Quenching diameter, flame arrester

Whether a flame is transmitted through a flame arrester depends on the length and aperture size of the arrester, the approach velocity of the flame, the pressure rise, and the temperature of the arrester (Wilson and Flessner 1978). Wilson and Flessner state that the evidence indicates that low-speed flames can be quenched by an array of small passageways placed in a duct, provided that the effective passageway diameter (critical diameter) meets the following criterion ... 

Crimped Metal Ribbon A flame arrester element that is manufactured of alternate layers of thin corrugated metal rihhon and a flat metal rihhon that are wound together on a mandrel to form a cylindrical assembly of many layers to produce a range of different sized triangular cells. The height and width of the triangular cells can he varied to provide the required quenching diameter.
