泡沫金属抑制瓦斯爆炸火焰的实验及机理研究
Experimental and mechanism study on gas explosion flame suppressed by foam metal
摘要
Abstract
In this paper, by using self-designed 30cm×30cm square piping experimental study on gas explosion, the new and effective gas explosive device was explored, and the barrier burst material suita-ble for use in coal mines was studied. In the tests, density of 0.3 g/cm3 foam iron-nickel metal materials were placed in the pipe, and the flame temperature data and flame size were considered together as the judgment of the target material on the explosive wave energy control. The experiment results show that 0.3g/cm3 bubble iron-nickel metal have the inhibitory effect of gas explosion flame wave and strong fire resistant capacity, and the maximum decay rate of gas explosion flame temperature in the pipe is be-tween 7.1~70.7%. Studies have also found that the thickness, diameter and substrate material composi-tion have certain influences on the inhibition effect of flame wave, and the porous foamed iron-nickel metal with high thickness, small aperture, and high nickel-containing compositions is favorable for the flame wave attenuation.关键词
