Modelling turbulent combustion with finite chemical kinetics, applied to furnace off-gas combustion

This paper reports on turbulent chemical reacting flows which are generally very complex, involving interactions of chemical, thermodynamic, and fluid which mechanical processes. A combustion model based on algebraic moment closure has been developed. The model is applicable for reaction rates where the chemical kinetics can vary from slow to fast. The effects of turbulence is taken into accounts by means of modifications to the wellknown k-ε modelling procedure. The model is applied to an industrial combustion process. Calculation of furnace off-gas combustion from an aluminum reduction cell has been performed. The theoretical results agree well with experimental values
