摘要

针对伊犁第二火电厂 2台CG 130 /3.82M12型中压锅炉运行以来存在的排烟温度高和热风温度高问题

研究制定了相应的改造方案

即恢复锅炉 10 7m2 的过热器面积

增加部分省煤器受热面积

在尾部烟道加装 8台蒸汽吹灰器。改造后运行表明

排烟温度降低了 30℃

热风温度降低了 10 0℃

效果良好。

Abstract

In view of troublesome problems of high exhaust gas temperature and high hot air temperature having existed after putting two CG-130/3.82-M12 type boilers into operation at Yili Thermal Power Plant NO.2

corresponding retrofitting schemes have been studied and worked out

namely renewing 107m 2 area of superheater in the boiler

increasing heating surface area of a party of the economizer

adding 8 steam soot-blowers in the heat recovery gas duct. The operation after retrofitting shows

the exhaust gas temperature having been lowered by 30℃

the hot air temperature by 100℃

obtaining good results of operation.
