FIELD: power engineering.
SUBSTANCE: invention is intended for autonomous cogeneration of thermal and electric power due to energy contained in fuel and external air. Electric power is generated by a steam thermal power plant with its subsequent transfer to a consumer. Waste heat of power plant and heat of external air is transferred to cooler of heat pump and used for heat generation. For operation of the heat pump, the obtained electric power is used, and heat from the heater of the heat pump is transferred to the consumer. Also disclosed is a version of the proposed method, in which electric power is generated by a generator connected to an internal combustion engine, with subsequent transfer thereof to a consumer. Waste gases of internal combustion engine are supplied to heat-generating circulation circuit, in which in the process of natural or forced convection they are mixed with external air, heat of exhaust gases and heat leaving the internal combustion engine and generator is transferred to the heat pump cooler, and after cooling, the gas mixture is released from the circuit through the exhaust valve, wherein the heat pump is connected to the electric generator.
EFFECT: invention implementation enables to reduce fuel consumption and independence from ambient temperature.
