Summary:FIELD: thermal engineering. SUBSTANCE: power plant has boiler 1, fan 2, superheater 3 with built-in conveyer 4, fan 5, turbine 6, condenser 7, working medium Dewar flask 8, pump 9, heat exchanger 10, compressor 11, coolant Dewar flask 12 with evaporator 13, compressor 14, and pump 15. Boiler 1 is filled with cryogenic liquid such as liquid nitrogen by means of pump 9. Fan 2 functions to blow down boiler 1 with atmospheric air. Nitrogen heats up within boiler, evaporates, and goes to superheater 3 which is blown down with atmospheric air by means of fan 5. As soon as working medium is brought to desired temperature and pressure in superheater it is passed to turbine 6 where it works and cools down. Upon leaving the turbine working medium goes to condenser 7 wherein it condenses and runs down to Dewar flask 8; then it is conveyed by pump 9 to boiler 1. Coolant is heated in condenser and passed to evaporator 13. Heat is transferred from coolant by means of compressor 14 which builds up vacuum in evaporator; coolant boils at reducing temperature and exhausted into atmosphere by steam (air). Coolant temperature is reduced in this case to desired value and coolant runs down to Dewar flask 12 wherefrom it is supplied to condenser by means of pump 15. Coolant makeup is effected by means of compressor 11 which takes cold air from flue downstream of fan 2 and feeds it to heat exchanger 10 which is also supplied with overcooled counter-current liquid nitrogen (working medium) from Dewar flask 8. Heat transfer results in air liquefying and cooling down to desired temperature; then air goes to evaporator 13 for further cooling. EFFECT: improved efficiency of heat cycle. 3 cl, 1 dwg
