METHOD OF OPERATION OF THERMAL POWER STATION Russian patent published in 2003 - IPC

Abstract RU 2220291 C1

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