Experimental Research on Gas Explosion Venting of Premixed Gases in Linked Vessels
The experiment about explosion venting of methane-air mixture in linked vessels was conducted. It was compared with the single closed container explosion process. The law of pressure variation in linked vessels and the influence of gas concentration and the way of explosion venting are investigated. It was concluded that the maximum explosion pressure usually appeared at the end of the pipe. Vacuum appeared because of pressure vibration in the sphere vessel. The same as single vessel, the maximum explosion pressure appeared when the concentration of methane in the mixture was about 10 percent. Two vent ports decreased the maximum pressure in the linked vessels better than only one port. The conclusions provided scientific basis in engineering for safety design of gas explosion venting of linked vessels.
