FIELD: power engineering.
SUBSTANCE: invention relates to heat power engineering, particularly, to alternative schemes of heat engines with external heat supply. Hot air thermal power plant includes turbo compressor, check valve, receiver, crane, engine, heat exchanger, heater, at that elements of thermal power plant are connected in series: compressor of turbo compressor, check valve, receiver, crane, engine, chamber for heated medium, turbine compressor turbine, heater and/or chamber for heating medium of heat exchanger. Prior to supply of working medium to engine for its mechanical work, it is compressed in compressor of turbo compressor, working medium used in engine is heated in chamber for heated medium of heat exchanger and supplied to turbine of turbo compressor, where it also performs mechanical work, working medium worked on turbine is directed to heater and/or chamber for heating medium of heat exchanger.
EFFECT: providing engine operation at low temperatures of working medium, fast stop and quick start-up.
