Abstract�� The comparative study between CFD numerical results of pulverized coal combustion process and the experimental data is becoming an important measure for validating mathematical models and direct engineering practice. The CFD commercial software, FLUENT, was used to simulate the pulverized coal flow and combustion. Mixture-Fraction/PDF model was used to simulate turbulent combustion; P-1 radiation model was used for simulating radiation heat transfer; the Langrange/Euler-s method was used for dealing with momentum, mass and energy exchange between the solid and the gas phase; the two-competing rates model for devolatilization and the kinitics/diffusion limited combustion model for simulating surface combustion of pulverized coal particles. The result of simulation is consistent with the data from actual combustion process. The simulation results show the rules of the volatile releasing and combustion processing of coke, which could provide important references to improve the combustion of the pulverized coal.
