What are flame arrestors made of?

Flame arresters: element design To go into more detail, the flame arrester element is made up of a matrix of channels the walls of which quench the flame as it passes through by removing heat energy from the reaction. (The quenching mechanism of MESG is the principal on which flame arrester elements are designed.)

How does a flame arrestor work?

A flame arrester functions by absorbing the heat from a flame front traveling at subsonic velocities, thus dropping the burning gas/air mixture below its auto-ignition temperature; consequently, the flame cannot survive. The heat is absorbed through channels (passages) designed into an element.

What is deflagration flame arrester?

In short, the deflagration Flame Arrester is designed to stop the initial phase of the explosion and is shorter and lighter than the unstable detonation arrestor, but the Deflagration Flame Arrester has restrictions on its placement within the pipework regarding distance from the source of ignition.

What is the difference between a flame arrestor and a detonation arrestor?

Vent-Line/In-Line flame arresters may be installed at some maximum distance (specified by the manufacturer) from the end of a section of open vent piping. Detonation arresters are designed so that they may be installed anywhere in a flammable vapors piping system.

Is a flame arrestor a valve?

The Valve reduces emissions and product loss, while the flame arrester protects the tank from flames in the atmosphere during venting of flammable gases.

Can flame arrestor fail?

Grossel (2002) stated that conditions exceeding the flame arrestor’s design parameters even by a small amount will lead to flame propagation past the arrestor. Roussakis (1991) stated that pressure conditions falling below the flame arrestor design point by 10% can also fail the arrestor.

Where are flame arrestors required?

Flame arrester location in the process They are usually defla- gration flame arresters, and are commonly installed on atmospheric-pressure storage tanks, process vessels, and transportation containers.

How do I choose a flame arrestor?

Flame arresters are classified according to their location relative to the equipment they are designed to protect. End-of-line flame arresters (Figure 5a) are located directly on a vessel or tank vent nozzle, or on the end of a vent line from the vent nozzle.

What is a battery flame arrestor?

What is a battery flame arrestor? A flame arrestor is a porous filter which allows battery gases to escape but prevents a flame from entering the battery. They are often made of polypropylene or polyethylene and are available in a variety of shapes.

Where is the flame arrestor on a water heater?

The flame arrestor is factory-built into the bottom of the gas tank-type water heater. It is part of the Flammable Vapor Ignition Resistant system or FVIR, together with the LDO screen and combustion chamber TCO (thermal cut off).

What is ESE lightning arrester?

The ESE Lightning Arrester, also known as Active Lightning Arrester, provide an enhanced Radius of Protection, reducing the number of Lightning Arresters and down conductors needed for your building or solar project while still providing complete protection.

What types of flame arrestors does Enardo offer?

Our portfolio includes in-line, free vent, deflagration and detonation flame arrestors. Enardo™ flame arrestors use spiral wound, crimped-metal ribbon flame cell elements to inhibit flame propagation by absorbing and dissipating heat.

What is a series 7 flame arrestor used for?

The Series 7 is typically used for end-of-line and near end-of-line applications when the system operating pressure is near atmospheric levels and when there is minimal probability of a flame stabilizing on the flame arrestor element for an extended period.

What is a bi-directional vapor arrestor?

These arrestors are bi-directional and are proven to stop an ignited flammable vapor mixture approaching from either direction and traveling at subsonic or supersonic velocities. Its flame element offers maximum flow to pressure drop characteristics.
