通过差示量热扫描(DSC)试验,测定出蒙西地区侏罗纪煤自燃氧化过程的吸、放热量。按煤样吸、放热规律,把蒙西地区侏罗纪煤样DSC曲线划分为3个不同的典型阶段;分析了不同升温速率下的DSC曲线,并对蒙西地区侏罗纪煤样进行了动力学分析,在Kissinger方法的基础上,计算得出了蒙西地区侏罗纪煤在低温氧化过程中的表观活化能。确定蒙西侏罗纪煤样氧化自燃过程中的特征及动力学参数。
Differential scanning calorimetry (DSC) experiment was conducted to measure en- dothermic and exothermic altitude of Jurassic coal in western Inner Mongolia. Based on endothermic and exothermic laws in different temperature rising velocity, the DSC curve was divided into 3 phases and kinetics analysis was undertaken to calculate the apparent activation energy of Juras- sic coal during low temperature oxidation in western Inner Mongolia based on kissinger method. Then the characteristics and kinetics parameters of the coal sample during oxidation and spontaneous combustion were determined.
