摘要
分析了燃煤电厂烟气脱硫系统湿烟囱的腐蚀特性、腐蚀机理及影响因素。提出了不锈钢在湿烟囱中的腐蚀为一种冷凝薄液膜下多相作用的电化学腐蚀,探讨了湿烟囱的防腐措施以及湿烟囱用不锈钢的研究和开发。
The corrosion characteristics,corrosion mechanism and factors influencing corrosion were analysed and discussed. It was put forward that the corrosion of stainless steel in wet stack is multi- phase effected electrochemical corrosion under the condensed thin electrolyte film. The corrosion protection and the RD of stainless steels applied for wet stack were discussed.
