THERMAL POWER STATION OPERATION METHOD Russian patent published in 2004 - IPC

Abstract RU 2230198 C2

FIELD: heat power engineering. SUBSTANCE: according to proposed method, to provide operation of thermal power station, heating system water is heated in system heaters by steam of heat extraction turbine steam extractions, makeup water of heating system is deaerated in vacuum dearator before delivering into system return pipeline. For this purpose source water and superheated water are delivered into deaerator. Preset concentration of dissolved oxygen in dearated make-up water is maintained by sequential control of flow rate and temperature of heating agent. If dissolved oxygen concentration exceeds preset value, first flow rate of superheated water is increased and then, in case of necessity, temperature of heating agent is increased. In case of drop of dissolved oxygen concentration relative to preset level, first heating agent temperature is reduced and then flow rate of superheated water is decreased. EFFECT: increased economy and provision of reliability of thermal power station. 1 dwg
