摘　　要：介绍华能国际电力股份有限公司上安电厂600 M W机组凝结水系统概况，针对除氧器上水调门局部阻力较大，造成节流损失的问题，提出在50％～100％负荷时，保持除氧器上水调门及其旁路电动门全开的方法，并从经济性、安全性两方面分析该方法的经济效益和节能效果，认为该方法节能效果显著。This paper describes the 600 MW unit and conden-sate water system of Huaneng Power International Inc . Shang＆#39;an Power Plant ,aiming at a larger local resistance caused higher throttling losses at bypass electric valve of de-aerator feed water control valve ,proposes a method to reduce throttling losses by opening the bypass electric valve of de-aerator feed water control valve under the load of 50% ~100% ,and analyzes the safety ,economy ,and considers that economic benefit and the energy-saving effect of this method is remarkable .
