    The main cost benefit of PCI is the replacement of coking coal. The amount of coke replaced by an injected coal depends on the useable energy released by the PCI coal in the lower zone of the BF. This energy is the partial combustion heat released when coal is gasified to CO and H2 less the sensible heat of the combustion gases and ash.
