A modeling tool has been developed for prediction of theoretical values for the main species in a syngas produced by ICFB gasification. A thermodynamic sub-model has been utilized and integrated with a simplified lumped model of the gasifier. The model predicts H2 concentration up to 61 vol. % on the water free basis. The comparison with calculations for one stage gasification demonstrates ICFB process is preferable, with no dilution by inert, nitrogen gas.The steam fuel ratio and fuel moisture exert the largest influence on hydrogen yield.
