Kuttner North America - PCI, pulverized coal injection
Blast furnaces feature pulverized coal injection (PCI) systems. The injection of up to 200 kg of coal per ton of hot metal replaces nearly the same amount of coke and, therefore, reduces production cost of the blast furnace iron. . The processing of the raw coal to injection quality is achieved in a coal grinding and drying plant.
