摘要

模拟亚临界汽包炉全挥发处理(AVT)环境

在高温无氧碱性条件下

采用电化学和试片表面金相分析方法

对氯离子(Cl-)在水冷壁管内表面(向火侧)发生浓缩时的腐蚀情况

包括不同Cl-质量浓度对金属表面钝态膜的影响

进行了研究。结果表明:当Cl-质量浓度≤3.00mg/L时

金属膜电阻较大

金属膜完整;当Cl-质量浓度3.00mg/L时

金属膜电阻急剧减小

金属表面出现点蚀

且随Cl-质量浓度增大

金属表面腐蚀加重。

Abstract

Under all volatile treatment(AVT)working conditions of subcritical drum boiler

in high temperature anaerobic alkaline environment

the effect of Cl-on passive film on metal surface when Cl-was concentrated in the inner surface of the wall tube(the side facing the fire)was investigated

by electrochemical online test and the surface topography images.The results show that

when the Cl-concentration is equal or lower than 3.00mg/L

the metal film resistance is large and the metal film is complete.While when the Cl-concentration is higher than 3.00mg/L

the metal film resistance drops sharply

and pitting corrosion occurs on the metal surface.Moreover

the corrosion on the metal surface gets severe with the increasing Cl-concentration.
