Date of commencement of the patent:

The invention relates to the field of energy, in particular to generators of various types of energy, and can be used to heat air, water and generate electricity. The essence of the invention is that thermoelectric modules with the possibility of supplying electric power to the motor of the fan unit and external consumers, a rotor are located in the heat-and-power generator including a housing-heater with a combustion chamber and a water jacket, a fan unit with an engine, a rotor, inlet and outlet air connections, Is provided with plane-parallel disks separated from the combustion chamber by a sealed separating wall with the thermoelectric modules fixed to it and on the horizontal surfaces of the combustion chamber, and heat-removing plates located in the air gaps between the plane-parallel disks are made on the sealing wall on the rotor side. The technical result of the invention is the possibility of obtaining three energy carriers from one generator - hot water, hot air, electricity, improved processability, simplification of start-up, increased environmental friendliness and safety of use.

DESCRIPTION OF THE INVENTION

The invention relates to the field of power engineering and can be used for obtaining simultaneously hot air, hot water and electric power, in energy generators, for operation in the field, in emergency situations and in rescue operations on land and water.

A combined water and air heater is known, which includes a tank, casing, heat insulation, medium heating means, cold water supply and air removal systems and additional water heating means made in the form of a flat element fixed at the junction of the intermediate and inner containers, Of three tanks, external, internal and intermediate, in the form of a truncated cone with a removable smaller base, on which the inner container is fixed, and a larger base of the intermediate container is closed with a lid provided with connections for supply and removal of the medium with an air exhaust system made in the form of a fan with an air duct And installed between the tank and the casing (RF patent No. 2,040,739, 1995, bulletin No. 21).

The known device can not generate electric energy, can be used mainly in stationary conditions and is inconvenient for transportation and operation in the field, it is structurally difficult and not technologically in production.

A preheater is known which comprises a casing provided for the passage of flue gases in the upper part of the exhaust pipe with a boiler installed in its lower part in the form of an annular water jacket surrounding the combustion chamber communicating with the combustion chamber cavity with the burner and connected to the upper part of the jacket by the superheater coil, In the zone above the boiler is divided by a transverse partition with a built-in vertical vertical pipe into the upper and lower compartments, the burner is made in the form of a kerosene with fuel and evaporation tanks, equipped with a water-cooled heat exchanger, and a damper is installed in the exhaust pipe of the casing. The heater is equipped with an expansion water tank fixed to the casing and connected to the water-cooling coil of the kerosene, made in the form of a flat tubular spiral located between the evaporation and fuel tanks of the kerosene (USSR Nos. 992941, 1983, Bulletin No. 4).

The known heater does not provide for simultaneous supply of electricity to the consumer, it is not environmentally friendly, structurally complex and inconvenient to operate, especially when starting up, does not possess the necessary safety of use.

The closest to the claimed solution is a water heating system comprising a housing, a furnace with a burner and a water jacket, a contact chamber, wherein the installation body is provided with a mixing chamber connected to the heating nozzle of the fan and a furnace having a hatch with a plug (as. USSR No. 329353, 1972, bulletin No. 7).

The known installation is structurally complicated and not technologically efficient, it is difficult to use, especially during the start-up period, it is not safe enough, not environmentally friendly and does not involve simultaneous supply of electricity.

The problem solved by the invention is:

- obtaining simultaneously from one generator - three energy carriers - hot water, hot air (with the possibility of transportation through a pipeline) and electricity for lighting;

- Increase of manufacturability of use, simplification of start in work;

- Improved environmental friendliness and safety of use;

- reduction of structural complexity.

The problem is solved by the fact that in a heat and power generator including a heater body with a combustion chamber and a water jacket equipped with burners and an exhaust port, a fan unit with an engine, a rotor, an inlet and an outlet air pipes, thermoelectric modules with the possibility of receiving and supplying electric power To the engine of the fan unit and external consumers, burners for gas fuel are installed, the rotor is provided with plane-parallel disks separated from the combustion chamber by a sealed separating wall, with thermoelectric modules fixed on it and on the horizontal surfaces of the combustion chamber, and on the rotor side on a sealed separating wall Plates located in air gaps between plane-parallel disks.

Comparative analysis with a prototype showed that the claimed device is characterized by the fact that thermoelectric modules are placed in the combustion chamber with the possibility of supplying electric power to the engine of the fan unit and external consumers, burners for gas fuel are installed, the rotor is provided with plane-parallel disks separated from the combustion chamber by a sealed dividing wall. The thermoelectric modules are installed on the sealed separation wall and horizontal surfaces of the combustion chamber; heat-sealing plates located in the air gaps between the plane-parallel disks are made on the sealing side of the rotor on the side of the rotor, so the claimed solution meets the criterion of "novelty".

The analysis of similar technical solutions did not allow us to identify in them the features that differentiate the claimed technical solution from the prototype, which allows us to conclude that the claimed solution meets the "inventive level" criterion.

The invention is explained in the drawings.

THERMAL POWER GENERATOR THERMAL POWER GENERATOR

In Fig. 1 shows a front view, combined with a cut; In Fig. 2 - side view, combined with a cut.

The heat generator comprises a housing-heater 1, a combustion chamber 2, a water jacket 3, gas burners 4, an exhaust pipe 5, a fan unit 6, an engine 7, a rotor 8 with plane-parallel disks 9, an inlet 10 and an outlet 11 air pipes, a sealed separation wall 12, Heat-removable plates 13, thermoelectric modules 14, inlet 15 and outlet 16 of the water jacket.

THERMAL ELECTRIC GENERATOR WORKS AS FOLLOWING:

The water jacket 3 is first filled from the water or capacity supply system through the inlet fitting 15, ignition (not shown) is switched on in advance, and the combustible gas is fed into the ejector gas burners 4, with the initiation of a high temperature in the combustion chamber 2 and the exit of the combustion products of the gas through the exhaust pipe 5 The heating of the thermoelectric modules 14 allows an electric current to be generated for the operation of the engine 7 and the circuit of external consumers, for example, lighting lamps. The motor 7 rotates the rotor 8 with the plane-parallel disks 9, thereby directing air from the environment through the inlet air pipe 10 to the fan unit 6 and after heating through the outlet air pipe 11 to the consumer. The discs 9, when the rotor 8 rotates, capture the air and continue the movement of the air along the heat-removable plates 13 mounted on the sealed separating wall 12 with intensive heat capture transmitted from the combustion chamber 2. The supply of the combustible gas to the burners can be from a portable gas cylinder, Water - both from the water supply system, and from a small portable capacity.

The thermal power generator with its compactness makes it possible to obtain a thermal power of at least 3 kW and a voltage in the 12 V electric circuit, while simultaneously producing separate heat carriers (hot water and hot air flow) can be widely used both in stationary and in field conditions. Simplicity of start-up, safety of use and ecological compatibility allow to operate it without restrictions by a wide range of persons without special preparation.
