摘　　要：对高灰分、高挥发分煤的发热量测定方法进行对比分析。研究结果表明,对于高灰分的煤样,用石棉绒做衬垫和用擦镜纸包裹煤样均燃烧完全,其测定结果基本一致且误差满足GB/T213—2008《煤的发热量测定方法》规定的重复性限要求。对于高挥发分的煤样,除了可采用GB/T 213—2008测定方法外,还可采取减少煤样的测定方法。采取减少煤样的发热量测定方法较为简单,可减少试验时间及提高工作效率。Determination of calorific value of high-ash coal and high-volatile coal were analyzed. It is shown that for high-ash coal, the results of coal sample with padded asbestos wool and lens wiping paper wrapped were basically the same, combustion was fully and the error meet the “Determination of calorific value of coal” （ GB/T213-2008 ） repeatability requirements.For high volatile coal, in addition to measuring method “Determination of calorific value of coal” （GB/T213-2008） mentioned, the measurement method of reducing coal samples could be adopted.Reducing coal sample method was easy to operate, reducing test timeand increasing efficiency.
