The combustion process of pulverized coal in thermobalance is simplified in the paper. And total differential equations based on conservation of mass, energy and species law are obtained. Then the combustion process in thermobalance is simulated by numerical method. The results of numerical simulation show that the anthracite combustion procedures of the volatile and fixed carbon are independent of each other. The combustion rate of bituminite is obviously higher than that of anthracite and lean coal. The volatile helps the ignition of the fixed carbon and causes the combustion of fixed carbon to be earlier. The peak values of rate of mass loss of different coals are the same. Simulation results agree with experimental results, and the results demonstrate the numerical method of the model can be used to quantificationally predict the process of combustion in therobalance.
