Abstract

A thermodynamic model for an atmospheric circulating fluidized bed biomass gasifier (CFBBG) under steady state was developed in this study. Using the approach of Gibbs free energy minimization, the model was essentially independent of kinetic parameters. By introducing some non-equilibrium factors, it could be modified to predict the gasifier temperature, gas composition, lower heating value (LHV) of gas, as well as overall carbon conversion. A sensitivity analysis was performed on the model to test its response to operating variables, including equivalence ratio (ER) and biomass moisture content. The results showed that the ER has the most effect on the product gas composition and LHV. The model was validated using the experimental results obtained from a biomass demonstration power plant. A good agreement between the model predictions and experimental data was found.
