The present invention relates generally to pressurized turbines, and, more specifically, to turbine shrouds and blade designs.
In a gas turbine engine, air is pressurized in a compressor, mixed with fuel in a combustor, and ignited for generating hot combustion gases which flow downstream through one or more turbine stages which extract energy there from. A high pressure turbine (HPT) first receives the combustion gases from the combustor and extracts energy there from for powering the compressor. A low pressure turbine (LPT) follows the HPT for extracting additional energy for providing output energy typically used for powering a fan disposed upstream of the compressor in a typical aircraft gas turbine engine application.
Turbine engines are known in the art and provide for the operation of electrical energy or production of mechanical work for transfer to associated apparatuses. Steam turbines employ the energy of a flowing fluid stream for conversion into mechanical energy. In operation of turbines it is important that the working fluid flow steadily through the turbine and that the transfer of heat through the turbine housing is negligible. The power developed for unit mass flow of fluid corresponds to the measurable difference of components in a fluid property called specific stagnation enthalpy. This fluid property comprises essentially of two parts. Enthalpy is a thermal dynamic property which in steam is a function of pressure and temperature. The second part is the kinetic energy due to motion of the fluid through the turbine. Thus, it can be appreciated that the maintenance of a fluid flow through the turbine is of importance.
Steam turbines are still in various states of evolution. In modern use the density of the steam at turbine entry, especially in multistage turbines, can be significantly greater than that at the exit. To provide responsive blades to such difference and to keep the blade heights of the turbine within practical bounds, it is desirable to divide the fluid flow. Thus, the turbine has been divided into multistage compartments including a high pressure compartment which transmits some of the steam back to the boiler for reheating, an intermediate pressure compartment and, if desired, a low pressure compartment. All compartments have turbine blades therein attached to the turbine shaft. Thus, it is of importance to have an effective blade response to this expanding steam as well as efficient fluid movement from one pressure compartment of the turbine to the other.
Accordingly, Applicant has invented a more efficient turbine by ventilating and regulating the turbine to increase the momentum of the turbine, as well as the control over the pressure to allow more efficient conversion into horse power for an electric generator.
The turbine device is a power converter usable with pressurized sources such as steam, air, and water. Applicant's U.S. Pat. No. 4,411,591 in 1983 was constructed in a similar way. Applicant's work on it was the foundation for the concept of a vertical rotating turbine device. At the present, the improvement concept is to manage pressurized sources listed above, more efficiently by ventilating and regulating the turbine to increase the momentum of the turbine, as well as the control over the pressure to allow more efficient conversion into horse power for an electric generator.
The pressure management allows this conversion, because it allows the device more pressure range from within the unit itself, at the collector blades (26). The regulator blades (28), at the center, keeps the pressure in balance as the centrifugal momentum increases away from center. This allows the turbine to regulate pressure and ventilate for a greater ability to generate power without back pressure of the power source. It also relieves much of the stress on the uni-body construction. The vent ports (30) work at various times to transfer pressure naturally from one compartment to another, greatly increasing the balance of pressure throughout the process within the turbine.
The turbine is intended to be used with any pressurized source, air, fluid, or steam. The power output will increase exponentially to the power input.
The turbine can be used within the automotive industry, in developing an electric vehicle. Any business or industry developing alternative electric sources or individuals wishing to develop a home electric power system.
The current device does not depend upon fossil fuels. It has fewer working parts than most turbines, due to the unibody construction. The device requires little maintenance. This turbine gives consumers more freedom of choice to supply their energy needs at a more affordable cost.
Most types of power generation today require fossil fuel or coal. This pollutes the environment and the sources are limited. Alternatives such as wind turbines are so large they are prohibitly expensive for all but large utilities. This device allows the safe generation of power on an individual scale. There is very little opportunity for fire or explosion using air or water. The device is in a managable size for home or automotive use.
Referring more particularly to the drawings,
The turbine torque shaft (18) is connected to bearing systems (16) left and right sides, and extends outward from the pressure management disc (22).
The turbine compartments are formed by placing together discs to form working units. The discs are cast having a left and right pattern. For example, Ventilated Disc (20) (
ventilation holes (30) work naturally with pressure to help form a balance between compartments as centrifugal momentum is expanding outward from center.
