FIELD: heat power engineering.
SUBSTANCE: mode of thermal power plant operation implying that full-flow condensate is heated with low pressure heaters and delivered to feedwater deaerator. Then feedwater is heated in high pressure heaters connected by heating medium to regenerative bleed-off of turbine. Steam condensate of high pressure heaters is delivered through condensate line to water-evaporator drum. Steam produced in water-evaporator drum is delivered through steam line as make-up heating agent to feedwater deaerator. Condensate not evaporated in water-evaporator drum is delivered by condensate line as heating agent in vacuum make-up feedwater deaerator. Make-up feedwater prepared in vacuum deaerator is delivered by feed pump through pipeline to full-flow condensate line, eg. the second low pressure heater full-flow condensate downstream.
EFFECT: improved efficiency of thermal power plant operation.
