Pulverized coal injection is a process that involves blowing large volumes of fine coal granules into the BF. The raw material is by washing and removing the vermiculite from coal to form clean coal, which is high quality. Pulverized coal: pulverized is a technology that is a reasonable choice for blast furnace technology advancement.

PCI uses non coking coal. This coal is cheaper than the metallurgical coke. In most of the blast furnaces PCI replaces 30 to 50 % of the metallurgical coke charge. This results in lower fuel cost 2. The productivity of blast furnace improves since coal injection is accompanied with oxygen injection. 3. A wide range of coals can be injected 4.

Pulverised coal injection. Pulverised Coal Injection (PCI) technology involves injecting coal directly into the blast furnace to provide the carbon for iron-making – displacing some of the coke required for the process. A wider range of coals can be used in PCI, including steam coal which has a lower carbon content than coking coal.

Hard coking coals work best given their better coking properties, and are thus more expensive, though semi-soft coking coal and pulverized coal injections are also sometimes used. On a basic level, coke-making is carbonizing coal at high temperatures, as mentioned above, and is then heated without oxygen up to temperatures of 1100C or 2000F.
