Industrial Fire Prevention

  From our Friends at: Hazardous Engineering Solutions Explosion protection in industrial plants News    Hits: 108 Explosive atmospheres usually occur in process engineering plants such as silos, elevators, mixers, mills and conveyors. In the presence of effective internal or external ignition sources, there is a risk of explosion in the respective plant as well as a risk of propagating of the explosion into connected plant components. Explosion protection is concerned with reducing the effects of an explosion and is the central, most frequently applied explosion protection concept. The explosion protective measures include conventional explosion venting using explosion vents, flameless venting, explosion isolation and explosion suppression. But which protective measure is applied to which plant component? Plant example 1: Filters The risk of explosion is particularly high in filter systems. The very fine dust is distributed in the filter and can trigger an explosion if ...

From Chemical Processing Stop Explosion Propagation Choose a suitable method to limit damage elsewhere in the process By David Grandaw, IEP Technologies Jan 28, 2015 Industrial explosions are a constant threat to any facility that handles combustible vapors or finely divided combustible dust. Most organic material will burn in a solid form; if this same material is in a dust or vapor form, under certain conditions it will explode. Combustible dust and vapor explosions happen frequently in the processing industry. Sometimes these explosions remain confined to the process vessel in which they originate. However, more often than not, the initial explosion will result in a secondary explosion with devastating results outside the vessel or through interconnecting ducts or pipes. Flame Propagation Figure 1. Highly energetic explosions can occur in connected equipment. Having a comprehensive plan to prevent an explosion from happening under normal circumstan...
