Pulverized Coal Injection Industrial Efficiency

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
