The Influence of Coke Reactivity on the Raceway Size – A Case Study (Room Virtual)

The formation of the raceway zone in the blast furnace depends on the momentum introduced by the hot blast and other alternative reducing agents and the coke consumption due to thermo-chemical conversion processes. While the influence of the introduced momentum on the raceway size has been evaluated extensively in literature, the sensitivity to the coke reactivity remains unclear. This work will evaluate the effect of the coke reactivity on the raceway size and shape using a systematic approach based on a down-scaled 2D case. The simulative case study is done with an in-house add-on to OpenFOAM®.
