Explosion Protection \ Explosion Isolation
The objective of explosion isolation or decoupling is to protect adjacent parts of the plant and prevent the explosion from propagating.
In practice, many vessels, silos and devices are connected by pipes, pneumatic conveyors and dust extraction or aspiration lines. If a dust explosion occurs, the flames and pressure waves can spread through these conduits to other parts of the plant. Pre-compression and flame jet ignition exacerbate the explosion in connected vessels. The result is a series of secondary explosions that cause even more catastrophic damage.
An isolation system prevents explosions from propagating and thus minimizes the consequences of an explosion. It ensures optimum protection for adjacent parts of the plant.
