小型电厂低真空循环水供热的节能分析

Analysis on low vacuum circulating water heating energy-saving on the small-scale power plant

针对热电联产电厂内存在大量循环冷却水余热的现状,提出了以电厂低真空循环水供热的模式,并结合某低真空循环水改造项目,通过实际运行数据的计算,分析了其产生的节能效益,指出低真空循环水供热对小型电厂来说是一种投资小、见效快的方式。

In light of large amount of cycling cooling water waste heat status of thermal-electric power manufacturer plant,the paper puts forward low vacuum circulating water heating mode. Combining with the low vacuum circulating water transformation project,through calculating actual operation data,it analyzes its energy saving efficiency,and finally points out that： low vacuum circulating water heating is a small-investment and fast-efficiency method for small-scale power plant.
