FIELD: heat engineering; thermal power stations. SUBSTANCE: according to proposed method, heating system water is heated is system heaters by steam of heating extractions of extraction turbine and heating system feed water is deaerated in vacuum deaerator before delivering into return pipeline of heating system. For this purpose source water and superheated water are fed into deaerator. Preset concentration of carbon dioxide in deaerated feed water is maintained by sequential regulation of source water temperature and superheated water flow rate. In case of rise of carbon dioxide concentration relative to preset value, first source water temperature is raised and then, if necessary, flow rate of superheated water is increased. In case of drop of carbon dioxide concentration relative to preset value, first flow rate of superheated water is decreased and then source water temperature. EFFECT: improved reliability and increased economy of thermal power station. 2 cl, 1 dwg
