“…The collision probability of free radicals with the parallel plate increased, the number of free radicals absorbed by the parallel plate increased and the number of free radicals involved in the reaction decreased, resulting in an imbalance between the heat absorbed by the parallel plate and the heat generated by combustion. [27][28][29][30][31] When the heat absorption by the parallel plate was greater than the heat release from combustion, the temperature at the front of the flame would drop below the ignition point, resulting in quenching of the flame. 32,33 The explosion pressure curves with and without parallel narrow channels in the initiating vessel and at the end of pipe are shown in Figures 4 and 5.…”

A set of experimental equipment for quenching the deflagration flame in linked vessels with parallel narrow channels was proposed. The quenching effects of the deflagration flame in the linked vessels were investigated, the influence law and mechanism of parallel narrow channels on the deflagration flame was analyzed. The results showed that the Pmax and the (dP/dt)max at each position were both lower than without parallel narrow channels, which indicated that the propagation of flame was inhibited by parallel narrow channels effectively, and the explosion intensity was also reduced. The pressure oscillation phenomenon inside the linked vessels disappeared due to the inclusion of parallel narrow channels. The deflagration flame was successfully quenched when the channel gaps were 0.5, 1.5, and 3 mm, but failed to be quenched when the channel gap was 6 mm. The quenching distance and the average propagation velocity of the deflagration flame in parallel narrow channels increased with the increase of the channel gap. When the channel gap was 6 mm, the deflagration flame completely passed through parallel narrow channels, and the average propagation velocity of deflagration flame was significantly greater than that when the deflagration flame was successfully quenched.

“…The performance of an arrestor is also affected by the size of the cross-section of apertures in the arrestor element. Equations (8)(9)(10)(11)(12)(13)(14)(15)(16)(17) and (20) show that the flameproof velocity may be inversely proportional to the aperture area. Equations (18) and (19) indicate that the flameproof is inversely proportional to the characteristic size of the cross-section.…”

Accidental explosions in gas/oil pipelines remain one major concern in process industries. The crimped ribbon flame arrestor is an effective device to prevent flame propagation. This review summarizes existing knowledge on the quenching of flame of different regimes in narrow channels and crimped ribbon flame arrestors. The influences of various parameters (e.g., arrestor element thickness, expansion ratio, system pressure) on the performance of crimped ribbon flame arrestors are discussed. The presented discussions give a better understanding on the considerations which must be taken into account to quench an explosion successfully. Other scenarios, such as quenching of two-phase vapor-liquid explosions and overdriven detonations should be got further attention. Figure 18.
