Flamless Vent in Action
25 ms
Pressure rise from a deflagration opens the explosion vent allowing the dust and flame to enter the flameless vent
90 ms
The flame from the deflagration makes contact with the flameless vent mesh and the quenching process begins
200 ms
The deflagration is fully quenched and begins to contract as pressure is relieved and flame is retained
500 ms
As the hot gases cool the flameless vent allows cool air to flow and the explosion is mitigated safely
