FIELD: heat and power engineering. SUBSTANCE: steam power station has at least two extraction turbines 1, source water piping 6 to supply make-up water to heating system where heating surface of turbine condenser 7, water-cooled water heater 8, chemical water treatment system 9, and vacuum deaerator 11 with intermediate vessel 12 are connected in series. Bottom heating-system water heater 17 and top one 18 of one of turbines and water-cooled water heater 8 for heating source water are connected in series in deaerated feed-water piping 16 between vacuum deaerator 11 and storage tank 15. Heating agent piping 19 of vacuum deaerator 11 is connected to feed-water piping 16 upstream of water-cooled water heater 8. EFFECT: improved design. 1 dwg
