The Role of Flame Arrestors in Tank Vent and Relief Valve Systems

Flame arrestors play a key role in ensuring the safety of tank venting and safety valve systems. These devices are designed to prevent the spread of flames and explosions when flammable gases or vapors are present in a tank. Simply put, a flame arrestor is a safety device installed in a tank vent or safety valve system. Its main function is to stop the spread of flames by absorbing heat and cooling the flammable gases or vapors that pass through it.

How Flame Arrestors Work

There are different types of flame arrestors, but they all work in a similar way. They are constructed from a series of small, interlocking metal plates or meshes that create narrow passageways through which flammable gases or vapors can pass. These tubes have the ability to remove heat from the gas or vapor, effectively extinguishing any flames present.

Applications in Tank Venting and Safety Valve Systems

• In a tank venting system, a flame arrestor is mounted on the top of the tank to prevent flames or explosions caused by pressure changes within the tank. As the tank fills, the air and vapors inside it are displaced and must be vented. A flame arrestor prevents flames from escaping and creating potential hazards.
• Similarly, in a safety valve system, a flame arrestor is mounted at the valve outlet to prevent flames from escaping in the event of overpressure. In the event of a failure, the safety valve is activated and the flame arrestor prevents flames from spreading outside the tank.

Importance of Flame Arrestors

In addition to preventing explosions and fires, flame arrestors are also an essential safety feature of these systems. By preventing flames from escaping, they prevent thermal fires and explosions that can cause serious damage to the tank and surrounding infrastructure.

In summary, flame arrestors are key components of tank venting and safety valve systems. Not only do they prevent flames and explosions from spreading, they also ensure the safety and integrity of these systems. Periodic inspection and maintenance are necessary to ensure that these devices are operating properly and efficiently.
