Some recent developments in pulverized coal combustion simulation including our research are summarized. Tabulated-Devolatilization-Process model has capability to predict devolatilization rate under different heating rate conditions. Oxidation rate of pulverized coal char increases with heating rate when char is generated. Devolatilization process inhibits mass transfer of oxidant to pulverized coal char particle and decreases oxidation rate. The inhibition rate can be modeled with a simple formula. So called Flamelet approach is successfully applied to pulverized coal combustion simulation instead of solving the conservation equations of mass fraction of chemical species and energy.
