| Abstract Scope |
In the context of carbon anodes used in aluminum production, the L/C value is a key indicator of anode quality. Higher Lc values generally mean better anode performance, which can be achieved through higher firing temperatures. But this inevitably leads to increasing NOx values in the exhaust gas from the anode furnace, which often exceed the legal limits. An optimized combination of firing technology and burner bricks can alleviate this phenomenon without provoking problems of incomplete burnout of tar volatiles, while maintaining a good temperature distribution inside the pits.
These relationships require a deep understanding of burner flame reaction kinetics and interaction of burner design and top block geometry.
This presentation sheds light on the theoretical background of these relationships and shows the improvements that have been achieved in combustion technology in recent years on the basis of CFD simulations and tests carried out on real anode furnaces. |
