Experimental Study on Inhibiting the Gas and Coal Dust Explosion by Water Mist in Tube with Obstacle

Procedia Engineering, 2011
AbstractThe ordinary water mist has well affected on suppression and extinguishment flame, but the ability of physical extinguishment is influenced by the surrounding environment. The roadway in coal mine is very complex. So the related experiments need be considered.

Comprehensive review of multiphase flow dynamics and explosion mechanisms in hybrid combustible gas–deposited dust systems: From dust entrainment to secondary explosions

Meitan xuebao
The explosion hazards associated with hybrid combustible gas–deposited dust systems have long been posing severe safety threats to powder-processing industries. Particularly, initial explosions triggering dust entrainment readily initiate chain reactions

The Burning Velocity of Pulverised Biomass: the Influence of Particle Size

Chemical Engineering Transactions, 2016
The use of pulverised biomass as a replacement for coal in power generation is a major source of renewable electricity in the UK. However, there is little data on flame propagation rates for pulverised biomass and this makes it difficult to design ...

Experimental and Mechanistic Study of Geometric Asymmetry Effects on Gas–Coal Dust Coupling Explosions in Turning Pipelines

Symmetry
The geometric symmetry of the pipeline constitutes a critical determinant in regulating the energy propagation dynamics during the explosion process. In the present study, a transparent plexiglass pipe experimental system incorporating a range of angles (30° to 150°) was meticulously constructed.
