• Combustion reaction rate of the pulverized coal particle in the high temperature condition is dominated by mass transfer rate of oxidant. Thought it is common practice to estimate mass transfer rate of oxidant considering diffusion rate only, product gas prevents oxidant from mass transfer from bulk to the surface on the char particle especially in the high temperature condition such as oxygen-rich combustion. In this study, mass transfer rate of oxidant to the surface on the char particle is numerically estimated and effect of the product gas on mass transfer of oxidant is investigated.
