Analysis on Slag Hanging Operation of Gasifier in Pulverized Coal Gasification Technology
During the operation of the gasifier,the water-cooled wall castables are prone to fall off and the slag is loose,which will cause frequent leakage of the water-cooled wall and seriously affect the safe,stable and long-term operation of the gasifier.In this paper,referring to the slag hanging experience of the gasifiers of company 1,company 2 and company 3 in the actual operating conditions,combined with their technological process and operating data,by comparing and analyzing the operating conditions of different coal ash components and furnace temperatures,the correlation between different coal qualities,coal ash melting points and slag formation was revealed.
