Abstract: The developed 1-dimensional biomass gasification mathematical model [1] was validated using the experimental results obtained from a circulating fluidized bed biomass gasifier. The reactor was operated on rice husk at various equivalence ratios (ER), fluidization velocities and biomass feed rates. The model gave reasonable predictions of the axial bed temperature profile, syngas composition and lower heating value (LHV), gas production rate, gasification efficiency and overall carbon conversion. The model was also validated by comparing the simulation results with two other different size circulating fluidized beds biomass gasifiers (CFBBGs) using different biomass feedstock, and it was concluded that the developed model can be applied to other CFBBGs using various biomass fuels and having comparable reactor geometries.
