摘　　要：针对煤气化联合循环(IGCC)气化炉除灰渣系统,以某IGCC示范项目为依托,介绍了气化炉除灰渣系统的工程概况与设计原始资料,对气化炉除灰渣工艺的特点进行了设计,并对除灰渣系统设计提出了建议:除渣系统采用机械除渣方式,捞渣机采用上回链的刮板捞渣机;采用空分系统产生的热氮气代替压缩空气作为气力输灰的气源,合理设置除尘程序。Aiming at the ash and slag removal system of IGCC gasifier.Taking an IGCC demonstration project as an example,this paper introduces the general situation of the project and the original design data of the ash and slag removal system of the gasifier,and designs the characteristics of the ash and slag removal process of the gasifier.Some suggestions are put forward for the design of ash and slag removal system,such as mechanical slag removal method for slag removal system,scraper slag bailer with upper return chain,hot nitrogen generated by air separation system instead of compressed air as air source for pneumatic ash transportation,and reasonable dust removal program.
