Numerical Simulation Study on the Spontaneous Combustion Process of the Column Coal Sample

The coal self-ignition process can be successfully simulated with the coal spontaneous combustion experimental oven. But it can抰 be simulated for all kind of spontaneous combustion conditions, because of the lots of many coal can be used in the experiment. Based on the structure of the column experimental oven and the characteristics of the coal sample spontaneous combustion. The two dimensions mathematical model is developed. Then, the numerical calculation is conducted with the finity difference . Finally, according to the experiments of Yanzhou coal sample, the results of the numerical simulation on the column coal spontaneous combustion are consistent with the experiments.
