摘要(Abstract):
分析了发电厂无旁路脱硫系统内部的腐蚀环境和腐蚀机理,介绍了国内外无旁路脱硫系统的防腐技术现状,在分析各防腐材料特性的基础上,讨论了无旁路脱硫系统中各设备的防腐措施,为防腐方案的选择提供参考。
The paper analyzes corrosion environment and corrosion mechanism in non-bypass desulphurization system and introduces current anticorrosion technologies both here and abroad.On the basis of analyzing properties of various anti-rot materials,the paper discusses anticorrosion scheme for non-bypass system,which provides reference to anticorrosion scheme selection.
