摘要
本文简要介绍了移动床、流化床、气流床气化技术、地下气化的现状,重点针对各种典型煤气化技术的特点,结合已使用煤种的煤质情况及使用不同煤质出现的一些问题,分析了不同气化技术对煤质的要求,包括对入炉煤的粒度、灰分、水分、反应性、热稳定性、落下强度、黏结性、可磨性、灰熔融性温度、灰渣黏度及成浆性等的要求。
This text briefly introduces the gasification technology of moving bed,fluidized bed and the current status of underground coal gasification and analyzes the requirements of different gasification technologies on coal quality including the requirements on granularity,ash content,moisture content,reactiveness,stability,drop strength,cohesiveness,grindability,fusion temperature of coal ash,viscosity of clinker and slurryability of the coal put into furnace.
