Abstract
Computational Fluid Dynamics models have been a precious tool to support the evolution of the Anode Baking Furnace (ABF) designs over the last 20 years. A new 3D transient model was developed for a complete fire line. This model combines the air flow characteristics with the combustion of gas and volatile matters and the heat transfers through the materials. The model results have been compared with measurement done on different furnaces with excellent outcome. It is a powerful tool to better understand the impact of different parameters, and therefore improve furnace design, performance and anode quality. For instance, it is used for modification of existing ABFs to support pot amperage creepings: implementation of higher fluewalls for longer anodes, narrower fluewalls for higher anodes, and shorter time cycle for higher production. In this article, the model will be described and some use cases will be discussed.
