Explosion Venting is the most tried and tested form of eruption relief. The ignition vent panel is designed to rupture safely as a result of an over-pressure. The deflagration pressure is able to escape first through the vent opening and then into the atmosphere. This prevents the ignition from gaining momentum and having violent consequences.
The explosion panel's location is on top or side of the dust collector, process vessel, or equipment. The installation of explosion venting equipment requires professional help.
It involves using a stainless-steel panel (sometimes referred to as a vent membrane, bursting panel, or ruptured disc) and is generally fitted on silos, filters, mills, crushers, separators, extractors, collectors, and many more. In fact, any application providing the post-explosion fire can use eruption venting so that vapors can be vented to a safe area.
The most cost-effective form of ignition protection is certainly explosion venting. So before considering something as drastic as explosion suppression, it’s prudent to find out first if venting will suffice. However, if you’re unsure of your ignition protection requirements, then calling a professional will be highly beneficial.
The vented equipment links to other parts of the process specifically via ductwork. In spite of the vent panel relieving the pressure, the propagation can however return via the ductwork. For this reason, explosion isolation of ductwork should always go hand in hand with explosion venting.
