POWER GENERATING PLANT AND METHOD OF ITS OPERATION Russian patent published in 1999 - IPC

FIELD: heat power engineering; power generating complexes delivering electric and heat energy of preset parameters to consumers. SUBSTANCE: when power generating plant operates at maximum or higher delivery of heat energy to consumer, compressed working medium is directed into heater by-passing heat exchanger-recuperator. Power of heater is increased according to enlarged temperature range of heated working medium. heat exchanger-recuperator is connected at heated side to heat takeoff for technical purpose and/or consumer heat supply. For this purpose at least one circulation heat exchange circuit is used. When power generating plant operates at minimum or reduced delivery of heat energy to consumer, compressed working medium is passed as heated medium through heat exchanger-recuperator. Power rating of heater installed behind heat exchanger-recuperator is reduced according to reduced temperature range of heated working medium. EFFECT: increased efficiency of plant. 7 cl, 12 dwg
