Before revision: </ref> Usage and applications The uses of a flame arrester include: Stopping the spread of an open fireLimiting the spread of an already occurred explosion Preventing potentially explosive mixtures from ignitingConfining fire within a controlled location
After revision: </ref> Usage and applications The uses of a flame arrester include: Installed in Combuster/Burner air intakes with no pipe or bends before the intake to stop confined and unconfined, low pressure deflagrations, preventing an ignited atmospheric vapor cloud from propagating beyond the Flame Arrestor, outside of a burner/flare intake.Stop the spread of an already occurred explosion Preventing potentially explosive mixtures from propagating after ignition by lightning, static electricity or other sources in a vent to atmosphere.
