摘　　要：对不同灰分的烟煤、无烟煤煤样,采用缓慢灰化法测定其灰分。通过进行检查性灼烧和不进行检查性灼烧的比对试验表明,2种方法的测定结果没有显著性差异,因此采用缓慢灰化法测定煤中的灰分时,在日常生产的常规分析中可不必进行检查性灼烧。For anthracite and bituminous coal samples with different ash yields, the slow ashing method was applied to determine ash yield in this paper. Through the comparative experiments with and without ignition check method, it was indicated that there was no significant difference, so it was not necessary to do the ignition check in routine analysis when the slow ashing method was used.
