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.

This coal is predominately sold to steel mills for use in the production of pig iron from iron ore in the blast furnace process. It is recognized as a cheaper alternative for coking coal which has been used traditionally in the blast furnace process. LV PCI coal has high content of carbon and energy but low output of ash and sulphur.

Coking coal cost surge worst for Chinese mills. In China, the surge in coking coal costs appeared to worsen, with the raw material making up between 50%70% of the input costs to produce hot metal, according to a recent market survey by Platts. A source at a steel mill in Shandong told Platts that the mill's estimated cost of coking coal had ...

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 ...
