The radiative properties of syngas mixture were calculated by weighted-sum-of-gray-gases model. The Ranz- Marshall correlation for Nusselt number was used to account for convection heat transfer between gas phase and particles. The discrete ordinates model was used for modeling of the radiative heat transfer, and the effect of ash/slag particles on radiative heat transfer was considered.
