✦ Synopsis

If the gap between two flanges is smaller than the quenching distance no flame can propagate through the gap. but this does not prevent the ignition of an infiammable mixture following an explosion on the far side of the gap. Ignition follows entrainment of inflammable mixture into the hot jet of combustion products ejected

from the gap. The minimum size of gap through which re-ignition may occur is a function of the critical rate of entrainment into . the jet, which is estimated from the constants for the flame reaction: rate constant, B; activation energy, E; and the maximum flame temperature, Tf.
