Abstract: Numerical simulation which developed the mathematical model of downdraft biomass gasifier could help to understand the chemical and physical phenomena in downdraft gasifier. Also, it could help to find optimum operating conditions, design the gasifier and assist the development of new technology. The paper discussed different models available for downdraft gasifier such as thermodynamic equilibrium, chemical kinetic, computational fluid dynamics(CFD), ASPEN Plus, multiple zones models. And the single particle model was combined to the multiple zones models. The comparative analysis among the models was carried out. The results showed that the multiple zones model combined with single particle models has more broad developing prospects.

Key words: downdraft gasifier, biomass, numerical simulation
