Book Description
Modelling hydrodynamics is the first step in modelling fluidized bed combustion. This report identifies regions of characteristic hydrodynamics and delimits them according to the particle concentration profile as a basis for the three zone model. This model consists of the dense bed, the splash zone and the freeboard and also includes the effect of the presence of tubes on the extents of the zones. The two-phase flow of gas in the dense bed is examined in some detail and the flow of particles between zones and in the freeboard is discussed. Appendices give modelling details and supporting evidence for some modelling decisions.
