Flame front definition
WebIn this configuration, the flame is typically initiated by way of a spark within a homogeneous pre-mixture. The subsequent propagation of the developed premixed flame occurs as a spherical front until the mixture is transformed entirely or the walls of the combustion vessel are reached. Applications [ edit] WebJun 9, 2012 · The flame front diverter is used to eliminate “flame jet ignition” between the two vessels that could overpower the protection systems installed. Active devices Chemical isolation: Designed to react within milliseconds of detecting an explosion, a chemical suppression system can be installed in either inlet or outlet ducting.
