Pulverized Coal Injection (PCI) System for Blast Furnaces,

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.3A2. Pulverized Coal Injection for Blast Furnaces (PCI),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,---Jiangsu MounTop Group Co., Ltd.,Furnace coal injection technology is a new modern high ironmaking process, which that is conducive to coke production, and it helps to improve the blast furnace blast furnace smelting process and promote anterograde, its economic and social benefits significantly.
