    Pulverized Coal in Blast Furnaces - MDPI

    Abstract: Pulverized coal injected into a blast furnace (BF) burns incompletely in a very limited amount of time. A considerable amount of unburned pulverized coal (UPC) escapes from the raceway to the coke layer. The unburned pulverized coal reacts with CO2 in the coke layer, and this has a very significant impact on the operation of the BF.

    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. This made it possible to use cheap coal, such as non-coking coal.
