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。

Abstract

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.
