher pressure. The pressure of the working fluid


18


acting on the piston


74


of pilot valve


76


causes the piston


74


to move overcoming the pressure on the balance end


78


thereby allowing the upper ring


80


to unblock or open the orifice


82


and causing the lower ring


84


to block its associated orifice


86


. In turn the pressure of the working fluid in the chamber


70


decreases so that a pressure differential now exists between the fluids in the chambers


70


and


72


. In turn the valve shaft moves toward the open position with the force on the balance end


60


being selected to regulate the rate or degree of movement of the valve shaft


68


. Of course, system operation that leads to a lower temperature or pressure of fluid in line


44


causes the piston


74


of the pilot valve


76


to move to block orifice


82


and to unblock orifice


86


to cause the pressure in the chambers


70


and


72


to in turn cause the valve shaft


68


to move to reduce the flow toward the inlet to the turbine


12


.




In

FIG. 1

, it can be seen that the flow control module


45


has at least one and preferably two pressure safety valves


88


and


90


which are here shown relieving to a waste location or overboard. Alternately, the valves


88


and


90


could each have a discharge


92


and


94


connected to a reservoir or make-up feed tank to save the working fluid being diverted.




The flow control module


45


may also have a deaeration line


96


connected to the line


44


to supply some working fluid through an optional flow restrictor


98


to a deaerator jet pump or an eductor


100


. The jet pump


100


has a suction line


102


connected to the turbine


12


to extract gases that may collect in the turbine


12


over time. The working fluid


18


C from the jet pump


100


is supplied via through a recovery line


104


and a check valve


106


to reservoir


108


. The reservoir


108


may be positioned to impose a standing head (of pressure) on the system and is sized to be ample to make up for the expansion and contraction of the working fluid at different power levels. It is preferably sized to contain about 1.5 times the volume of working fluid


18


required for the entire turbine system


10


and is maintained about half full. The reservoir


108


also has a vent


110


so that unwanted gases collected by the jet pump


100


may exhaust. The reservoir


108


has a drain


112


so that the reservoir


108


may be drained if desired. The reservoir


108


has a make-up line


114


connected to supply working fluid


18


to maintain a desired volume of working fluid


18


in the turbine system


10


.




The cooling system


30


shown in

FIG. 1

receives working fluid


18


from the flow divider


28


via divider line


116


. A heat exchanger


118


is connected to receive the working fluid


18


and cool it to a desired temperature. The heat exchanger


118


may be any suitable device that is configured to transfer heat to another medium. It is within contemplation that a cross flow radiator type device may be entirely suitable. However other configurations may be selected.




A thermostatically controlled mixing valve


120


is connected to receive the output of the heat exchanger


118


and to a bypass line


122


so that it can mix working fluid from the inlet side of the heat exchanger


118


and the outlet side of the heat exchanger


118


to supply the cooled working fluid


18


D in a cooling line


124


through a pressure regulator


126


to the turbine


12


.




The cooled working fluid


18


D is injected into the turbine


12


proximate the fluid outlet


23


to lower the temperature of the exiting working fluid so that it does not flash as pressure changes occur during the pumping cycles of the turbine pump which is described hereinafter.




In

FIG. 1

, a lubrication system is shown in which cooled working fluid


18


D is received in a lubrication line


128


and directed through a filter


130


which is here shown to be a 10 micron filter. Any suitable filter may be used as desired by the user. A bypass valve


132


and pressure relief valve


129


is shown connected so that if the filter


130


becomes blocked, clogged or otherwise acts to inhibit the flow of cooled working fluid, then it opens (e.g., at a differential pressure of 50 psi). Alternately, the bypass valve


132


may be manually operated to divert working fluid around the filter


130


.




The cooled working fluid


18


D is supplied from the filter to restrictors


134


and


136


which in turn are connected to supply the working fluid to the bearings that support the turbine


12


and also function as the seals for the turbine


12


.




It is presently understood that the cooling system is desirable but not necessary particularly when the turbine of a system is being operated at a higher power level (e.g., above about 30%). Thus, a valve


138


that may be manually operated or operated by a solenoid may be provided in the cooling line


124


to stop the cooling flow from the heat exchanger


118


to the turbine


12


while still providing for lubrication of the bearings


140


and flow to seals


142


as desired.




Turning to

FIG. 2

, a turbine


150


suitable for use as turbine


12


is depicted. A housing


152


has an outside surface


154


and an inside surface


156


. Three apertures


158


,


159


and


160


are formed in the housing


152


to extend from the inside surface


156


to the outside surface


154


. The


158


-


160


are each sized for the passage of working fluid


18


(see

FIG. 1

) to the outlet


162


of the turbine


150


. As here shown, the outlet is a series of lines show in phantom connecting the apertures


158


-


160


together and directing the working fluid into a discharge line


164


.




The rotor


166


is here shown to have an inside surface


168


and an outside surface


170


. The inside surface


168


is cylindrical in shape while the outside surface


170


is formed to have what is here termed to be several arcuate sections as hereinafter described. Specifically, the rotor outside surface


170


has a first arcuate section


172


which has a first effective radius


174


which extends from the rotor axis


176


to the outside surface


170


. The radius


174


is described as an effective radius because the radius


175


of the first section changes from the one point


180


where it is the shortest. That is, the shortest radius of curvature


175


occurs between that point


180


and the axis


176


and is where the outside surface


170


is closest to the inside surface


156


of the housing


152


. The radius of curvature on either side of that point


180


, like radius


174


, is larger and continues to increase the farther arcuately away one moves along the perimeter of outside surface


170


from the point


180


. The first section


172


thus blends or extends into and is unitarily formed with a second section


178


in which the radius of curvature


182


is at its greatest and spaced a distance


182


from the rotor axis


176


. The radius of curvature then continues to decrease until the second section


178


blends into and is unitarily formed with a third section


185


and the radius


188


is again at its smallest which is the radius at point


186


. Again the radius increases to the radius


190


which is equal to the radius


182


for a fourth section


192


. A fifth section


194


and a sixth section


196


are similarly formed with a short radius


198


and a long radius of curvature


200


equal to radius


188


and


190


respectively. Thus, it can be seen that the rotor


166


is formed with a wall thickness


202


that varies in a pattern from thick to thin with the thinnest portions each spaced 120 degrees radially from each other about the perimeter


204


of the rotor


166


. Thus, three chambers


206


,


207


and


208


are formed defined by the inside surface


156


of the housing


152


, the outside surface


170


of the rotor and three rotating seals


210


,


211


and


212


.




The three rotating seals


210


-


212


are attached to and positioned in their respective grooves


214


,


215


and


216


formed in the rotor


166


. The rotating seals


210


-


212


are sized to snugly fit against the inside surface


156


while being made of material that is slidable over the inside surface


156


particularly when the working fluid (e.g., working fluid


18


) is selected to have lubricating qualities. The three seals


210


-


212


are each spaced 120 degrees radially from the others and are located at the points


180


,


186


and


187


where the radii


175


,


188


and


198


are the shortest. The three seals


210


-


212


may be made from any suitable sealing material such as teflon or nylon. However the working fluid, such as working fluid


18


, has lubricating characteristics and so that the seals


210


-


212


may be made of a polished or smooth metal such as steel.




Three stationary seals


218


,


219


and


220


are positioned about the inside surface


156


of the housing and sized to contact the outer surface


170


of the rotor


166


. The seals


218


-


220


are positioned in groves


222


,


223


and


224


and are spring loaded. In turn, the seals


218


-


220


are urged outwardly from their respective grooves


222


-


224


to continuously contact the outer surface


170


. The springs are not shown for clarity but may preferably be leaf springs positioned under each of the seals


218


-


220


along their length parallel to the rotor axis


176


. Alternately, the stationary seals


218


-


220


may be urged outwardly by a plurality of coil springs positioned along the length to cause the stationary seals


218


-


220


to be urged uniformly against the outside surface


170


of the rotor


166


. Alternately, a sponge rubber or closed cell neoprene spring may be used with each of the stationary seals


218


-


220


which are preferably made of polished steel but may be made of any suitable bearing material including teflon and nylon.




The stationary seals


218


-


220


each are positioned 120 degrees radially from each other and act to divide each of the three cavities


206


-


208


into a suction cavity


226


,


227


and


228


and a pressure cavity


230


,


231


and


232


. As the rotor


166


turns clockwise direction


234


, the rotating seals


210


,


211


and


212


pass over stationary seals


218


,


219


and


220


. As the rotating seals


210


-


212


continue to rotate, the chambers


206


-


208


begin to divide into the suction cavities


226


-


228


and the pressure cavities


230


-


232


. That is, the pressure cavities


230


-


232


are clockwise between the rotating seals


210


-


212


and the stationary seals


218


-


220


and become smaller in volume as the rotor


166


turns clockwise pressing and positively displacing the working fluid in the pressure cavity


230


-


232


out through respective apertures


158


-


160


. Similarly the suction cavities


226


-


228


are becoming increasing larger creating a lower pressure or suction so that working fluid on the inside of the rotor


166


is urged outwardly through respective apertures


236


,


237


and


238


and into the suction cavities


226


,


227


and


228


. Thus, as the rotor


166


rotates clockwise, it can be seen that the three chambers


206


-


208


repeatedly are formed into the suction cavities and pressure cavities to effect a positive pumping action to pump the working fluid from inside the rotor


166


through the outlet


162


to the discharge


164


.




While the rotor


166


here shown has an outer surface


170


formed with varying radii of curvature, it should be understood that a turbine


250


may be constructed such as that depicted in

FIG. 2A

with a housing


252


that is cylindrical and a rotor


254


that is also circular in cross section and an appropriate gap


256


.

FIG. 2A

shows a single rotating seal


258


and a single stationary seal


260


. Any imbalance can be off set by placing a counter weight on the inside surface


262


of the rotor


254


. A pump chamber


264


is defined by the inside surface


266


of the housing


252


, the outside surface


268


of the rotor


254


. The chamber


264


is divided into a suction cavity


270


which is becoming larger (in volume) as the rotating seal


258


rotates in a clockwise direction


259


and a pressure cavity


272


that is becoming smaller urging fluid from the inside of the rotor


254


through aperture


274


and discharged through aperture


276


to a discharge line in an associated discharge system. That is, the turbine


250


of

FIG. 2A

is shown with one chamber


264


.




In

FIG. 2B

, a turbine


275


is shown with a housing


276


and a rotor


278


. The rotor


278


is provided with two rotating seals


280


and


282


comparable to rotating seals


210


-


212


. The housing


276


has two stationary seals


284


and


286


that are comparable to stationary seals


218


-


220


and spring loaded in the same manner. The turbine


274


has two pump chambers


288


and


290


comparable to chambers


206


-


208


. The chambers


288


and


290


are divided into suction and pump cavities the same as the chambers


206


-


208


with the rotor being configured to have 4 sections having different radii of curvature as explained in reference to the chambers


206


-


208


.




From the configurations of

FIGS. 2

,


2


A and


2


B, it may be understood that a turbine may be constructed with one or more chambers each of which is divided into a suction cavity and a discharge cavity by stationary and rotating seals. At present it is believed that turbines may be constructed with as few as one and with many chambers (e.g.,


12


) based on the size of the turbine.




In

FIG. 2

, the outer surface


170


is shown with a varying radius of curvature. It should be understood that the outer surface


170


could be formed to have other shapes or forms including even a portion that is alternating concave and convex. That is, a rotating seal could be mounted along a concave portion with a convex portion clockwise and counter clockwise from the concave portion to form a larger chamber for pumping the working fluid.




In

FIG. 2

, a nozzle


292


is shown positioned in the rotor


166


. A working fluid is discharged by the nozzle


292


in a clockwise direction


294


to contact a boundary layer


298


of working fluid formed on the interior surface


168


of the rotor


166


. The resulting drag induces the rotor


166


to rotate in the clockwise direction


234


and produce useful mechanical energy as further discussed hereinafter. A source of working fluid


298


is also shown in phantom in the interior of the rotor


166


along with a combustion chamber


300


, all as discussed further hereinafter.





FIG. 3

is the turbine of

FIG. 2

without the source of working fluid


299


shown. Rather the working fluid is received from a separate source of working fluid (not shown) and supplied via a line


302


that directs the working fluid out through nozzle


304


. In

FIG. 3

, it can be seen that an end plate


306


is held to the housing


152


by an appropriate number of bolts


308


positioned about the perimeter of the end plate


306


. The rotor


166


is formed with a hub


310


that extends inward from the rotor


166


and connects to an output shaft


311


. The rotor


166


, hub


310


and output shaft


311


are shown to be unitarily formed.




The housing


152


in

FIG. 3

has a bearing support


312


that retains a bearing


314


of any suitable or desired configuration to rotationally support the output shaft


311


. Appropriate seals


316


may be provided separately to seal the working fluid into the turbine. Alternately seals may be formed as part of the bearing


314


. O-ring seals or other mechanical seals including labyrinth seals may be used for selected applications.





FIG. 3

also shows rotor seals


318


and


320


positioned on opposite ends of the rotor


166


to effect a seal and retain the working fluid in the chambers of the pump. The seals


318


and


320


also function as thrust bearings. The rotor


166


inside surface


168


may be formed with a small lips


322


and


324


on either end of the rotor


166


to retain the boundary layer. In given turbines, the boundary layer


296


may be thicker than the height


297


of the small lip shown.





FIGS. 4 and 5

depict an alternate turbine


330


similar in construction to the turbine


150


of

FIGS. 2 and 3

with the source of working fluid


332


within the interior


334


of the rotor


336


. The rotor


336


has rotating seals


338


A-C and fixed seals


340


A-C comparable to the rotating seals


210


-


212


and the stationary seals


218


-


220


of

FIGS. 2 and 3

. The rotor


336


is positioned within a housing


342


to form pump chambers


344


A-C. The source of working fluid


332


is centrally positioned and fixedly secured to the end plate


346


that is secured to the housing


342


by a plurality of bolts


347


. The rotor


336


has an axis


337


and is connected to a hub


348


which is in turn connected to the drive axle


350


that is supported by a bearing


351


. The rotor


336


also has rotor seals


352


and


354


which are comparable to seals


318


and


320


. The rotating seals


338


A-C and stationary seals


340


A-C as well as the rotor seals


352


and


354


may be made of an appropriate metal like polished stainless steel lubricated by the working fluid. The source of working fluid


332


is more specifically detailed in FIG.


6


. The air and fuel supply lines and the exhaust lines


333


are shown in more detail in FIG.


6


.




In reference to

FIG. 6

, a source of working fluid


360


is depicted in schematic form. A combustion unit


362


receives air from an air supply system


364


and fuel from a fuel system through idle injector


366


and main injector


368


. There is an ignition source to ignite the air-fuel mixture in the form of glow plug


370


. Air


372


from the air supply system


364


and fuel from the idle injector


366


and the main injector


368


are mixed and burned in a primary combustion chamber


374


. The combustion gases pass through the primary catalytic converter


376


into a secondary combustion chamber


378


. Additional air is supplied through secondary combustion air ports


380


. The combustion gases


379


then pass through a secondary catalytic converter


382


and a throat


383


into a heat exchange region


384


in which the heat from the combustion gases is transferred to the working fluid. The working fluid then passes through a vapor generator


386


and out a nozzle as discussed hereinafter. The combustion gases are exhausted through an exhaust line


388


and through a regenerator or heat exchanger


390


that preheats the air passing through the air supply system


364


. A discharge damper


392


is provided so that a user may regulate the flow rate of gasses out of the combustion chamber


362


.




The fluid heater


394


illustrated in

FIG. 6

depicts any suitable heat exchanger by which heat from the combustion chamber


362


is transferred to the working fluid


385


. The heat exchanger may be of any suitable type or form but is preferably a cross flow system. However any other suitable system may be used as desired. As shown, the heated working fluid


385


then flows through the flow control module


45


(see

FIG. 1

) and more specifically the flow control valve


46


before it passes into the vapor generator


386


. Optional isolation valves


396


and


398


are also shown in FIG.


6


.




A suitable vapor generator


400


is shown in

FIGS. 7

,


8


and


9


. A cylindrical generator housing


402


contains a plurality of fluid plates


404


,


406


and a plurality of gas plates


408


,


409


and


410


all positioned along the axis


412


of the generator


400


which is typically coaxial with the axis of a turbine in which a combustion chamber and vapor generator are installed. For example, the axis


412


may be coaxial with the axis


176


of turbine


150


of FIG.


2


. The vapor generator


400


here shown has from about 4 to about 8 fluid plates


404


and


406


and a corresponding number of gas plates such as plates


408


-


410


. In some applications, one additional gas plate may be provided. The plates are all positioned in the cylindrical generator housing and alternate in a sandwich fashion generally as shown. It is presently believed the plates


404


,


406


,


408


-


410


are press fit into the cylindrical generator housing


402


and then joined together with the wall


412


of the generator housing


402


by a heat process that results in a weld-like association of the plates and the cylindrical generator housing


402


. Of course the cylindrical generator housing


402


is sized to fit within the rotor of a turbine and thus is sized in relation to the size of the rotor and turbine with which it is associated. An end cap or end plate


413


is positioned over the last or outer most gas plate


408


of the vapor generator and a similar end plate is positioned over the opposite end


414


to provide a sealed interior that is in effect a heat exchanger for transferring heat from the combustion gas to the working fluid


385


.




A fluid plate


404


or plate


406


is shown in FIG.


8


. It has an inlet port


416


which receives the working fluid


385


from the discharge line


22


(

FIG. 1

) and through a flow control valve


45


. The working fluid


385


then passes into a spiral channel


418


that terminates in a throat


420


that discharges through an expansion point


422


and into a vapor passage


424


and from the vapor passage through a nozzle


426


for discharge into the turbine within the rotor directed at the boundary layer. The channel


418


is formed by the indentation formed in the fluid plate


404


and the back surface


411


of the gas plate positioned immediately in front of the fluid plate such as fluid plate


404


. A fluid pressure balance port


428


is provided and connected through to the next fluid plate so that the pressure in the working fluid from fluid plate to fluid plate remains essentially the same. A separate fluid control port


430


is also provided to control the flow to each expansion channel in the interior of the vapor generator


400


. A plurality of exhaust ports


432


are positioned about the outer portion of the vapor generator plates like plate


406


so that combustion gases are supplied through the center channel


434


and along the surface


452


of the gas plate so that the combustion gases may pass outwardly to and enter the exhaust ports


432


and may return for discharge into the exhaust line


388


.




The gas plate such as plate


407


, shown in

FIG. 9

is sized to be substantially the same as the fluid plate


404


. The gas plate


407


has a balance port


438


with a small extension so that it connects with the port


428


. In turn working fluid can pass therein and pass from the channel


418


to another plate like from the channel in plate


406


to the channel in plate


404


. Pressure differentials across the fluid plates are therefor at a minimum. The fluid plate


404


is preferably made of a suitable metal with the groove


418


and the vapor passage


424


both concave indentations made in the surface. As stated, the fluid plate


404


and other fluid plates have a sealed channel formed to be a snug or tight association of the gas plate


407


with the adjoining gas plate. The working fluid flows through the sealed channels


418


and


424


.




The port


440


is also provided to extend through the space between the back side


441


of the fluid plate


404


and connect to the port


430


of the gas plate. The exterior rim has ports


444


that interconnect with the ports


332


to form the exhaust ports or channels along the outside perimeters


446


and


448


. The gas plates like plate


407


have turbulence means which are here shown to be rows of raised buttons


450


of substantially the same type and dimension. As here hown the buttons


450


are small cylindrical extensions which extend up from the surface


452


of the gas plate and are placed in concentric rows extending outwardly from the center. The buttons function to stir the exhaust cases as they pass from the interior


434


outwardly in between adjoining fluid plates and the gas plates like plates


406


and


408


.




Although the vapor generator


400


here shown is sized for positioning in the rotor of a turbine, it is to be understood that a vapor generator may be positioned outside of the rotor and outside of the turbine housing in selected applications.




Turning now to

FIG. 10

, a fuel system


454


is shown with a fuel tank


456


. The tank


456


has a level sensor


458


, a filler cap


460


, a vent


462


and a drain


464


. The fuel proceeds from the tank


456


and through a fuel filter


458


to a gear pump


466


. Fuel proceeds through a filter


468


that has a bypass line


470


and a bypass valve


472


operable to bypass the filter


468


. A separate pressure sensor is also shown so that a user may monitor the pressure drop across the filter


468


and in turn monitor the status of the filter


468


. The fuel is then supplied to the idle nozzle


366


through an idle needle valve or metering valve


476


and a check valve


478


. Fuel is also supplied directly through a check valve


480


to the main injector


368


.





FIG. 10

also shows a low pressure switch


482


connected to send an alarm to a remote location to alert operators that the fuel pressure is low. A glow plug starter relay


484


which operates to activate or close a glow plug relay


486


which in turn causes power to be deliver through relay switch


488


to the glow plug


370


. Also shown are conductors


488


-


489


and


490


separately connectable to a remote controller to regulate fuel flow through the main injector


368


.




An engine control unit


492


is depicted in FIG.


11


. It may be any suitable computer like device configured to operate the turbine. The engine control unit


492


is configured to receive an on-off signal and a start signal via conductors


494


and


496


. Outputs may be provided to instruments


498


, to a data logger


500


and to an alarm panel


502


. Connections are provided to a typical electrical system


504


having a battery


505


, an alternator


507


, and a voltage regulator


506


. An engine interface module


510


is show with connections to receive sensor input as shown here and in FIG.


12


. The Engine Interface Module is also connected to operate the starter


512


. A fuel module


514


is provided to operate the fuel injector


368


and other components of the fuel system while at the same time receiving input from the fuel system filter differential pressure detector


474


.




In operation, it should be understood that a turbine of the type herein described has a rotor


520


as shown partially in

FIG. 13

that rotates at a speed sufficient to retain a boundary layer of working fluid


522


thereagainst. The working fluid


523


is typically exhausting from the nozzle


522


as a vapor which drags across the boundary layer


522


. The drag is sufficient to apply a force through the layer to the rotor


520


and in turn induce rotation. At the same time the speed of the vapor will slow as the kinetic energy is delivered to the boundary layer and at the same time it will thereby start to condense to become a liquid and add to the boundary layer


522


. The level of the boundary layer is maintained by allowing the liquid to be pumped out of the interior by the pumping arrangements hereinbefore discussed. By use of an appropriate working fluid which is any suitable aeromatic hydrocarbon, a temperature and pressure profile can be maintained to cause operation with the boundary layer. Further such a working fluid is preferred because it can lubricate as discussed hereinbefore. A diethel benzine fluid is preferred. Diphenal ethane may also be used.




To start a turbine system


10


such as that disclosed in

FIG. 1

, the turbine


12


may be assumed to be at a stand still or stopped with the interior containing working fluid


18


. In some shut down conditions, the turbine


12


may be deemed to be full of working fluid


18


at ambient temperature and pressure. Electrical power is then turned on or made available to all engine controls by manipulating provided engine controls to supply power as necessary. Specifically electrical power is made available to all engine control systems by placing the Engine ON/OFF Switch in the ON position to supply power via conductor


496


of

FIG. 11

to the engine control unit


492


. Activation of a start button itself supplies power via conductor


494


to start the Engine as hereinafter discussed. Specifically, the start switch of

FIG. 11

initiates an automatic start sequence that has been programed into the engine control unit


492


. The engine control unit


492


sends signals to start or engage the starter


512


via the engine interface module


510


. The starter motor


512


connects to the turbine rotor like rotor


166


(

FIG. 2

) via a suitable clutch and drive train to cause the rotor like rotor


166


to spin at a rate sufficient to develop a centrifugal force within the working fluid contained therein to establishes a stationary boundary layer (

FIG. 13

) as the pump portion of the rotor, like rotor


166


pumps the working fluid out of the interior of the rotor and develops sufficient flow rate.




When the rotor, like rotor


166


, reaches a predetermined speed, the engine control unit


492


sends an electrical signal via the fuel control unit


514


to activate the glowplug


370


(

FIG. 10

) and the fuel heater


365


which heats the fuel to facilitate atomization. After sufficient time has elapsed to allow the glowplug


370


and fuel heater


365


to reach full operating temperature, the engine control unit


492


sends an electrical signal to the fuel control unit


514


to open the start and idle fuel metering valve


476


which allows fuel to flow via the fuel heater


365


to the start/idle fuel nozzle


366


which is then ignited by the glowplug


370


. The engine control unit


492


also activates the fan


363


which draws air from ambient through air filter


361


and supplies the air


372


to the first combustion chamber


374


to begin the combustion process.




After sensing a sufficient temperature rise in the exhaust air via thermocouple probe TC-


1


, the engine control unit


492


sends an electrical signal to the fuel control module to deactivate the glowplug


370


and fuel heater


365


.




The vapor generator will begin to generator working fluid


385


vapor which will flow from the nozzle like nozzle


292


or


304


to impart a rotational force to the rotor like rotor


166


to cause it to increase in speed. When the rotor speed has increased to a predetermined level (e.g. 60% of a minimum operational rotational speed (RPM), the engine control unit


492


sends an electrical signal to the engine interface module


510


to disengage the starter motor


512


. The engine control unit


492


has also activated the other sensors and the fuel pump


466


so that continued operation will proceed until the fuel supply is shut off allowing the turbine to slow down and come to a stop. In the interim, operation of the turbine such as turbine


12


is effected by controlling the fuel supply to the injectors


366


and


368


to in turn control the temperature and volume of the combustion gases heating the working fluid like fluid


385


. In turn the vapor generator supplies fluid at higher temperatures and pressures to change the RPM or the power out of the turbine as desired. The throttle valve


36


is also useful to regulate the flow rate of the working fluid like fluid


18


in FIG.


1


.
