Brilex Explosion Vents or bursting discs for dust explosion relief are used in areas where a high risk of a dust explosion can occur. When selecting the areas that explosion vents can be used , one must consider various safety related factors. Explosion venting is a simple and cost effective solution for explosion protection. However, explosion vents must not be used in indoor applications unless a short duct is used to vent the contents to a safe area out doors in event of explosion or use Brilex Indoor Explosion Vents that provide safe flameless venting.
Explosion vents are commonly installed in high explosion risk zones such as filters or dust collectors/bag-houses, cyclones, silos, bins, hoppers, duct work, dryers, sifters etc. This is because a combustible dust cloud can be generated, and in combination with enough oxygen and an ignition source , a dust explosion can occur.
Explosion vents allow for the minimisation of combustion in the vented enclosure. However, they do not provide the total solution of explosion protection. Considerations such as explosion isolation due to possible flame propagation need to also be considered.
In this application , Brilex type KE explosion vents are strategically placed in ductwork. To minimise the possibility for a deflagration to turn into a detonation. By staggering explosion vents along duct work, this could be an effective means of protecting downstram equipment. Experts should be contacted to assist in the design as this setup allows the flame to continue to accelerate downstream.
