What is a flame arrester?

Flame arresters , also known as flame arrestors are equipment designed to permit the passage of gases and prevent the transmission of flames. Many factors influence the eruption process like the chemical composition of the mixture, pressure waves,pre-compression, and flame propagation speed. However, thanks to advances in technology that has allowed flame arresters to be used in a variety of circumstances to stop the spread of flame and avoid massive fire explosions.

There is a fascinating story that is related with Flame arresters. The credit for discovering the that the principle of operation of flame arrestors goes directly to the late Sir Humphry Davy. He offered this revolutionary method to English mining industry, and was searching for a method to avoid the explosion of oil lamps. Sir Humphry looked into the ways in which methane ignites under various circumstances. Then, he found a way to cover the flame safely using an imposing cylinder made that was woven with a fine wire known as metal gauze in 1815.

What are the different types Of Fire Arresters?

Modern Flame arresters are divided in two different types. One is known as end-of-line and as vent-to-atmosphere flame arrester. Another is an in-line Deflagration (also known as Detonation Flame arrester. Both of them operate by the same principle. They take heat away from the flame when it tries to move through the narrow walls of steel or any other material that conducts heat. They are extensively used in various industries such as chemical, pharmaceuticals as well as petrochemicals and mining, oil production in power generation, and mining.

How do Modern Flame Arresters Work?

Flame arresters are devices that stop the spread of flame. They resemble an encased metal ribbon that regulates the flame. The system is equipped with open-ended openings that block fire by absorption of heat from the flame. This extinguisher functions as a barrier for the vapor mixture that is ignited. The flame arrester allows for the flow of vapor or gas throughout the pipe. In the event of an ignition, the flames move back into the piping. arresters stop the flame from returning towards the source of gas.

In-Line Deflagration Or Detonation Flame Arrester

In-line flame arresters are applications which collect gases released by solids and liquids. This kind of arrester is commonly used in the industrial sector and is referred to as the vapor control systems.The gasses released to the air or controlled through an Vapor control system are explosive. When the fire starts the flames will be produced, that could cause a disaster. Another kind of vapor control systems is known as the vapor destruction system. it is comprised of closed flare systems as well as the waste boilers.

In-line Deflagration may be utilized in end-of-line applications. For example, an in-line unit could be installed beneath a vent valve for a tank in a storage tank for liquids. The Valve reduces the emission and loss, and the flame arrester shields the tank from burning in the air as it vents of gasses that are flammable.

End of Line or Vent-to-Atmosphere Arrester for Flames

These arresters permit free venting along with protection against flames for vertical vents. They block the spread of flames by absorbing heat and dispersing heat by using spiral wound crimped blades of stainless steel. End-of-line flame arresters are used in vents in petroleum storage tanks.

The most common use is keeping fire from the atmosphere from getting into an enclosure. At the beginning of the 19th century, for instance there was a trend for flame arresters to be fitted at the vents of storage tanks for oil fields. They prevent the tanks from burning when the gas that flows through those vents strikes lightning.

In contrast, certain end-of-line fire arresters keep fire from the enclosure from starting an explosive atmosphere like in refineries. For example, these devices are used in furnace air intakes and exhaust stacks.
