| Abstract Scope |
In the aluminium industry, the carbon anodes are baked in the anode baking furnace by means of the combustion of both the volatile matters emitted by the green anodes and the fuel injected. The essential objectives for baking furnaces are to achieve a uniform baking level while optimizing the fuel consumption, maintaining the refractory condition, and limiting the emissions. Those requirements are strongly influenced by the fuel injection in the heating sections, and the precise study of this phenomenon is essential to better grasp the impact of the process parameters. In this paper, a 3D model for the combustion of pulses of gas in the heating sections will be presented. This model focuses on the flame behavior in order to precisely represent the gas pulses, the quality of the combustion, the heat transfer and the emissions. The effect of the parameter variations on operation will also be presented. |
