The temperature of flue gas disposed by wet flue gas desulfurization is lower without gas heater (GGH) and large number of condensate which have strong corrosion toward the FRP flue, are produced by reason of condensation of the flue gas in the inner wall, FRP flue has the dual nature of both structural and functional materials and can meet the requirements of power plants. Firstly, this paper mainly introduced the application situation of FRP flue at home and abroad. The quantities of FRP flue installed are increasing abroad and FRP flue became one of important corrosion resistance materials in the developed country like American and Europe. The application of FRP flue start in recent years and a few of FRP flue was in the service, but the development of FRP flue is quick and the design standard and product standard of FRP flue have been published at home. In generally, the understanding in the design and construction is still lacking. Finally, the author discuss and research the resin material selection and joint design of FRP flue according to the FRP liner and FRP flue engineering which the author participate and design experience of FRP product.%经过湿法脱硫且不加装烟气加热装置的烟气的温度比较低，烟气在烟道内壁冷凝产生大量的冷凝液，对烟道的腐蚀很大，玻璃钢烟道集功能性和结构一体，能满足电厂的运行要求。本文首先阐述了玻璃钢烟道在国内外的应用研究现状，在国外玻璃钢烟道的安装数量不断增加，已经成为主要烟道防腐材料之一；国内玻璃钢烟道应用已有几年时间，发展较快，已经出版了相应的设计标准或产品标准。但总的来说，国内对玻璃钢烟道设计及施工认识还不够。最后作者利用自己参与的玻璃钢烟道、烟道工程及相关的玻璃钢制品的设计经验，对玻璃钢烟道树脂原材料的选材、玻璃钢烟道接口设计进行了简单的探讨和研究。
