Computer Modeling of the Turbulent Natural Gas Combustion in a Cyclone-Calciner Furnace

The aim of this study is a computer modeling of the natural gasturbulent combustion in an industrial cyclonecalciner furnace. Computer modeling is performed by using Ansys Fluent computational fluid dynamics software with Reynolds-averaged Navier-Stokes (RANS) turbulence model coupled with Eddy-Dissipation concept (EDM) and discrete ordinates radiate heat transfer model. Modeling results are compared with experimental data and it's shown the influence of the mixing rate constant of EddyDissipation model on the flame temperature peaks in the furnace domain. Based on the presented results, the practical recommendations have been developed for the ANSYS Fluent software package application to industrial combustion process simulation in cyclone furnace.
