Dust explosion - Wikipedia

19 行· A 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 fuelDust Explosion - an overview | ScienceDirect Topics,Dust explosions can result in very significant property damage and serious injuries to personnel. Combustible dusts are defined as: “A combustible particulate solid that presents a fire or explosion hazard when suspended in air or the process-specific oxidizing medium over a range of concentrations, regardless of particle size or shape.”Dust explosions explained | Characteristics, ignition and,,Characteristics of Dust Explosions When a mass of solid flammable material is heated it burns away slowly owing to the limited surface area exposed to the oxygen of the air. The energy produced is liberated gradually and harmlessly because it is dissipated as quickly as it is released. The result is quite different if the same mass of material is ground to a fine powder and intimately mixed,
