摘　　要：分析脱硫后烟气的腐蚀性,并结合技术、经济等因素论证燃煤电厂湿法脱硫(FGD)装置加装GGH的利与弊。分析认为,燃煤电厂湿法脱硫装置不设GGH是可行性的,建议新建脱硫项目不装设GGH;已安装GGH的脱硫装置,需对其尾部设备采取防腐措施。The corrosivity of flue gas after desulfuration has been analysed, and combined with technical and economical factors etc. , the advantages and disadvantages for wet desulfuration facility with or without gas - gas heat exchanger （GGHE） being expounded. It is believed that the wet desulfuration facility without GGHE in coal - fired power plants is feasible, and then it is recommended that the newly constructed desulfuration project to use facility without GGHE, and the original desulfuration facility with GGHE must adopt anti-corrosion measures for its heat recovery equipments.
