Abstract	Integrated gasification combined cycle (IGCC) is one of the candidates to achieve stringent environmental regulation among the clean coal technologies. Advancing the technology of the hot gas cleanup systems is the most critical component in the development of the IGCC. Thus the aim of this study is to understand the flow field in the ceramic filter and the influence of ceramic filter in removal of the particles contained in the hot gas flow. The numerical model based on the Reynolds stress turbulence model with the Darcy’s law in the porous region is adopted. It is found that the effect of the porosity in the flowfield is negligibly small while the effect of the filter length is significant. It is also found as the permeability decreases, the reattachment point due to the flow separation moves upstream. This is because the fluid is sucked into the filter region due to the pressure drop before the flow separation occurs. The particle follows well with the fluid stream and the particle is directly sucked into the filter due to the pressure drop even in the flow separation region.
