A mathematical model of the horizontal anode baking process has been developed. The predicted results obtained are consistent and in good agreement with experimental results reported elsewhere. Several simulation runs are then made which succeed in changing the various operational parameters, such as the firing cycle time, air flow and air infiltration. The simulating results indicate that the fuel consumption decreases with the firing cycle time decreases, and it also indicates that cutting down the airflow and air infiltration will helpful for saving fuel. The model proves to be a useful tool for the optimization of the baking furnace of the aluminum industry.
