贴玻化砖类钢套筒烟囱防腐现状分析

Analysis of Steel Sleeve Stacks with Vitrified Tile Anti-corrosion Treatment

近年来新建电厂多采用石灰石─石膏湿法脱硫方法,为了适应此烟气工况的改变,考虑到成本等因素采用铺贴玻化砖作为烟囱防腐工艺的电厂很多。此类烟囱运行已有几年时间,现在的回访、调研资料基本可以反映此类烟囱的实际防腐效果。

In recent years, new built power plants often adopt the limestone-gypsum WFGD system. In order to adapt to this change, and also considering factors such as cost and so on, many power plants use the vitrified tile as the anti-corrosion treatment for the stack. Such kind of stacks have been put into commission for several years, so the back-visiting and report can show the anti-corrosion actual effect.
