摘要:

针对干熄焦余热锅炉入口烟道外部壳体易损坏情况,分析壳体损坏原因后,对锅炉入口烟道内衬进行了合理有效改进,由原来的整体浇注式拱顶结构改为楔形砖砌筑形式,后期运行未出现任何异常现象,延长了锅炉入口烟道使用寿命,稳定干熄焦生产,降低了生产运行成本。

Abstract:

In this paper,analysis is made for the causes to the damage at outer shell of the inlet duct of WHB (waste heat boiler).Improvements are also given for a better inlet duct lining structure,i.e.the original monolith concreted arch is changed to wedge type brick-laid arch structure,which runs very well without any problem and with extended service life of the WHB inlet duct,stabilized CDQ production and less operating cost.
