Abstract:

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.
