盐水预热器腐蚀原因的分析

Analysis on corrosion reasons of brine preheater

分析了盐水预热器腐蚀的原因,包括盐水腐蚀、应力腐蚀、杂散电流腐蚀和温差电池腐蚀。提出通过保证工艺,控制盐水的pH值、温度及杂散电流腐蚀等措施可使盐水预热器的运行状态得到改善。

Corrosion reasons of brine preheater were analysed, including brine corrosion, stress corrosion, stray current corrosion and thermocell corrosion. Several measures of improvement of operation status of brine preheater were put forward, such as ensure process, and control pH value of brine, temperature and stray current corrosion.
