FIELD: heat power engineering.
SUBSTANCE: invention is designed for simultaneous generation of heat and power. According to invention, steam from boiler steam line gets into steam turbine with electric generator fitted on the same shaft. Part of mechanical energy from turbine is used to drive compressor to raise pressure of waste flue gases. Heat carrier of external heat supply system gets into condenser where, owing to heat exchange, water vapors are condensed after getting out of turbine, and heat carrier gets heated. To Transfer heat of flue gases to Stirling engine, its heater is installed in boiler plant smoke stack. Heat of flue gases in converted in Stirling engine into useful mechanical energy transmitted to electric generator to generate power.
EFFECT: possibility of generation of additional energy, reduced cost and improved efficiency of heat power system when transforming steam boiler plant into mini-thermoelectric plant.
