METHOD OF OPERATION OF HEAT SUPPLY SYSTEM Russian patent published in 2003 - IPC

FIELD: power engineering; thermal power stations. SUBSTANCE: according to proposed method system water heated in heating system heaters of extraction turbine is delivered to consumers. Peak thermal loads in system water are carried by peak heat source. Heating system losses are compensated by feed water which is heated and deaerated under vacuum before delivering heating system. For this purpose heating system water is fed into vacuum deaerator to be used as heating agent. To carry peak thermal loads in system water, heat exchanger is used connected by heating medium pipeline to steam boiler exhaust gas duct, and heating system water to be used as heating agent in vacuum deaerator is taken after said heat exchanger. EFFECT: improved reliability and increased economy of heat supply system. 2 cl, 1 dwg
