2020-12-1 · Understanding flame quenching is needed to develop efficient flame arresters. Here, the quenching distance of methane-air laminar flames is measured at atmospheric pressure for temperatures of the quenching surface down to the cryogenic, T w = 138 K to 293 K, for two configurations: head-on and tube quenching. Fuels or flammable mixtures in contact with surfaces at temperatures below 293 …


2020-12-1 · Flame arresters are useful devices to improve the safety of systems dealing with flammable liquids or gases such as may occur in systems that transport volatile liquid fuels. Passive flame arresters operate by absorbing heat from a flame, which, in turn, quenches chemical reactions.


A filter protects the fine mechanism against dirt. At the centre of the flashback arrestor is a hollow cylindrical filter made of sintered stainless steel. It's essential for effectively stopping a flashback. The mechanism is based on the highly porous structure of the cylindrical filter.

2017-2-26 · Flame arresters function by interrupting the combustionwave as it progresses through the ßame arrester. Typicalßame arresters accomplish this by quenching the ßame frontusing a heat sink with high surface-to-volume ratio and nar-row passageways, such as a wire screen, woven wire gauze,metal honeycomb, parallel metal plates, or a porous metalplate. The metal absorbs heat from the ßame and quenchesit, thus preventing it from passing through the ßame arrester.Various types of ßame arresters …


2016-9-1 · It implies that except the flame propagation directly through the arrestor, ignition downstream by hot products also is the mechanism by which the flame arrestor fails . Due to the transfer of heat from the flame to the crimped ribbon element, a flame is quenched with the hot products continuing to spread.
