摘要
为了研究显微组分对煤及焦的燃烧特性的影响，从显微组分和煤阶的角度描述反应性能的变化。本文提出了综合考虑显微组分和煤阶的岩相因子，较好的表示煤的类型和煤化程度对燃烧特性的影响，较前人孤立地看待显微组分和煤阶的影响是一大进步。用岩相因子与煤的着火温度关联，取得比较满意的结果。
Since the characteristics of maceral varied with coal rank, it is difficult to predict combustion characteristics of coal and chars based on maceral composition or on coal rank A new petrographic factor P F, which combines the influence of both the maceral and the rank, is proposed to describe the variation of maceral with rank P F consists of reactive maceral, mean vitrinite reflectance A high value of P F means high reactivity Ignition temperature has good corelation with P F Taking account of the effects of maceral and rank on reactivity, the petrographic factor is considered to be a new concept and a great improvement in application of petrography on coal combustion
