工艺烧嘴是德士古水煤浆气化装置的关键部件,其运行周期直接决定了气化炉的长周期安全稳定运行.从宏观检查、微观金相分析、硬度检测、能谱分析等多角度对气化炉烧嘴外氧喷头端盖因Cl、S腐蚀导致失效的原因进行了分析,研究出材料组成元素及优化夹套结构设计等针对性措施,以延长工艺烧嘴使用寿命.
Failure analysis of Texaco coal water slurry gasification feed injector outer tip cap
Feed injector is the key equipment of Texaco coal water slurry gasification process,and its operation status directly determines the operation cycle,safety and stability of a gasifier.Based on macroscopic inspection,microscopic metallographic analysis,hardness detection and energy spectrum analysis,the failure mechanism of a feed injector outer tip cap is analyzed,which caused by Cl and S corrosion.The service life of the feed injector is prolonged by studying the material composition elements and optimizing the design of jacket cooling structure.
