FIELD: heat power engineering.
SUBSTANCE: proposed thermal power station contains steam turbine with main condensate pipeline connected to higher pressure deaerator, atmospheric deaerator of additional feed water with flash steam outlet and heating agent pipelines. Station s furnished with regulator of dissolved oxygen content in mixed flow of main condensate and additional feed water. Said regulator is connected with oxygen content pickup connected to pipeline of main condensate out of the limits of vacuum system of turboplant, for instance, after low-pressure heater of main condensate second in direction of main condensate flow and with regulating member installed on flash steam outlet pipeline of atmospheric deaerator of additional feed water.
EFFECT: increased economy and improved reliability of thermal power station.
