In this research, the CFD simulation of a pulverized coal combustion field formed in a coal combustion test furnace, of which the coal feeding rate is about 100kg-coal/h, is performed using the model employing tabulated devolatilization process (TDP model), which can take into account the effect of the particle heating rate on the amount of volatile and devolatilization rate. To verify the applicability of the TDP model for the combustion field, the measurement of particle velocity using a laser-Doppler velocimetry (LDV) is also performed. The simulation result with the TDP model is compared with the LDV measurement result and the simulation result with the conventional model. As a result, it is found that the result predicted by the TDP model is more accurate than that predicted by the conventional model.
