摘　　要：湿法脱硫系统取消了回转式GGH后,出现了脱硫后的烟道和烟囱腐蚀,烟囱雨现象及烟道堵塞等问题。着重介绍、对比了防止烟道、烟囱腐蚀的防腐材料以及尾部烟气再热新技术。简述了烟道、烟囱的结构优化以及烟道防堵等措施。After the FGD eliminates the rotary GGH, some phenomena such as flue and stack erosion after desulfurization, stack rain and flue blocking are observed. The anticorrosive material for preventing the corrosion of the flue and the chimney as well as the new technology of tail gas reheating are emphatically introduced and compared. The structure optimization of the flue and the chimney and the measures to prevent the blockage are also described.
