Study on Influence of Cavity and Water Mist on Flame Propagation of Gas Explosion in a Pipeline

For studying the influence of cavity and water mist on flame propagation gas explosion, a rectangular steel size length 80 cm × width 50 height 20 was designed. The it with explosion in large circular system 34 m studied. change pipeline analyzed. results showed that intensity velocity increase after passes through straight pipeline, attenuation rates are 4.93% -2.48%, respectively. After id="M2"> , its speed inhibited, 66.58% 45.26%, id="M3"> mist, inhibited much more, 85.09% 65.85%, is better than alone. Based theoretical analysis, concluded inhibition mainly due to repeated reflection cavity, which energy. heat absorption by vaporization.
