  • The Potential for Dust Explosions in Dust Collection Systems

    19/01/2011  A Dust Explosion that begins in the Dust Collection System can lead to the destruction of an entire facility Most solid organic materials, in addition to many metals and inorganic nonmetallic materials, when reduced to a finely divided size, and sufficiently dispersed into the atmosphere will explode under the right conditionsA 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 highenough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygenIn cases when fuel plays the role of a combustible material, the Dust explosion Wikipedia01/01/2014  EN 14491, Dust explosion venting protective systems (2006) [3] J Taveau, Secondary dust explosions: How to prevent them or mitigate their effects, Process Safety Progress 31 (2012) 3650 [4] J Snoeys, JE Going, JR Taveau, Advances in dust explosion protection techniques: flameless venting, Procedia Engineering45 (2012) 403 413 d of the Application of Dust Explosion Protection Systems
