Flameless Venting Flameless Vents Euratex Ltd

And other equipment with dust explosion danger; An explosion will cause a pressure wave with a high velocity. As a result, the explosion venting device (VMP) will burst. In the meantime, the FLEX absorbs flame and burns particles. Therefore, when an explosion occurs due to the flameless vents you will only see a harmless smoke cloud.

The accepted current method of sizing is by using the nomographs in that guide, but it is also considered acceptable to ...

Dust Explosion Protection using Flameless Venting - Fike

Explosion prevention techniques attempt to minimize or eliminate the occurrence of explosions, whereas explosion protection techniques control the effects of the explosion in such a way as to minimize or eliminate the damage that could occur due to an explosion. Explosion protection techniques include containment, venting, flameless venting, isolation and suppression.

Dust Explosions Explosion Explosive Material

A dust explosion occurs when a fine dust in suspension in air is ignited, causing a very rapid burning and then the release of gaseous products with a subsequent pressure rise of explosive force that will damage plant, property and people. 6 ARCHIVE Dust explosions can be categorised into two types primary and secondary. A primary explosion ...
