FIELD: thermal engineering; thermal power stations.
SUBSTANCE: proposed operating process of thermal power station is as follows. Boiler-generated steam is conveyed to turbine wherefrom it is supplied to condenser for condensing it; full-flow condensate is delivered by means of condensate pump to low-pressure regenerative heaters and then to high-pressure deaerator; makeup water is deaerated in atmospheric-pressure deaerator and conveyed to full-flow condensate path, vented steam being discharged from atmospheric-pressure deaerator into atmosphere. Flowrate of vented steam discharged from atmospheric-pressure deaerator is regulated with respect to desired content of oxygen dissolved in mixed flow of makeup water and full-flow condensate beyond vacuum system of turbine unit, for instance downstream of low-pressure heater second along full-flow-condensate path.
EFFECT: enhanced economic efficiency and operating reliability of thermal power station.
