Summary:The modelling of fluid bed gasifier (FBG) units is the subject of this chapter. Approaches applied for reactor modelling, from equilibrium models to computational fluid-dynamic models, are described. The difference between gasification of biomass and coal is emphasized, underlining the impact of the fuels on the design and operation of the gasifier. The conversion of single fuel particles, char, and gas is examined to understand how sub-models are implemented in the conservation equations. Various types of commercial biomass and waste FBG units are simulated with the models presented to show their ability in predicting the performance of the gasifier.
