Flame Arrester

In this sub-page, you will know Flame Arrester and its applications.

Flame Arrester

A flame Arrester prevents the propagation of flame but allows the flow of gas thus protecting equipment from explosive pressure.

What is a flame?

A flame is a visible spectrum of light or luminous intensity of a combustion process although some combustion process may not emit any light.

Typical applications

  • Tanks containing liquids having flash points below 110°F
  • Tanks containing liquids having flash points above 110°F
  • may sometimes need flame arrester, for example if they are surrounded by tanks containing liquids with flash points below 110°F
  • When the contents of a tank is heated to flash point
  • Lines for transferring flammable gases or vapors

The reader should also understand deflagration, detonation, and Joule-Thomson effect (why certain gases heat up in throttling expansion). For example, for hydrogen, when the operating temperature is greater than the inversion temperature, the Joule-Thomson coefficient is negative, and consequently hydrogen heats up in throttling expansion.
