摘要
Thermochemical equilibrium modeling is the basis of the numerical method implemented in this Study to predict the performance of a biomass gasifier. To validate the model, a close agreement is shown between numerical and experimental results. The model is then used in order to optimize the selection procedure of a specific biomass for a certain application. For this purpose, the minimum and maximum amount of carbon, hydrogen, and oxygen for 55 different biomass materials are extracted to calculate the range of variation of oxygen content and carbon/hydrogen ratio. The influences of such variations on syngas characteristics are then Studied. Syngas characteristics are comprised of syngas calorific value, outlet gas temperature, gasification efficiency, and the Volume of syngas obtained. The results are plotted in a generalized format that may be used for a wide range of biomass materials. These plots can be used for the selection of a biomass material based on desired conditions. Therefore, the developed model in this Study provides a tool for design optimization of a biomass downdraft gasifier.
