How Flame Arrestors Protect Tanks from Dangerous Flashbacks

What is a Flame Arrestor?

A flame arrester (also known as flame arrestor) is an important safety device used to prevent dangerous flashbacks in tanks and other closed systems. A flashback occurs when flames or explosions travel back through pipes or vents, causing an explosion or fire in a tank. Flame arrestors are designed to prevent this by extinguishing the flames or sparks before they enter the tank and cause an explosion.

How Flame Arrestors Work

Flame arrestors use a combination of mechanical and chemical methods to prevent flames and sparks from entering the tank. These devices typically consist of a series of metal plates or screens with small gaps between them. These gaps are designed to allow gas and steam to pass through, but are too small for flames or sparks. When a flashback occurs, the flames or sparks come into contact with the metal plates or screens of the flame arrestor. The plates or screens are covered with a layer of heat-resistant material and are spaced closely together to ensure that the flame is extinguished before it reaches the tank. As the flame passes through the restrictor, it is forced into a series of zigzagging paths, which reduces the flame intensity and eventually extinguishes it.

Chemical Barriers in Flame Arrestors

In addition to mechanical methods, some flame arrestors also use chemical barriers to further prevent flashback. These chemical barriers are often placed between metal plates or screens and are designed to absorb heat and extinguish the flame. This ensures that the chemical barrier provides an additional layer of protection, even if the mechanical portion of the arrestor fails.

The Importance of Flame Arrestors

The importance of flame arrestors cannot be overstated. These devices are critical in preventing dangerous explosions and fires in tanks and other closed systems. They work unobtrusively in the background, continuously protecting the tank and its contents from potential threats. In short, a flame arrestor is a specialized safety device that is essential for protecting tanks and other closed systems from flashback. These devices use a combination of mechanical and chemical measures to prevent flames and sparks from penetrating and causing dangerous explosions. Investing in a reliable flame arrestor is crucial to ensure the safety of a tank or closed system.
