Coal Mill Dust Explosion

  • Dust explosion Wikipedia
    OverviewTerminologyConditions requiredMechanismEffectsProtection and mitigationA dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygen. In cases when fuel plays the role of a combustible material, the explosion is known as a fuel-air explosion. Dust explosions are a frequent hazard in coal mines, grain elevators, and other industrial
