FIELD: power engineering.
SUBSTANCE: thermal power plant containing the boiler, the heating turbine with steam extractions connected to feedwater heaters, the additional feedwater deaerator with connected to it source water pipeline and branch pipes of supply and discharge of the desorbing agent, the deaerator storage container connected by the pipeline of deaerated additional feedwater with the main condensate pipeline of the turbine branch pipes for supply and discharge of the desorbing agent of the additional feedwater deaerator are joined to the gas pipeline connected to boiler burners, and the pipeline of deaerated additional feedwater is connected to the main condensate pipeline of the turbine upstream the cooler of the main ejectors and the cooler of the turbine sealing steam.
EFFECT: invention allows to increase profitability of thermal power plant by an exception of costs for deaeration steam and efficient cooling of the cooler of the main ejectors and the cooler of the turbine sealing steam.
