Pulverized Coal Injection in a Blast Furnace – IspatGuru

 · 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.

 · The fineness of pulverized coal is an important indior to measure the pulverized coal quality. In terms of combustion, the fineness of pulverized coal is expected to be as small as possible to facilitate the ignition and combustion, reduce the heat loss of incomplete combustion, the amount of air supply and heat loss of exhaust smoke.
