Understanding How Flame Arresters Work

A Flame Arrester (or arrestor) is a passive devices with no moving parts, that allows hot gas to pass through, but stops a flame in order to prevent a larger fire or explosion.  Flame Arresters uses a wound metal ribbon type element that prevents the spread of flame from the exposed side of the arrester to the protected side of the arrester. The metal element's construction provides a matrix of engineered openings that are carefully calculated and sized to quench the flame by absorbing the flame's heat. As an explosion flame travels through a narrow metal space, heat is transmitted to the walls, energy is lost and only vapor gasses are able to pass through. Flame Arresters are used in many industries chemical, petrochemical, pulp and paper, refining, pharmaceutical, mining, power generation, and wastewater treatment.

Cashco Flame Arresters are specifically engineered to match the explosive mixtures Maximum Experimental Safe Gap, in order to ensure complete extinction of the flame. At the heart of each Cashco flame arrestor lies filter discs that consists of wound, smooth and channeled strips of stainless steel set at specific maximum experimental stage gaps the smaller the gaps are which the flame travels the more heat and energy is lost therefore the filters gap width and gap length are specifically engineered to match the explosive mixture in order to ensure complete extinction of the flame.
