摘要
运用热重分析方法对铁法晓明煤矿的3种煤样在不同升温速率下进行动力学实验,得出实验煤样在不同的升温速率时的4个特征温度值;且随升温速率的提高,煤样的热重(TG)曲线向右偏移。计算得出3种煤样从常温到着火温度前活化能随升温速率增大而增大,通过进一步的分析,认为实验采用较低的升温速率更有助于得出较为准确活化能值。
The thermal weight analysis method was applied to do the dynamic test with three coal samples from Tiefa Xiaoming Mine with different temperature rising rates.There were four feature temperature values obtained for the test coal with different temperature rising rates.With the temperature rising rate increased,TG curve of the coal sample was displaced to right.The calculation showed that activity of the three coal samples would be increased with the temperature rising rates from the normal temperature to th...
