摘要
湿法烟气脱硫装置因其处理烟气量大、脱硫率高、运行周期长、运营成本适中,已成为国内外火电厂烟气脱硫的主导装置。但该装置腐蚀环境苛刻,防腐蚀是FGD装置中的一个重要环节,而作为一种普通采用的鳞片衬里材料,在国内的一些应用案例,出现了一些防腐蚀失效甚至失败的情况,本文就一些FGD装置的失效情况进行分析和总结,找出一些原因以及对策,从而为后续烟气脱硫装置的防腐蚀技术提供了可靠的技术借鉴。
FGD is now the most common desulfric equipment in China now on the basis of its benefits, and glass flaked vinyl ester is most employed as anti-corroiosn lining thereby. However in these rapid booming market, some cases concerning the default lining were also ongoing, in this paper, we discussed and analyzed these default cases foe some conclusion, which in return are of assistance to the sustained anti-corrosion lining in these FGD.
