摘要

通过对有关管样的试验分析

认为华能福州电厂2号炉水冷壁爆管是一起因柠檬酸酸洗不当引发的氢损伤爆管。分析了由柠檬酸引起的垢下氢腐蚀损伤特征

并通过采用羟基乙酸+甲酸进行再次酸洗

消除了隐患。迄今

2号炉水冷壁管运行正常

没有再发生垢下腐蚀和氢损伤。

Abstract

Directing against the tube-burst failure of water-wall in boiler no.2 of Huaneng Fuzhou Power Plant

through test and analysis of related tube samples

it is believed that the said failure is due to tube-burst of hydrogen damage resulting from unsuitable acid cleaning with citric acid solution.The characteristics of hydrogen corrosion damage under scale caused by citric acid have been analysed

and the said hydrogen damage under scale being preliminarily approached. After adopting hydroxyacetic acid + formic acid to carry out cleaning again

the hidden peril has been removed.So far

the water-wall of boiler no.2 is in normal operation

corrosion and hydrogen demage under scale haven't been discovered again.
