Abstract: An explosion protection venting system has a plurality of vessels or reactors connected by a common vent line. A flame front diverter having a pair of opposing rupturable discs is connected to each one of a plurality of vessels for directing a deflagration away from the normal flow path and through an alternate path that prevents damage to nearby structure.

Abstract: A flame front diverter element is designed to cause a minimal pressure drop under normal venting conditions when process vapors need to pass through the explosion protection system and to other equipment connected to the manifold system. In the event of a deflagration, the flame front diverter directs the high-speed pressure wave towards a bi-directional rupturable disc causing the rupturable disc to open thus creating an aspiration effect on the opposite bi-directional rupturable disc.
