Explosive Characteristic Of Pulverized Coal Explosion

Explosive Characteristic Of Pulverized Coal Explosion

May 10, 2013 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.Known pulverized-coal systems pulverize coal, deliver it to the fuel-burning equipment, and accomplish complete combustion in the furnace with a minimum of excess air. Accumulation of these gaseous materials may be ignited at fairly low temperatures and rapidly propagate fire or explosion. Spontaneous combustion of coal is dependent on a.
