Influence of filling ratio on gas explosion in flameproof chamber
The maximum explosion pressure and maximum explosion pressure rate produced by different filling ratios in the flameproof chamber are different. In order to study the change characteristics of gas explosion under different filling ratios in flameproof chamber, the flameproof enclosure with a flameproof chamber size of 750 mm×750 mm×600 mm is used as ...
