(57) Abstract:

The invention relates to the field of power engineering and energy converters, direct cycle (for example, internal combustion engines, Stirling engines), is intended as a stand-alone power plants for stationary and mobile objects with the simultaneous production of electricity and heat. Technical result achieved - increased efficiency and reduced weight and size characteristics of the power system. During operation of the engine 1 produces useful energy that is converted into electrical energy by a generator 4, which is located on the same shaft with the engine 1. For cooling the engine 1 to the cooling jacket 3 is fed water from the cooling system 8, associated with the system of external heat supply 10 through the heat exchanger 9. Water from water supply line 11 is partially supplied to the steam generator 5 to the crosspiece 13 and partly in the steam-water pump-heater 6. High-pressure steam from the steam generator 5 through line 15 enters the steam-water pump-heater 6, is mixed with water from line 11 to form water with high temperature and pressure. Due to this pressure is the supply of hot water is gecici and energy converters, direct cycle (for example, internal combustion engines, Stirling engines), is intended as a stand-alone power plants for stationary and mobile objects with the simultaneous production of electricity and heat.

Known combination unit on the basis of the Stirling engine with generator on the same shaft, lines, fuel supply and heat exchanger for heating a liquid, through which the high temperature exhaust gases of the Stirling engine, while the heated fluid is conveyed to the external line (Application EPO N 0457399. Abstract journal "the Invention of the world", issue 65, No. 5, 1993, page 13). However, this setting is a complex system of joint cooling of the engine and generator, and it is not intended for generation of steam.

A device power plant comprising an internal combustion engine (ice) with the shaft of the consumer power through the coupling, and the utilization of steam turbine installation with circuit of the working fluid including steam turbine, condenser, feed pump, steam generator, placed in the line of production of high temperature exhaust gases of internal combustion engines (Author's certificate. N 1677360. Bulletin izobreteniya external customers.

A device steam-water pump-heater (EOR) intended for use in various industrial technologies using steam, combining the functions of a heater and pump at the same time. The application of EOR can significantly reduce the power consumption for own needs and to reduce the weight and size characteristics of heat exchangers (Energy Petersburg /newspaper/, N 5, (11), from 25.05.99 year). However, previously the steam-water pump-Modulevel in cogeneration plants has not been applied.

A device cogeneration plants designed for the simultaneous production of electricity and heat, comprising an internal combustion engine with a generator on the same shaft, a supply of fuel, the cooling circuit of the engine, the heating circuit (heating system with heat consumers), a system of heat exchangers which transfer heat engine coolant and high temperature exhaust gas in the heating circuit, and a control Board ("Construction review" //Log//. SPb., N 5 (32), may-June 1999, pp. 16-17). However, this device does not involve the production of steam and use it for sacral obtained by carrying out the invention, is to improve system efficiency by reducing energy consumption for own needs, and reduced weight and size characteristics of the power system as a whole.

To achieve this, the technical result of the Autonomous heating system for the simultaneous production of electricity and heat, comprising a Converter direct cycle (for example, internal combustion engine or a Stirling engine with generator on the same shaft, line, fuel line, heat exchanger-the heat exchanger high temperature exhaust gases of the engine through which the highway passes the exhaust gases of the engine, the cooling system of the engine, connected through the heat exchanger system with external heat supplied by the heat exchanger-heat exchanger widetemperature exhaust gases of the engine, made in the form of steam generator, steam and water pump-heater and heat exchanger-a heat exchanger low-temperature exhaust gases of the engine, and line feed water valve, passing through the heat exchanger-heat exchanger low-temperature exhaust gases of the engine, the steam-water pump-heater, svyazannoye, highway high-pressure steam coming from the steam generator with the steam-pump-heater, and highway hot water systems, and the highway exhaust gases of the engine sequentially passes first through the steam generator, and then through the heat exchanger-heat exchanger low-temperature exhaust gases.

The introduction of the Autonomous power system for the simultaneous production of electricity and heat exchanger utilizing high-temperature exhaust gas of the engine, made in the form of steam generator, steam and water pump-heater and heat-exchanger low-temperature exhaust gases of the engine, as well as tap water, the associated jumper with steam and passing through the heat exchanger-heat exchanger low-temperature gases, and steam-water pump-heater and main hot water system, allows to obtain a new property, such as the ability to use the heat of the engine cooling system for a heat supply of external heat consumers, and residual heat treated gases of the engine for hot water supply, this produces pairs of high level is Birmingham hot water.

The drawing shows an Autonomous heating system for the simultaneous production of electricity and heat.

Autonomous heating system includes Converter direct cycle (for example, internal combustion engine) 1 with highway exhaust gas 2 and the cooling jacket 3, the generator 4, located on the same shaft with the engine 1, the heat exchanger-the heat exchanger high temperature exhaust gas is made in the form of a steam generator 5, the steam-water pump-heater 6, the heat exchanger-heat exchanger low-temperature exhaust gas 7, cooling system 8 of the engine 1 is connected through the heat exchanger 9 with external heat supply 10, a water line 11 and valve 12, a crosspiece 13, connecting line 11 with steam 5 valve 14, a line of high-pressure steam 15 coming from the steam generator 5 to the steam-water pump-heater 6, line 16 hot water systems. For the coolant in the cooling system 8 of the engine 1 includes a pump 17.

Autonomous heating system for the simultaneous production of electricity and heat throu the definition of energy through the generator 4, located on the same shaft with the engine 1. For cooling the engine 1 to the cooling jacket 3 is fed by a pump 17 chilled water cooling system 8. To remove the heat load from the engine 1, the cooling system 8 is connected through the heat exchanger 9 with external heat supply 10. Tap water through the control valve 12, line 11 enters the heat exchanger-heat exchanger low-temperature exhaust gas 7, where the water is heated by the residual heat of low-temperature gases coming from the steam generator 5. Next, a heat-exchanger 7 of the water through the saddle 13 valve 14 enters the steam generator 5 to produce high-pressure steam by heat exchange with high-temperature exhaust gases coming from the engine 1 through line 2, and another part of the water enters the steam-water pump-heater 6, in which the setting of the steam generator 5, line 15 goes high-pressure steam. In the steam and water pump-heater 6 due to the special design and the effect of mixing the two-phase vapor-liquid media pressure, intensive mixing of the steam and water, with the subsequent production of hot water with high t is in hot water. To regulate the flow of water is provided by control valves 12, 14.
