Flameless Explosion Venting
Flameless vents provide the ultimate passive solution for applications when explosion venting is not possible.
Whether a vessel is located indoors or outdoors in an occupied area, flameless venting can used to provide explosion protection without the need to worry about the flame exhaust or pressure effects. Flameless vents are a truly passive solution with no contamination effects on the process they protect.
Flameless Venting allows you to have the benefits of explosion venting without the flame exhaust
Flameless venting works by quenching the flame as it is exhausted into the flame arrestor. It eliminates the need to manage the flame exhaust while still relieving the pressure.
Timeline of Physics at Work
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
