FIELD: heat power engineering. ^ SUBSTANCE: according to proposed method, steam from turbine extractions is fed to regenerative high and low pressure heaters in which main condensate, after turbine condenser, and feed water are heated successively, and primary makeup water is delivered to heat supply system makeup water preparation plant and is deaerated in vacuum deaerator. Primary water is heated in lower low-pressure regenerative heater nearest to condenser before heat supply system makeup water preparation plant, and regenerative heating of main condensate of turbine is started in low-pressure heater, second from turbine condenser. ^ EFFECT: increased economy and improved reliability of thermal power station owing to heating of primary water to technologically required temperatures by highly economic low-potential extraction of turbine steam at minimum capital layouts for reconstruction of circuit of thermal power station without fitting special primary water heater. ^ 1 dwg |
