Pulverised Coal Injection (PCI) PCI for Blast Furnace method is becoming very popular globally. It is a process that involves injecting large volumes of fine coal particles into the raceway of a blast furnace (BF). This provides not only a supplemental carbon source but also speeds up the production of liquid iron besides reducing the need for metallurgical coke for reactions in the blast furnace

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

In order to reduce the cost of running blast furnaces (BFs), injected pulverized coal is used rather than coke to fire BFs. As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow and permeability of the coke column. The capacity of the furnace to consume these particles by solution loss is probably one of the limitations …

The iron making Blast Furnace is an embodiment of multitude of complex processes, which are coupled and interactive in nature. Pulverized coal (PC) has become an important auxiliary fuel for blast furnace operation since the technique of pulverized coal injection (PCI) was developed over the years. When pulverized coal is injected into blast furnaces through blowpipes and tuyeres, because of
