A one-dimensional
unsteady state model is developed for simulation
of biomass gasification in a bubbling fluidized bed. The proposed
model accounts for the effect of hydrodynamic behavior of the fluidized
bed by incorporating the momentum equations of fluid and fuel particles.
The model results are validated against experimental data in the literature
as well as the results from existing models. The proposed model is
capable of predicting the total gas yield and composition of the product
gas at different operating conditions. The effect of biomass feeding
position is investigated, and the performance of a reactor under nonisothermal
conditions is compared with its performance under isothermal operation.
As the developed model is computationally less demanding, it can be
used to improve design and operational control of bubbling fluidized
bed gasifiers.
