The comparative experimental study of the porous materials suppressing the gas explosion

摘要：

The paper studied the suppression performance and mechanism of the porous materials with our designed experimental system. The experimental results showed that the wire mesh and the foam ceramic materials have a certain capability of the fire retardant and the reduction pressure. The anti-blast damage performance of the wire mesh was good but the sintering resistance performance was bad. The antiblast damage performance of the foam ceramic was bad but the sintering resistance performance was good. The absorbing sound ability of the foam ceramic was better than the wire mesh. The decay rate of the gas explosion maximum overpressure of the certain parameters wire mesh and foam ceramic for pipeline could reach 50％. The decay rate of the wire mesh for the maximum flame temperature could reach 60％ and the fire retardant effect was better than the foam ceramic.
