Aluminum Dust Explosion Suppression Performance and Mechanism of a New Mesoporous Composite Explosion Suppressant. [PDF]

ACS Omega
In this paper, using a 20 L spherical explosive device and a Hartmann device, we carried out explosion suppression experiments on 19 and 30 μm aluminum powders (500 g/m3) with different concentrations of the new explosive suppressants (MCM41@CS-APP) and CaCO3 and elaborated on the suppression mechanism of the explosion of MCM41@CS-APP on aluminum ...

Different Gas Explosion Mechanisms and Explosion Suppression Techniques

Procedia Engineering, 2011
AbstractGas explosions are characterized principally in terms of two types according to the mechanism of combustion: deflagrations and detonations; detonations can be further subdivided into unstable detonations and stable detonations. All these three kinds of explosions are possible in confined underground coal mine roadways, so corresponding ...
