BIOMASS GASIFICATION IN ROTATING FLUIDIZED BED

A steady-state mathematical model is developed for a rotating fluidized bed gasifier. Integrating reactor hydrodynamics with devolatilization kinetics, char gasification and combustion of both char and gas species; the model is used to present the gas-solid phenomena in novel reactor and investigates the reactor application in gasification processes. Model outputs are compared with experimental and simulation results of existing fluidized bed gasifier. It is observed that for the same equivalence ratio, the gasification process in RFB-SG is improved as a result of improved heat and mass transfer and gas-solid contact. 1
