摘要/Abstract

摘要： 介绍了中孚电力公司#2 440t/h CFB锅炉的技术性能及其主要技术参数。论述了锅炉在运行中频繁出现过热器冷热屏超温、爆管和炉膛内水冷壁局部严重磨损等问题，严重影响了机组的安全运行。采取了相应的措施，对锅炉过热器冷热屏进行了改造，改造后的过热器冷热屏运行状况良好，没有出现过热器冷热屏因超温而发生爆管事故。

Abstract: The technical characteristics and main technical parameters of 440t/h CFB boiler No.2 in Zhongfu Electric Power Corporation were introduced. Some problems were occurred frequently in the boiler operation which includes overtemperature in cool panel and hot panel of superheater, pipe explosion and local serious wear of watercooled wall in furnace. Theses problems influenced on safety operation of unit seriously. The relevant measures were adopted, the cool panel and hot panel of superheater were reformed. After the reformation, the cool panel and hot panel of superheater operate well, and pipe explosion due to overtemperature has not occurred.

Key words: circulating fluidized bed boiler, boiler heating surface, cool panel and hot panel of superheater, over-temperature, water-cooled wall, wear, reformation
