Zusammenfassung:The swirl afterburning is a promising method of improving the combustion of solid fuels. The aim of the work is to verify the ANSYS CFX software package for calculating the vortex chamber of cyclone-ball furnaces afterburning. As a result of the study it was determined that to simulate the combustion of gasification products of solid fuel in a fluidized bed in a upper bed space with vortex afterburning, it is advisable to use a two-stage mechanism of methane oxidation, supplemented by hydrogen oxidation reaction. The parameters of the Eddy Dissipation model are determined, which allow obtaining results on temperature fields and fields of concentrations of the main components with satisfactory accuracy, both qualitatively and quantitatively.
