SELF-CONTAINED COMBINATION POWER PLANT USING STIRLING ENGINE Russian patent published in 2001 - IPC

FIELD: heat power engineering. SUBSTANCE: invention is designed for use as self-contained power generating plants for stationary and moving object for generating electric energy, heat and cold simultaneously. Stirling engine produces useful energy in operation which is converted into electric energy by means of electric generator mounted on one shaft with engine. Engine is cooled by cooling system. Cooling liquid temperature in system is lowered to minimum temperature in cold accumulator of system. High temperature exhaust gases from combustion chamber pass into steam-ejector refrigerating machine along main line. Owing to operation of this machine cold is generated in evaporator and is transmitted through cold carrier main line into cold accumulator. Common external heat supply circuit takes heat from cooling system in heat exchanger and heat of refrigerating machine in condenser, transmitting the heat to consumers. To regulate delivery of heat carrier to condenser bypass line with control valve is provided. EFFECT: increased efficiency of Stirling engine owing to reduction of cooling liquid temperature to minimum temperature, provision of production of electric energy, heat and cold. 2 cl, 1 dwg
