Risk analysis performed on dust extraction systems.Dust explosions are said to be extraordinarily complex. Prediction of occurrence and consequence is not always possible. For the owner/operator of a manufacturing plant handling combustible com·bus·ti·ble adj. Capable of igniting and burning. n. A substance that ignites and burns readily. particulate par·tic·u·late adj. Of or occurring in the form of fine particles. n. A particulate substance. particulate composed of separate particles. solids, the best chance for success is to start with an explosion risk analysis performed by an expert in the field, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the company. This company, solely focused on explosion protection and mitigation, describes an event where proper risk analysis could have prevented or significantly reduced the damage caused by a dust explosion. A central dust extraction system was comprised of a large, filter-element dust collector with a smaller cyclone cyclone, atmospheric pressure distribution in which there is a low central pressure relative to the surrounding pressure. The resulting pressure gradient, combined with the Coriolis effect, causes air to circulate about the core of lowest pressure in a air separator on the clean air return. Shortly after startup there was a primary exlosion in the cyclone. It spread to the large filter-element dust collector. The investigation of this incident revealed that filter bags had been removed and not replaced, which led to a buildup build·up also build-up n. 1. The act or process of amassing or increasing: a military buildup; a buildup of tension during the strike. 2. of dust in the clean air parts of the dust extraction system, which was ignited by the cyclone fan.
