In this study, a separated-type small-scale biomass gasification system consisting of a pyrolyzer, a char gasifier, a combustor and a reformer with catalysts was designed. The hydrodynamic behavior of circulated particles was investigated by FLUENT 19.0 commercial software. It was observed that the c onventional non-mechanical seal internal cannot individually form a stable moving bed layer to prevent the air of riser combustor from entering into bubbling fluidized bed (BFB) char gasifier under the condition of low solids flux. To solve this problem, a seal tank wa s installed, which can direct most of air to the riser and reduce the effect of riser pressure on BFB. According to the results, the stable moving bed layer can be achieved and air of riser will not flow back in to BFB, when the seal internal and seal tank are set simultaneously
