摘　　要：煤的格金低温干馏试验是一个综合性试验,既可得到结焦性和干馏物产率的指标,又可得到热解水产率和干馏总水分产率,在煤化工的实际生产和研究中,煤的格金低温干馏试验有很重要的意义。通过大量试验结果对比,认为升温速度、冷凝温度及支管插入深度和时间等是影响试验结果的主要因素,并指出了实验中应注意的问题。Coal low temperature Gray-King assay is an integrated test,not only can get coking property and pyrolyzate yield indices,but also pyrolytic water yield and total moisture of dry distillation yield.In coal chemical engineering practical production and research,coal low temperature Gray-King assay has very important significance.Through contrast of large amount test results,considered that the temperature rising rate,condensing temperature,pipe branching inserting length and time are major factors impacting test results,and pointed out issues to be noted in test.
