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.
