摘要
本文用热天平考察了平朔煤、红阳煤、大同煤和东胜煤显微组分的燃烧特性，以及原生矿物质对显微组分燃烧的影响。研究表明，各显微组分的燃烧特征温度，镜质组低于惰质组，壳质组在燃烧的前、中期，特征温度较低，在燃烧后期，与其它两个显微组分的特征温度差值变小。原生矿物质对显微组分的燃烧有抑制作用，使燃烧特征温度升高。
The combustion characteristics of macerals from four coals and the effcet of inherent mineral matter on comubstion were investigated by means of thermogravimetry.According to characteristic temperature in weight loss curve of TGA,the combustion behavior of vitrinite concentrate was found to be better than that of inertinite concentrate.The characteristic temperature of exinite concentrate is lower than that of vitrinite concentrate in the earlier and middle stage of combustion,but tends to be higher in the later stage.The characteristic temperature of maceral concentrates after demineralization becomes lower than respective original concentrates.
