A fundamental element of comprehensive pulverized-fuel combustion modelling is the description of the turbulent gaseous flow field within the furnace. As part of a program to develop a three-dimensional coal combustion code, a non-reacting gas flow dynamics model has been developed. This flow model, GAS3D, has been demonstrated in a variety of industrial configurations including corner-fired, cross-fired, and wall-fired furnace geometries. This paper discusses the components and capabilities of the model and presents comparisons between experimental data and model predictions for a wall-fired furnace. The emphasis of this paper is on evaluating model performance. Experimental data has been obtained from Consolidation Coal Company for a wall-fired furnace. This configuration has been simulated with GAS3D using three different turbulence models. A description of the flow patterns predicted within the furnace are given. Comparisons are made between the predictions and experimental data and between the different turbulence models.
