Abstract: CFD analysis on the MSW incinerator combustion chamber provides crucial insight into the thermal flow fields, but a difficulty arises from the boundary conditions on the waste bed in which the combustion is governed by complicated heat and mass transfer phenomena. A solid waste bed combustion model was constructed to predict the combustion process and corresponding generation of gas phase species by employing the submodels of homogeneous solid fuel particle combustion. And a strategy for simultaneous simulation of the waste bed combustion and the thermal flow fields in the furnace chamber was introduced, which would give more useful information on the effect of design and operation parameters.

Keywords: incinerator; waste bed; waste combustion; combustion chamber.
