摘　　要：介绍了华能公司IGCC机组干煤粉气化工艺,针对干煤粉气化炉一段烧嘴水平偏置改造后,产渣量大幅提升,导致烧嘴罩发生漫渣、泄漏的问题,通过采取提高烧嘴罩探入深度、优化配煤方式控制气化炉产渣量、改造粉煤给料罐底锥稳定煤线波动等措施,进一步提升了烧嘴罩运行的稳定性,基本避免了烧嘴罩发生漫渣、泄漏现象。The dry pulverized coal gasification process of IGCC unit of Huaneng Co.,Ltd.was introduced.Aiming at the problem that the slag production of dry pulverized coal gasifier was greatly increased after the horizontal offset modification of the primary burner,which led to the slag overflow and leakage of the burner cap,the operation stability of the burner cap was further improved by increasing the probe depth of the burner cap,optimizing the coal blending method to control the slag production of the gasifier,and modifying the bottom cone of the pulverized coal feeding tank to stabilize the fluctuation of the coal streak.This basically prevented the burner cap from slag overflow and leakage.
