摘要

A mathematical model of downdraft gasifier has been developed to simulate steady and transient state of gasification process. The model is based on lumped capacitance method and chemical equilibrium in pyrolysis and oxidation zone and one-dimensional reaction kinetics in reduction zone. Effects of the equivalence ratio (0.37-0.45), steam to biomass ratio (0-4) and mass flow rate of biomass (18-25 kg h(-1)) on the steady and transient characteristics of gasifier have been studied. The model gains good agreement with experimental results for exit gas composition.
