A mathematical and numerical model of pulverized coal combustion in wide-range-use furnaces with swirl burners, i.e., within a turbulent particle-laden swirl flow in axisymmetric geometry is presented. The model is based on the k−ε model, considering the presence of the solid phase via the additional source terms in the gas phase equations. The disperse phase is treated through the history of particular particles by using the Lagrangian Stochastic Deterministic model. Devolatilization, homogeneous and heterogeneous chemical reaction processes are modeled via the global combustion model using own reaction kinetics data. The model was used to perform an analysis of influence of flow parameters and coal characteristics upon combustion in a wide-range-use furnace. The model was verified by comparing computational and experimental results for combustion of polydisperse pulverized coal in an experimental furnace.
