Flameless venting for bucket elevators
The Manchester, UK, division of BS&B Safety Systems is now offering a flameless venting system specifically designed as an explosion protection system for bucket elevators. The explosion venting IQR System™ comprises two parts: an explosion vent and a quenching module. The explosion vent responds rapidly to the building force of an expanding flame ball and opens to relieve this pressure. As the developing fireball passes through the vent it is intercepted by the quenching module which retains the flames and hot gases, as well as the potentially toxic burning and unburnt dust.
While the flame ball temperature of a dust explosion can easily reach 500°C/ 932°F, the quenching module typically remains below 100°C/212°F, followed by rapid cool-down due to its large surface area. This results in a negligible change in temperature in the surrounding environment. The system provides an ideal solution for venting of explosions in bucket elevators that are located within, or partially within, a building or a zoned area where normal venting cannot occur. The vents are relatively lightweight, as they are smaller than standard flameless vents. The company can provide bucket elevator examinations and guidance regarding size and position of the venting with respect to international codes and standards, including NFPA 61 or VDI 2263 Part 8.1. www.bspipd.com
