    • Abstract
  • Using the self-improved 20 L spherical explosion suppression experimental system, gas explosion suppression experiments on Mg(OH)2 and CO2 and both of them were studied. The results indicates that Mg(OH)2 and CO2 can suppress gas explosion. Adding Mg(OH)2 which the concentration is 250 mg/L and CO2 which the concentration is 8%, the time of the maximum explosion pressure prolongs more than three times, and the maximum explosion pressure and the maximum pressure rise rate decreased by 45.6% and 79.9%, when methane concentration is 11%. The explosion suppression effect of mixing Mg(OH)2 and CO2 is weak, compared with the effect which is added by Mg(OH)2's and CO2's.
