Failure Analysis of A Gasification Boiler
-
摘要: 针对某气化锅炉使用不到两年发生泄漏的情况,对泄漏部位进行了化学分析、金相检验、SEM等宏观和微观检验以及附着物X射线衍射、EDS分析。结果表明,泄漏主要是由于高温硫化物腐蚀造成的,并提出了改进建议。Abstract: For the leakage of a gasification boiler which runs for less than two years,comprehenisve analyses including chemical analysis,metallography analysis,SEM,corrosion product X-ray diffraction,and EDS analysis were made on the part of leakage.The results show that failure of the boiler is due to corrosion of sulferation at high temperature,thus some advices were put forward in this paper.
