Examples of Combustible Dust : An Explosive Situation
Explosionproof pressure vessels on a dust collector can avoid the need for an isolation channel between them. In other cases, such as hammer mills, the equipment is built strong enough to withstand an explosion inside. Venting: Venting is a passive approach. The explosion vent is designed to open at a set pressure.
Explosion protection methods | Venting, suppression and containment
Explosion Suppression The alternative to explosion vent relief is explosion suppression. In their simplest form, such systems comprise a rapidacting pressure sensor, control system and a number of pressurised containers of suppressant designed for extremely rapid injection into the protected vessel. The suppressant is commonly Sodium Bicarbonate.
Prevention of GRAIN Dust ExplosionS
This primary explosion spreads the dust collected in surfaces as dust cloud or disperses within the confined space. The ignition from the primary source then ignites the dust cloud and leads to the major secondary explosion. The secondary explosion is more devastating and the magnitude of secondary explosion could destroy the facility.
