METHOD OF THERMAL DEAERATION OF WATER Russian patent published in 2003 - IPC

Abstract RU 2220297 C1

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