本文对颗粒煤在激光加热条件下的着火和燃烧进行了数值模拟。采用的是一个简单的煤粒着火与燃烧的一维模型。该模型采用了热解和双平行反应模型，考虑了煤粒表面的多相反应和气相的基元反应以及气相中的传热与传质。从获得的煤粒表面和气相空间的温度随时间的变化规律，可以判断不同煤种的着火方式。
The paper simulates the ignition and combustion of granular coal under laser heating conditions. Using a simple one-dimensional model of coal ignition and combustion. The model uses pyrolysis and double parallel reaction model, taking into account the multiphase reaction on the surface of coal particles and gas phase reaction and gas phase heat transfer and mass transfer. From the obtained coal particle surface and the gas phase temperature changes with time, we can judge the different types of coal ignition.
