A model for calculating the char conversion in biomass CFB gasifiers is presented. The approach is simplified and accounts for comminution phenomena, chemical reactions and fluid-dynamics. Theoretical submodels are developed, supported by semi-empirical relations to describe fluid-dynamics and reaction within fuel particles. There is also a discussion on the type of experiments needed to estimate the main input to the model by experiments conducted in lab-scale batch-operated FB. The model is useful for implementation as a submodel in existing CFB gasification models and also as a char conversion estimator in a pseudo-equilibrium model. Keywords: gasification; circulating fluidized bed; biomass conversion
