• Impact of PCI Coal Quality on Blast Furnace Operations

  coal. The high HGI of a soft coal allows a mill to be operated at a higher mill throughput with the same or lower mill power requirement. The size distribution of the coal can impact on combustibility and coal handleability in bins and transfer lines. Blast Furnace Operation. The injected coal quality can influence the quality of the. Dust explosions explained | Characteristics, ignition and Conditions for an Explosion A dust cloud of any flammable material will explode where: 1 the concentration of dust in air falls within the explosive limits, and 2 a source of ignition of the required energy for that dust cloud is present. Conversely, an explosion can be prevented if one, or preferably both, of these conditions are avoided.
