Crimped metal ribbon flame arrester

One crimped metal ribbon flame arrester mannfactnrer has a composite element design consisting of mnltiple crimped metal ribbon elements with diverter shields (tnrbnlence-indncing devices) between the elements (Enardo n.d.). This design is based on the patent issned to Ronssakis and Brooker (1995). 

Crimped metal ribbon flame arresters are applicable for both deflagrations and detonations. They are especially used for detonations, since the apertures can be made very small, which is necessary to stop a detonation. 

Depending on the design, the pressnre drop throngh a crimped metal ribbon flame arrester may exceed that of a parallel plate type of the same size. If a crimped metal ribbon type arrester is nsed for end-of-line service... 

Protego offers a crimped metal ribbon flame arrester approved in Germany for acetylene service. It is similar in design to their flame arresters for hydrogen service bnt the hydranlic diameter of the flame arrester apertures for qnenching acetylene flames is 0.15 mm rather than 0.20 mm for hydrogen. 

It was not nndl the 1950s that detonation flame arresters made of crimped metal ribbon elements were developed and began to be used more freqnendy (Binks 1999). The major impetus for die use of crimped metal ribbon detonation flame arresters in the US was the enactment of clean air legislation (Clean Air Act of 1990) which inadvertently created a safety problem by requiring reductions in volatile organic compound (VOC) emissions. To do this, manifolded vent systems (vapor collection systems) were increasingly installed in many chemical process industry plants which captured VOC vapors and transported them to suitable recovery, recycle, or destruction systems. This emission control requirement has led to the introdnction of ignition risks, for example, from a flare or via spontaneous combustion of an activated carbon adsorber bed. Multiple... 

The crimped metal ribbon arresdng element, shown in Fignre 5-1, is one of die most widely nsed types, especially for detonadon flame arresters. Crimped metal ribbon arresters are made of alternate layers of diin corm-... 

The HSE Guide (1980) presents two equations for detonation flame speeds, one for crimped metal ribbon arresters, and one for pipes. 

Eor crimped metal ribbon arresters it provides the following equation for the maximum flame speed obtained by Cubbage (1959) for the stoppage of town gas-air mixture detonations by arresters with a crimp height of 0.017 inches ... 

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. 

Static Flame Arrester A flame arrester designed to prevent flame transmission by qnenching gaps (apertnres). These are nsnally dry type flame arresters with elements snch as crimped metal ribbon, parallel plates, wire ganze (mesh), and sintered metal.
