    Gravel Explosion Proof Fire Arrester

   

   The gravel fire arrester is a safety device used to prevent the spread of hydrogen flame outward. It consists of a solid material (fire-blocking element) capable of passing through gas with many fine channels or gaps. The gap or channel of the fire arrester is required to be as small as possible, so when the flame enters the fire arrester, the fire arrester is divided into many small flame streams, which are quenched due to heat transfer (the gas is cooled) and the wall effect.
