Group of problems addressed in the study is related to the aiding of numerical modelling of flow processes and combustion in the grate chambers of solid waste thermal processing equipment. In particular, the aiding comprises the following: - an innovative integration of two models: the bed combustion model and the FLUENT CFD software model, - introducing the following to the methodology of parametrization of the porous body model, which is the movable waste material layer on the grate: the porosity calculated from the author's formula for the longitudinal dispersion factor, being dependent on the grate type, operational and material parameters and their use in Ergun's equation; the permeability and Forchheimer (inertia loss) factors, as determined based on the test results and literature data, - using the flow parameters and the results of their multi-variant examination for setting down boundary conditions in the FLUENT CFD Software numerical model.
