To estimate the properties about chemical reaction rate, the Drop Tube Furnace (DTF) is generally used as an experimental apparatus. In this study, the heat and mass transfer around a single pulverized coal particle that is heated in the flow field reproducing the DTF is numerically simulated as the solid-gas two-phase flow. By comparisons of numerically analyzed results, the influence of the different coal in rank, coal particle diameter, gas temperature distribution and velocity distribution in the DTF for the thermal behavior of the pulverized coal particle are discussed.
