The combustion furnace is the central part of the combustion system for unutilized biomass such as high-water swine excrement and low-grade wood (Japanese cedar) charcoal. In the furnace, distributions of flow velocity and temperature of combustion gas are numerically simulated with the FLUENT software (ANSYS Inc.) based on the Finite Volume Method. From this CFD results including thermal radiation effect from the surface wall of the furnace, velocity distributions of magnitude and direction of combustion gas flows and temperature distributions in the furnace are shown with detailed data. Furthermore, the CFD results are verified to compare to the experimental data of combustion. he passing time of combustion gas particles through the high temperature region is sufficient to the countermeasures against dioxin.
