Abstract
In order to study the effects of mass ratio of steam to biomass (mS/mB) and temperature on the gas composition, a model was developed to simulate the biomass-steam gasification process using Fluent in a fluidized bed. The simulated results showed that the volume fraction of H2 increased firstly and then remained constant with the increase of mS/mB , and that of CO decreased firstly and then got to be stable. The results indicated that the temperature benefited biomass gasification, the volume fraction of H2 and CO rised. The results of simulation basically agreed with that of experiments. Therefore, the results proved that the dynamical model could be used to simulate the biomass gasification in fluidized bed.
