Understanding Industrial Flame Arrestors

Flame Arrestor
A flame arrestor operates by removing heat from the flame as it attempts to travel through narrow passages with heat-conductive walls. The arrester will stop a high velocity flame by absorbing heat away from the flame head, which lowers the burning gas/air mixture below its auto-ignition temperature, and creating an atmosphere where the flame cannot be sustained. The channels or passages in the flame arrester are designed to very efficiently conduct heat outward, but still allow the gasses to flow.

The document below, courtesy of ENARDO, provides a nicely detailed explanation of flame arrestor technology as well as where and how they are used.

Finally, its always a wise decision to consult with an experienced applications specialist when choosing, specifying, or applying any type of flame arrestor.
