The influence of explosion relief vent layouts on explosion
The discrete venting zones created in the silo roof are shown in Figure 1 below. The EN 14491 2012 standard was used to determine the total required vent area for a silo of this type with a P red value (the reduced overpressure, i.e. the maximum overpressure realised within the silo after the explosion relief vents have yielded) of 0.3 barg.
