Everything You Need to Know About Flame Arresters

A flame arrester, as the name suggests, is a device used to stop a flame from entering into an atmosphere where combustible gases may be present and prevent explosions. Gas-based equipment and appliances such as glycol dehydrators and indirect line heaters often use flame arresters. Flame arresters are also used in-line of a flare header just before the flare stack.

How Does a Flame Arrester Work?

Flame arresters consist of screens, perforated plates, and slots that are enclosed in a frame. The case helps to absorb the heat of a flame and extinguish it.
A standard flame arrester has many small tubes that help to produce the required venting capacity while preventing the passage of flame.
It works on the principle that the speed of the flame decreases with the reduction in the diameter of the pipe.
When the pipe has a very small diameter, regardless of flame speed, it is possible to prevent the passage of flame completely.

What is the Function of a Flame Arrester?

A flame arrester is commonly used for the following purposes:

Prevent an open fire from spreading
Confine the flame within an enclosed location
Protect volatile mixtures and chemicals from igniting
Stop an explosive event from spreading to other areas
Stop the flame travelling at a subsonic speed

Common Applications of Flame Arresters

They are often used with:

Line heaters, glycol dehydrator reboilers, and process heaters
Fuel storage tanks
Storage cabinets for paint, and other flammable substances
