神华煤燃烧初始阶段表面形态变化的试验研究

通过沉降炉试验取得了不同停留时间的煤焦样品,通过扫描电镜进行分析,描述了整个燃烧的初始阶段煤粒表面形态的变化,初步探讨了煤粒表面形态变化与燃尽度的变化的关系,为理解燃烧初始阶段煤的行为提供帮助。 The paper described the change of surface morphology in the initial stage of combustion and discussed the relationship between burnout degree and surface morphology change by the SEM analysis of coke which got by different resident time in drop tube furnace, and the paper describe the behavior in the initial stage of combustion
