摘要
采用马弗炉和四角燃烧炉对煤中矿物质在加热过程中组分和含量变化利用Ｘ－射线衍射进行分析。结果表明，在燃烧炉内煤灰矿物质行为与在马弗炉内加热煤灰的矿物质行为基本一致；煤灰矿物质行为与原煤中矿物组成及含量关系较大。
The vartiation of components of minerals in coal, in the process of heating in muffle furnace and quadrangular combustion furnace was analyced with X ray diffractometer.The results show that the behaviour of coal ash in combustion furnace is similar to that in muffle furnace, and the behaviour of coal ash is greatly related to the compositions of raw coals.
