定量研究了常见无机矿物对无烟煤发热量的影响．结果表明，方解石的分解率随其含量提高而降低，其吸热偏差可由分解率推算；高岭石主要分解产物是无定形非晶态物，少量转变为莫来石，发热量测定偏差可按其完全分解吸热计算；硫铁矿燃烧放热造成发热量测定结果偏高；石英没有变化，石膏脱水转变热效应很小，二者对发热量影响可以忽略不计．多种矿物复合影响试验表明，在矿物总量较高时校正值为各矿物独立热效应之和，矿物总量较低时按各矿物独立热效应之和计算校正值略低于实测值 The effects of common inorganic minerals on anthracite calorific value were studied quantitatively. The results show that the decomposition rate of calcite decreases with the increase of its content, and its endothermic deviation can be deduced from the decomposition rate. The main decomposition product of kaolinite is amorphous amorphous material, with a small amount of mullite, Which completely decomposed the endothermic calculation; pyrite combustion heat caused by high heat measurement results; no change in quartz, gypsum dehydration transition thermal effect is very small, both on the calorie impact can be ignored. Multiple mineral compound impact tests show that the correction value is the sum of the independent thermal effects of all minerals when the total amount of minerals is high and the correction value is slightly lower than the sum of the individual thermal effects of each mineral when the total amount of minerals is low
