摘要
利用实验模拟煤的自然发火过程,运用了非定温热重分析和微分热重分析手段,对4种煤样做了低温氧化实验研究,探讨了煤炭自然发火机理。运用Arrhenius典型方程分析出不同的热重数据,求出了煤样的动力参数,并讨论了煤低温氧化阶段的活化能和煤的自燃倾向性之间的关系。活化能可以作为划分煤自燃倾向性的参考指标。
The experiments were taken used to spontaneous simulate combustion of coal in this study. The non-fixed temperature thermogravimetry and derivative thermogravimetry were used to study the course of low temperature thermal oxidizing decomposition on 4 coal samples, then the spontaneous combustion mechanism of coal was discussed. By Arrhenius equation, different thermogravimetry data and kinetic parameters . The relation of spontaneous combustion tendency and activation energy was studied. It showed that activation energy can be a consult index of divide spontaneous combustion tendency.
