电站锅炉水冷壁频繁腐蚀穿孔分析
Analysis of Frequent Corrosion Perforation of Power Station Boiler Water Wall
摘要
Abstract
The leakage accident of water wall tube frequently occurred in high load area, in order to find the cause, it analyzed the water wall tube for the accident through consulting data, macroscopic examination, wall thickness measurement and strength check, hardness testing, metallographic analysis, mechanical performance analysis, measuring expansion and other methods. The results showed that the underdeposit corrosion is the direct reason lead to corrosion and perforation; poor quality steam water, low load operation and other unreasonable operation factors are the primary cause of frequent leakage of water wall. Practice showed that the power station boiler easily occurred similar defects in the high pressure range, when the water quality is not up to the standard.关键词
