| 摘 要： | 煤的粒径和矿物含量对煤的燃烧有非常重要的影响。选用山西晋城无烟煤为研究对象,采用浮沉法、激光粒度分析等手段定量的研究了煤粉中矿物的分布规律,并提出了一种定量计算矿物在煤粉中分布的计算方法。结果表明,计算结果与筛分结果重复性比较好,且与许多学者的研究结果一致。

| Abstract: | Sizes and mineral contents of coal particles have important effects on the coal combustion.The anthracite coal in Jincheng Mining Co.Ltd.Shanxi was selected to quantitatively investigate the mineral distribution in coal fines in this paper by means of such tools as floatation separation method,laser grain-size analysis.A quantitatively calculating method for determining the mineral distribution in coal fines has been developed.The result shows that the calculating results and the screening results are of repeatable nature,and accord with the previous results presented by other scholars. |
