In Line Detonation Flame Arresters

The In Line Detonation Flame Arresters are designed to prevent the propagation of gas or vapour explosions in pipelines under the most severe condition of unstable detonation. This type of arrester is specified for use in pipeline systems where the distance between the source of ignition and arrester is significant and or where detonations are also possible.

The In Line Detonation Flame Arresters (also called detonation type flanged flame arrestor) is a device fitted to the opening of an enclosure or to the connecting pipe work of a system of enclosures and whose intended function is to allow flow but prevent the transmission of flame propagating at supersonic velocity.

In Line Detonation Flame Arresters products were created in response to environmental regulations ,which required liquid product storage terminals and hydrocarbon processing plants to control evaporative hydrocarbon emissions from loading and storage operations. This process is called vapor control. Two types of recognized vapor control technologies are commonly used; carbon adsorption vapor recovery and vapor destruction or combustion. Vapor destruction systems include elevated flare systems, enclosed flare systems, burner and catalytic incineration systems, and waste gas boilers. Both systems require flame or detonation flame arresters to maximize safety. Detonation flame arresters are used in many industries, including refining, pharmaceutical, chemical, and petrochemical, pulp and paper, oil exploration and production, sewage treatment, landfills, mining, power generation, and bulk liquids transportation.

We can offer all kinds of the flame arresters, detail types as following:

* In Line Detonation Flame Arresters

* End Line flame arrester

* Special Storage Tank flame arrester* Stone flame arrester

* Suti Air flame arresting

* Drawer wave type flame arresting

* Deflagration flame arrester

* Detonation flame arrester

In-line Deflagration or Detonation Flame Arresters
The other major category consists of in-line flame arresters, also known as deflagration and detonation flame arresters. (Speaking non-technically, deflagration means rapid burning, and detonation means explosion.) These units are installed in pipes to prevent flames from passing.

Most in-line flame arrester applications are in systems which collect gases emitted by liquids and solids. These systems, commonly used in many industries, may be called vapor control systems. The gases which are vented to atmosphere or controlled via vapor control systems are typically flammable. If the conditions are such that ignition occurs, a flame inside or outside of the system could result, with the potential to do catastrophic damage.
 

One variety of vapor control systems is called vapor destruction systems. Included are elevated flare systems, enclosed flare systems, burner and catalytic incineration systems, and waste gas boilers.

Another type of vapor control system using in-line flame arresters is vapor recovery systems. Included here are vapor balancing, refrigeration, adsorption, absorption, and compression systems.

However, In Line Detonation Flame Arresters are sometimes used in end-of-line applications. For instance, an in-line unit may be mounted below a tank vent Valve on a liquid storage tank. The Valve reduces emissions and product loss, while the flame arrester protects the tank from flames in the atmosphere during venting of flammable gases.

How to selecting In Line Detonation Flame Arresters

The various dynamic states explained earlier for confined flames can be very dangerous for a process system due to the tremendous energies associated with detonation pressure and flame velocity. Things happen fast and can turn catastrophic. These multiple dynamic states increase the challenge of providing a flame arrester product or products which stop the flame and withstand the enormous pressures caused by explosions within the confined piping.

The very wide range of possible behavior for a confined flame causes two particular problems for flame arrester products. First, the high-pressure deflagration and stable detonation states have very stable kinetics of burning, and the flame is moving very fast. Therefore the arrester must be able to absorb the flame's heat much faster than is required by standard low-to-medium-pressure deflagration conditions. Second, the instantaneous impulse pressures caused by the shock waves of overdriven detonation subject the arrester to forces of up to 20995 kPa(g) (3000 psig). Thus, the arrester must be structurally superior to standard lowpressure deflagration arresters.
