摘　　要：煤质特性是影响煤着火特性的重要因素,通过一维燃烧炉对动力用煤的着火特性进行试验研究,并对影响煤粉着火过程的煤质特性进行了分析,利用挥发分、水分、灰分、固定碳含量对着火特性的影响,建立了着火判别指数δ,提出了利用煤质分析数据计算着火温度判别指数δ,从而判断动力煤的着火特性方法,并对计算所得着火温度与试验测得的着火温度进行拟合,二者的相关系数为0.9571,表明这种评价煤着火特性的方法比较精确、可靠。The coal quality characteristics constitute an important factor influencing its ignition ones.The authors have experimentally studied the ignition characteristics of coal for use in power plants in a one-dimensional combustion furnace and analyzed the coal quality characteristics influencing the ignition process of the pulverized coal.By utilizing the influence of the volatile,water,ash and fixed carbon content on the ignition characteristics of the coal,an ignition judgement index δ was established and a m...
