    • Pulverized Coal Injection (PCI) System for Blast

    Pulverized Coal Injection (PCI) System for Blast Furnaces In the past, reactions within the blast furnace were stimulated by injecting heavy oil, as auxiliary fuel, along with the blasts and oxygen. The heavy oil was replaced by pulverized coal after the oil crisis. This made it possible to use cheap coal,

    • 3A2. Pulverized Coal Injection for Blast Furnaces (PCI)

    2013-10-24  The injection of pulverized coal into blast furnaces in Japan began at Nippon Steel Corp.’s Oita No. 1 blast furnace in 1981. Although the main reducing material in blast furnaces is coke, blast furnace operators during and after the 1960s utilized heavyoil as a companion fuel, injecting it through the tuyeres to enhance the productivity, efficiency, and scaling up potential. After the two oil crises, however, the high price of heavy oil forced the producers to switch exclusively to coke, meaning coke was solely relied upon as the reducing material. Nevertheless, there was a desire for an inexpensive heavy-oil-alternative companion fuel to reduce costs and ensure the stable operation of blast furnaces.
