摘　　要：针对高碱煤各类沾污判别指标进行了逐一分析,包括各类结渣判别指标与沾污判别指标,并从沾污结渣机理与各判别指标间内在关系进行了深入分析,进一步明确了各类沾污结渣预测指标作为判别沾污结渣程度的原因,分析了各种不同结渣判别指标和沾污判别指标对于准东高碱煤沾污结渣判别的适用性,为准东煤沾污结渣程度判别提供了支持。The identification indicators of high alkali coal fouling and slagging were analyzed one by one,and the in-depth analysis was made from the mechanism of fouling and slagging and the internal relationship between each discriminant index.The reasons of all kinds of fouling and slagging prediction indicators for judging the degree of fouling and slagging were further clarified,and the applicability of various slagging and fouling criteria for judging Zhundong high alkali coal fouling and slagging degree was analyzed,which provided supports for the judgment of Zhundong coal fouling and slagging degree.
