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.

2017-9-13  Pulverized Coal Injection (PCI) is a process that involves blowing large volumes of fine coal granules into the BF. This provides a supplemental carbon source to speed up the production of metallic iron, reducing the need for coke production. As a result energy use and emissions can be reduced. However, as coke provides physical support and gas permeability in the BF, its complete ...

About Coal – colonialcoal

From highest quality to lowest quality they are: hard coking coal, semi-soft coking coal, and pulverized coal injection (PCI) (or low volatile pulverized coal [LVPCI] injection). Met coal quality can be improved by different washing processes, but only to a certain extent as there is an inherent “coal quality.”
