FLAME ARRESTERS

A flame arrester, also known as a deflagration arrester or flame trap, is a device designed to allow the free flow of gas or gaseous mixtures while halting the passage of flames. It achieves this by extinguishing the flame in an array of small passages, cooling the emerging gases enough to prevent ignition on the protected side. These devices find various applications, such as being installed in combuster/burner air intakes to prevent confined and unconfined low-pressure deflagrations, halting the spread of existing explosions, and stopping potentially explosive mixtures from propagating after ignition caused by factors like lightning or static electricity. Flame arresters are commonly found in fuel storage tank vents, fuel gas pipelines, safety storage cabinets, exhaust systems of internal combustion engines, and even Davy lamps in coal mining, ensuring safety by preventing the spread of flames in hazardous environments.
