FIELD: heat engineering; various power plants. SUBSTANCE: cooling element of heat exchange apparatus is used as thermal electromagnetic wave radiator 13. Thermal energy outgoing in course of condensation of working medium is used for evaporation of high- pressure condensate through radiant heat exchanger between radiating surface of radiator 13 and absorbing surface of at least one section 16 of high-pressure condensate line. In course of radiant heat exchange, energy of flow of thermal radiation generated by radiating surface of thermal radiator 13 is concentrated in area of above-mentioned absorbing surfaces of sections 16 of high-pressure condensate line. Plant for realization of this method is provided with device for converting the thermal energy of condensation into energy of thermal radiation flux and energy concentration unit. The device for conversion of energy of thermal radiation flux is made in form of thermal electromagnetic wave radiator 13; at least one section of high-pressure condensate line 12 is located inside condenser 10. Surface of thermal electromagnetic wave radiator which is in contact with working medium is used as cooling surface of condenser 10. Radiating surface of thermal radiator 13 embraces sections 16 of high-pressure condensate line 12 located inside condenser 10 forming tight chamber between them where device is located for concentration of energy of thermal radiation flux in area of absorbing surfaces of sections 16 of condensate line 12 embraced by thermal radiator 13. Area of radiating surface of radiator 13 shall exceed the area of surfaces of sections 16 of condensate line 12 which absorb concentrated thermal radiation. EFFECT: enhanced efficiency. 3 cl, 7 dwg |
