Dual fluidized-bed (DFB) has been considered as one of the most suitable technologies for biomass gasification to produce middle heating value gas free of serious dilution by N2 of combustion air and for an excellent ability to scale-up. It was well demonstrated that the dual fluidized-bed gasifier (DFBG) is a good combination of a bubbling or turbulent fluidized-bed gasifier and a riser combustor both to facilitate gasification reactions and to suppress tar formation. There are many parameters affecting the gasification system such as feedstock, geometry, circulating bed materials, operating temperature, hydrodynamics and heat transfer. The importance of the gas distributor design (critical pressure drop ratio, hole size, geometry and spacing) was addressed in the light of uniform gas distribution, bubble formation, pressure drop, dead zones, and particle attrition. Computational fluid dynamics (CFD) is a quick and cost-saving method, which can replace experimental to design the gas distributor in DFB. This project is carried out with the following objectives:
