A transient two‐dimensional mathematical model of a horizontal baking furnace is presented. The model combines complicated thermal phenomena in the baking process such as air infiltration, evolution and combustion of volatile matter; combustion of packing coke, and heat losses. The predicted results are in good agreement with measured data. Furthermore, the processes are simulated under different operating conditions such as firing cycle time, airflow and air infiltration. The simulated results indicate that the fuel consumption decreases as the firing cycle time decreases, it is also found that reducing the airflow and air infiltration will assist fuel efficiency. The model has proved to be a useful tool in the process optimization of the baking furnace in the aluminum industry.
