火力发电厂湿烟囱渗漏原因分析及防腐改造

On analysis of reasons for leakage at wet chimney of thermal power plants and anti-corrosion reconstruction

结合忻州广宇煤电有限公司烟囱防腐的改造案例,对石灰石—石膏湿法脱硫烟囱渗漏的原因及改造方案进行了分析比较,并对烟囱钛—钢复合板内筒的设计进行了详细阐述,为火力发电厂旧烟囱防腐改造积累了经验。

Combining with the reconstruction case for the chimney anti-corrosion at Xinzhou Guangyu Coal Industry and Coal Co. ,Ltd, the paper analyzes and compares the reasons for the leakage of limestone-gypsum wet desulphurization chimney and reconstruction scheme, and illustrates the design for chimney titanium-steal composite panel inside cylinder, so as to accumulate experience for the anti-corrosion reconstruction of old chimney at thermal power plants.
