Blast Furnace Operation an overviewScienceDirect Topics

Raw materials are charged to the furnace in alternating layers of coke and ore.Since the iron ore-to-coke ratio increases in a low coke operation, the coke slit in the cohesive zone becomes extremely thin, so that active usage of the gas flow in the cohesive zone is desired. This raises the question of how to increase the gas permeability.
