摘　　要：介绍了一种冷源系统优化改造技术,并将该技术在国内某300MW机组投入应用,对其经济性进行了计算分析,得出以下结论:冷源系统改造技术可大幅降低凝汽器运行压力,相比于改造前,凝汽器运行压力降低1.2 kPa,机组年平均标煤耗降低3.6g/kW·h,年节煤效益达326.7万元,节能效益显著。This article introduced a technology of reconstruction for the cold source system. And applied in a 300 MW unit, the economic benifits were analyzed,the result showed that： this technology can substantially depress the pressure of steam condenser, comparing with the pressure before reconstruction, the pressure depressed 1.2 kPa; after its application, the standard coal consumption of the unit depressed 3.6g/kW ＂h,the energy-saving benefits is about 3.267 million yuan each year.

关 键 词：冷源系统 凝汽器压力 标煤耗 节能效益
