The present invention regards the field of water heating or air conditioning systems. More in detail, it refers to an energy saving and low emission heating system that can be particularly used in gas boilers.
In a heating system, a boiler is an equipment in which the transfer of heat from a fuel undergoing combustion towards a liquid occurs without the boiling thereof occurring. On the contrary, should such equipment cause the change of the state of the water from liquid to aeriform, continuously and under controlled conditions, it is better referred to as vapour generator and it is typically used combined with the turbines for producing electrical energy.
Part of the development of boilers is due to the development of fuels. From wood of the early days, around the 18th century we moved to coal, which remained the main fuel for 150 years; combustion occurred in the fire-box, basically a grid on which the solid fuel was placed in a more or less mechanised manner and from which the ashes were removed, in a more or less mechanised manner too.
In the 20th century coal was gradually replaced by liquid fuels; this meant replacing the fire-box with an apparatus capable of injecting liquid/gaseous oxidising agent mixtures into the combustion chamber. These devices are referred to as burners.
The boiler basically consists of:
Also due to the current regulations in force, striving towards ensuring safety as regards the discharge of combustion products, the market has progressively developed towards the installation of forced draft airtight chamber boilers. In this boiler, combustion occurs in a closed (airtight) chamber with respect to the surrounding environment and this entails the need of drawing oxidising air from the external through special ducts, with the ensuing need of providing the boiler with a fan with the function of drawing external air and for forcing (forced draft) the ejection of the combustion products towards the flue which disperses them. If, on the one hand, this latter type of boiler ensures safety with respect to the channelling of combustion gas into the environments, on the other it gives rise to problems related to the discharge of the combustion products and the relative flue system ducts, which are under pressure and should ensure durability (even over time).
Another type of boiler is represented by a base boiler, which is definitely more cumbersome with respect to the previous one, and generally provided with a high capacity boiling device, which requires considerable space for the positioning thereof, it can be of the open chamber or airtight chamber type. Open chamber boilers are generally installed in a room designated to serve as a thermal power station, while airtight chamber boilers are installed if positioned in a residential unit due to the safety regulations in force. The higher capacity of the boiling device guarantees higher possibility of simultaneous use of several domestic water drawing points. The exchanger of this type of boiler can be made of steel (e.g. in wall-mounted boilers) or cast-iron elements. When it comes to operation in liquid fuel (diesel) or solid fuel (wood or pellets) mode, given the different configuration of the combustion chamber, the structure is generally made of steel with the boiling device incorporated or not incorporated, as a function of the needs of the building.
Over the last years, the demand has sky-rocketed, due to the safety requirements and energy saving needs as well as due to the technological development regarding the control of the combustion and thermal adjustment. Though the market offers a wide range of solutions, there still lacks a convincing solution capable of including the exploitation of the properties of hydrogen. As a matter of fact, this natural element widely available in an enormous amount of molecules, also including the water-based molecule to name one, can be used as fuel gas and it may generate extremely high temperatures, in the order of 2800° C., against the average 1200° C. of the other gases.
Up to date, hydrogen seems to have been taken into account more for the development of innovative vehicle engines, to enhance the efficiency thereof and obtain low (if not zero) emissions of CO2, as observable from patent no US 2016244887 having the title “Hydrolysis system and method for a vehicle engine”. The latter regards an electrolysis system which produces fuel gas consisting of a hydrogen and oxygen mixture through electrolysis. Such fuel gas is then placed at contact with an oxidising gas in an expansion chamber in which the combustion which runs the engine occurs. The problem of this and other patents regarding hydrogen combustion regard the safety of the system or engine. As a matter of fact, a hydrogen and oxygen mixture of this type is highly flammable, the temperature is extremely high to the extent of melting most of the metals and the risk of backfire, with the entailed catastrophic consequences, is high.
Thus, an object of the present invention is to provide a new and innovative heating system capable of exploiting the properties of hydrogen derived from the electrolysis process under entirely safe conditions. A further object of the present patent is to describe a heating system capable of reducing both the consumptions and emissions of C02 with respect to the prior art systems.
An eco-friendly electrolysis heating system is obtained according to the present invention given that it enables low energy consumption and extremely low CO2 emissions.
The system described in detail hereinafter, has the object of using the gaseous hydrogen and oxygen mixture (HH—O) obtained from an electrolytic water dissociation action.
The advantages of the present invention consist in improving the conventional gas combustion process in that the user device 100 of the present system will continue exploiting LPG or methane at a percentage comprised between 20% and 30%, replacing the remaining 70%-80% with the gaseous mixture (HH—O) deriving from the system upstream of the appliance 100. The use of the hydrogen and oxygen mixture advantageously entails high energy saving, thus reducing the operating costs and achieving extremely high thermal efficiency. Additionally, thanks to the combustion of said gaseous mixture, the CO/CO2 emissions drop considerably and this due to the percentage increase of emission of plain water vapour, which is entirely harmless for the environment. In light of the above, the system in question is rightfully considered among the eco-friendly heating systems.
Energy saving is basically a result of the characteristics of hydrogen which, burning, generates extremely high temperatures at around 2,800° C., more than twice the temperatures achieved by the combustion of gases used in similar systems up to now, which averagely burn at about 1,200° C.
A further advantage of the present invention lies in the low installation costs, which would enable a quick spreading of the technology described hereinafter, with immediate benefits to the ecosystem and the economy of the users utilising it. This being due to the fact that the system can also be adapted to existent and operative boilers or to other types of appliances 100 currently running on methane gas or LPG.
More in detail, the essential components of the system according to the present invention are:
Advantageously, the entire system is managed and monitored by at least one control unit 80, even positioned remotely, which has a dedicated microprocessor 90. More in detail, said control unit 80 receives data coming from said pressure sensors 70, from said temperature sensors 75 and from a possible pyrometric sensor 140 which can be advantageously arranged in the combustion chamber 150 of the appliance 100, to monitor the intensity of the flame. Said control unit 80 is also suitable to manage, according to parameters pre-set by a maintenance user, the function of replenishing distilled water (H2O) in the generator 10 through the replenishment duct 14, the electric power of the power supply unit 11, the safety solenoid valve 40 and the motors 55-55′ of the tangential fans 50-50′.
Furthermore, said control unit 80 advantageously monitors the correct operation of any other component of the system, in particular the check valves 60-60′ and the safety filter 65.
In case of an error, malfunction or failure, said control unit 80, is advantageously suitable to enable displaying a message showing the nature of malfunctioning on a special display 81. This display 81 serves as a true communication interface between the control unit 80 and the system maintenance man, who—using it—may also set all operating parameters of each component.
In an embodiment, said control unit 80 is advantageously suitable to be connected to a common electronic device remotely positioned for the communication of possible error, malfunction or failure messages and to enable the switching ON/OFF of the system by entering pre-set safety codes. Advantageously, it will also be provided with a timer suitable to enable a user to set a determined time for automatically switching the system ON/OFF.
The invention will be described hereinafter in at least one preferred embodiment, provided by way of non-limiting example, with reference to the attached figures, wherein:
Now, the present invention will be illustrated purely by way of non-limiting example, with reference to the figures illustrating some embodiments regarding the present inventive concept.
With reference to
The system, suitably dimensioned depending on the capacity of the system, is used for heating the water of the containers in which the chlorophyll function is carried out. As a matter of fact, the water used in the photosynthesis process requires a constant temperature at around 30° C.
The aforementioned system also has a medium or high enthalpy geothermal system for producing the electrical energy required for the photosynthesis of the omega 3 uni-cellular algae. This produced electrical energy falls within the context of lighting installations in which the result of the light spectrum is identified as very close to the solar one. This characteristic benefits the coefficient of efficiency of the chlorophyll function. The artificial lighting and heating of the greenhouses make the plant fully independent.
Furthermore, in the step of transforming the oil for propulsion or for the production of products for the pharmaceutical industry, electrical and thermal energy is also integrated with the CO2 production plant required to complete chlorophyll photosynthesis. Lastly, the integrated system makes the conditioning and energy supply process of the system independent.
Furthermore, thanks to the use of the present invention to obtain the correct heating of the culture water, the emissions are also extensively reduced in that they substantially consist of water vapour.

The system may also be provided with a tank for distilled water (H2O) suitable to replenish the distilled water (H2O) in said generator 10 according to parameters pre-set and managed by said control unit 80.
Depending on the capacity of the system designated to be built and the required safety features the water heating system described up to now can also be designed differently, still falling within the scope of protection of the present patent, by installing:
