Coal combustion model validation using cylindrical furnace data

A computational procedure has been applied to predict two swirling pulverized coal flames in an experimental cylindrical furnace. The two fuels are different Alberta bituminous coals. The ability of available physical models, particularly those for the important devolatilization and char reaction rates, to predict mean combustor performance quantities is explored. Model recommendations are made. Comparison of the predictions for the recommended modelling with the data reveals good agreement for both coals. Sensitivities to various other model inputs are examined.
