1. Introduction. While the Hardgrove grindability index (HGI) is a long-established test for the evaluation of coals for combustion and, compared to many of the chemical tests of coal, the equipment is cheap and relatively easy to maintain, the test is inherently inaccurate owing to the simple fact that the test fraction is generally not …Web

Pulverized coal injection (PCI) is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace (BF). Pulverized coal is an important auxiliary fuel used in the BF ironmaking. PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable.Web
