    Abstract
  • To evaluate the hazard of combined gaseous epoxypropane-aluminum dust explosions, a 5 L spherical exploding device was used to measure the lower limit of explosion densities of aluminum dust in aluminum dust-air mixtures and gaseous epoxypropane-aluminum dust-air hybrid mixtures, and gaseous epoxypropane in gaseous epoxypropane-air mixtures.The results show that the existence of gas epoxypropane can reduce the lower limit of explosion density of the hybrid mixtures, and enlarge the rate of pressure rise of the hybrid mixtures; at low aluminum dust concentration, the maximum overpressures rise due to the existence of gaseous epoxypropane, and then fall with increasing aluminum dust concentration.
