A significant measure to improve cost effectiveness of the blast furnace process by reducing the coke rate was the injection of pulverized coal into the raceway of the blast furnace. For an optimal blast furnace operation using pulverized coal injection (PCI), it is necessary that the injected coal is gasified as fast and efficiently as possible within the tuyère and the raceway of the furnace.
