Terence Bell. Updated on August 21, 2020. Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking. Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces.

Pulverized coal injection was developed in the 19th century, but was not implemented industrially until the 1970s. Rises in the cost of coke due to increased global demand and thus more competition for the resource have made this method attractive to the ironproducing industries and increased its value. The PCI method is based on the simple ...

Grindability Index around 80. As these coals are very easy to mill, there will be savings from reduced mill power consumption for a given coal throughput. Low volatile coal also allows the mill capacity to be increased up to 40% above that of a 50 Hardgrove Grindability Index coal, thus allowing the steelworks to increase

Before injection, coal is ground to a fine powder of around 80% < 75 μm (termed PCI pulverised coal injection) or to a granular powder of around 95% < mm (termed GCI granular coal injection). PCI is the dominant system favoured by Asian and most European steel mills but GCI has been in successful operation in British and USA mills.

About Pulverized Coal Injection (PCI): PCI is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace (BF). It is an essential instrument for modern blast furnace ironmaking. PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable.
