Study on the Influence of Magnetic Metal Materials on Inhibit Gas Explosion

Abstract—In order to study the effect of magnetic metal materials on gas explosion pressure the closed explosion experiments were carried out with an independently designed explosion transient pressure test device, the explosion tests of 12% volume concentration methane-air, 5% volume concentration propane-air, and 8% volume concentration propane were carried out under the condition of installing copper, aluminum, nickel and iron metal materials. The transient pressure changes were measured and compared. The results of experiments show that: After the installing of the metal material, the peak value of the explosion pressure of the explosion is significantly reduced, indicating that the installing metal material can effectively inhibit the explosion of the combustible gas. It also can be seen that the magnetic metal materials nickel and iron have better inhibition performance than the non-magnetic metal material aluminum and copper in the gas explosion. And with the increase of the molecular weight and concentration of combustible gas, the explosion inhibition performance of magnetic metal materials become more obviously. The magnetic field effect of the magnetic metal can effectively affect the motion law of the free radicals during the explosion reaction, thus affecting the release of the explosive reaction energy.

Index Terms—Magnetic, metal material, explosion pressure, transient pressure.
