2.2. Coal Properties. As reported by Chui et al., 6) it is expected that volatile yield under blast furnace tuyere and raceway conditions will be higher than in standardised proximate analysis tests due to the much higher heating rate. To account for this in the present study, a yield-adjusted coal composition of 55.6% volatile matter, 39.2% char, and 5.2% ash by mass was used as input to the ...

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.
