  • Pulverised Coal an overview ScienceDirect Topics

    Depending on speed pulverizers are classified as low-speed, medium-speed, and high-speed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace. There are two types of fuel-firing systems: bin system and direct-firing system. Coal feeders are either the volumetric or gravimetric type.Cofiring Wikipedia,Indirect co-firing systems imply usually more complex and expensive solutions, but they reduce usually problems related with corrosion, fouling, slagging, etc. This, a priori, allows co-firing rates larger than direct systems, that is, larger percentages of coal substituted by biomass or waste.
