COGENERATION PLANT WITH INTERNAL COMBUSTION ENGINE AND STIRLING ENGINE Russian patent published in 2012 - IPC F02G1/43 F02G5/04 F25B27/02 

FIELD: engines and pumps.

SUBSTANCE: cogeneration plant includes Stirling engine with electric generator, cooling system of Stirling engine with a pump, combustion chamber of Stirling engine, internal combustion engine with electric generator, its cooling system with a pump, heat pump of absorption type, pump of heat utilisation system and a valve. Heat utilisation system consists of heat utilisation heat exchangers of internal combustion engine and Stirling engine, waste gases and heat exchanger for transfer of heat to consumers. Pump of cooling system of internal combustion engine is connected to utilisation heat exchanger of its heat. Pump of heat utilisation system is in-series connected to heat exchangers of this system and heater of Stirling engine. Waste gases of internal combustion engine are supplied to utilisation heat exchanger of their heat, after which they are supplied to combustion chamber of Stirling engine, which is connected to its heater. To combustion chamber of Stirling engine there supplied is gas from gasifier utilising industrial waste of organic origin. Waste gases are supplied from combustion chamber of Stirling engine to absorption heat pump serving as the air conditioner of the turbine hall. Heat energy generated with the heat pump is supplied to heater of Stirling engine. Cooling system of Stirling engine is connected to the pump of this system and heat utilisation heat exchanger of internal combustion engine.

EFFECT: increasing efficiency and ecological properties of the plant.
