| Abstract: | In order to ascertain explosion suppression efficiency of a novel porous mineral material(Trade name: MTS)-APP powder inhibitor,a 20 L spherical explosion experimental apparatus was employed to study suppression effects of MTS,APP and their mixtures with different component proportions and added concentrations on methane-air explosion. Their pyrolysis behavior were evaluated by using a thermal analyzer. The results show that the synergistic inhibition effect of composite powder on methane explosion is most obvious when the addition of powder is 0. 100 g/L and the ratio of porous mineral to APP is 1 ∶ 3 with the weakening of each explosion parameter. Synergistic explosion suppression mechanism of MTS-APP powder consists of physical and chemical inhibition performances. The porous structure endows MTS with labyrinth effect,which enhances free radicals trapping ability. The successive endothermic decomposition reactions of MTS and APP can persistently absorb heat. Moreover,the decomposition products have the effects of dilution,cooling and isolation,and can consume the free radicals in the combustion reaction. |
