Meeting explosion safety requirements with flameless venting
Flameless venting is a recently developed technology for protecting indoor equipment from dust explosions. This technology provides a ready solution for some applications where conventional explosion venting can't provide the required protection. After describing the flameless venting device and how it works, this article explains how to select a device that complies with National Fire Protection Association requirements.
Flameless venting is a relatively new dust explosion protection method for indoor equipment that combines conventional explosion venting with flame-quenching techniques. Flameless venting devices meet increasingly strict explosion safety regulations for bulk solids plants and overcome the limitations of conventional ducted explosion venting in some applications. Flameless venting devices can also be retrofitted to existing equipment installations.
