摘　　要：介绍Shell粉煤气化工艺中飞灰的形成过程及其特性,对煤灰的熔融性进行探析并提出稳定气化炉运行的操作建议。煤灰的熔融特性不仅与灰的成分有关,还与燃烧过程中灰中各成分之间的相互作用有关。灰熔融性温度主要取决于煤中的矿物组成、其氧化物的成分和配比及燃烧气氛等。The process of fly ash formation and its features in Shell pulverized-coal gasification are introduced,the ash fusion analyzed and the operation proposal for a stable running of gasifier put forward.The ash fusion is not only related to the ash composition,but also to the interaction among the components in the ash during the combustion process.The temperature of ash fusion is mainly depending on the mineral composition in the coal,the composition and ratio of its oxides and combustion atmosphere.
