摘要

针对温州发电有限公司1号锅炉排烟温度偏高的问题

提出了适当增加低温再热器和主省煤器受热面的改造方案。改造后

排烟温度下降了20℃

锅炉效率增加了0.8个百分点。按锅炉年运行5000h

一年可节约燃料2240t

经济效益显著。

Abstract

Directing against the problem of somewhat higher exhaust gas temperature from boiler no 1 in Wenzhou PowerGeneration Co Ltd

a retrofitting scheme of suitably increasing the heating surface of lowtemperature superheater and of the main economizer has been put forward. After retrofitting

the exhaust gas temperature reduces 20℃

the boiler efficiency increasing 0.8 percentage point. According to annual operation hours to be 5000 h

and price of coal to be 320 yuan （RMB） per ton

the annual coalsaving can reach 2240 t

saving fuel cost valued at 0.72 million yuan （RMB）

economic benefit being obvious.
