How do modern Flame Arresters work?

Image
  Flame arresters are non-moving passive devices. They use a wound-crimped metal ribbon-type flame cell element to prevent flame propagation from the exposed side of the unit to the protected side. This construction creates a matrix of uniform openings that are carefully designed to quench the flame by absorbing its heat. This creates an extinguishing barrier for the vapour mixture that has been ignited. The flame arrester allows a relatively free flow of gas or vapour through the piping system under normal operating conditions. If the mixture is ignited and the flame begins to return through the piping, the arrester will prevent the flame from returning to the gas source. In-line Deflagration or Detonation Flame Arrester In-line flame arresters, also known as deflagration and detonation flame arresters, are the other major category. (In layman's terms, deflagration means rapid burning and detonation means explosion.) These devices are installed in pipes to keep flames from passing...

What Is A Breather Valve? Its Advantages And Uses!

  What exactly is the Breather Valve? Breather Valve is a safety device connected to a nozzle opening over the atmospheric tank having a roof that is fixed. The valve is a type of relief valve. Its primary function is to supply adequate air flow into the tank in case the tank is out-breathing situation. It comes in a variety of forms, including pressure-only,vacuum-only, and combined pressure-and-vacuum variants. It protects storage tanks from cracks or explosion caused by the combination of vacuum and high pressure. Also, the Breather valve regulates pressure within the tank for storage. The Principles Of Operation Breather Valve Let's talk about the significance of a breather valve. The same way that the nose functions an organ for us, the same way a breather valves serve as tanks for storage. In certain circumstances tanks need to breathe or the air needs to circulate as pumps are constantly providing it. In this case it is possible for a tank to be blown out or explode if the v...

What Is A Flame Arrester And How Do They Work?

  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...
