CFD analysis of biomass steam gasification in fluidized bed gasifier

In this study, a Multi-phase CFD model based on comprehensive pyrolysis chemical reaction model was developed to simulate the gasification process of biomass. Gasification temperature and steam to biomass ratio were the main parameters studied in this work. The present study filled the gap was left by the previous studies since it was able to analyze the effect of gasification temperature and steam to biomass ratio on the gasification products of almond shells. The effect of those parameters on produced gas composition, lower heating value of the produced gas, char yield, tar content, and tar components were studied. The obtained results of the base case agree to a good extent with the results of the experiment. Besides, the obtained results of the base case were compared with another CFD study to prove the accuracy of the present model.
