通过对火力发电厂脱硫烟囱防腐现状的调查，结合平顶山姚孟发电有限责任公司现场实际，制定了1号、2号机组烟囱轻质玻化陶瓷砖复合防腐方案，并在工程现场进行了实施，运行表明该防腐方案效果良好，值得参考。最后，对脱硫烟囱防腐给出了建议。

By surveying anti-corrosion situation of the flue gas esulfurization(FGD) chimney in the coal-fired power plants, and combined with the engineering practice of Pingdingshan Yaomeng Power Co., Ltd., a composite anti-corrosion plan about light weight vitrified ceramic tile for 1#& 2# unit chimneys is presented and implemented with good results. In the end, some suggestions are proposed about the anti-corrosion of FGD chimney.
