An entire utilization of alternative reducing agents inside the raceway zone is favorable to increase the coke replacement ratio in blast furnaces and utilize waste products in the ironmaking process. The extreme conditions prohibit measurements, but computational fluid dynamics incorporating validated models can help to understand the processes occurring in the raceway zone. An accurate prediction of the raceway size and shape is essential to correctly predict the thermo-chemical processes and resulting species distribution. This paper will demonstrate this based on a laboratory test setup and, furthermore, identify interstitial fluid effects to be essential to accurately predict the raceway shape.
