Flame Quenching by Rectangular Channels as a Function of Channel Length for Methane-Air Mixture

Abstract

Flame quenching distance data for a thin plate forming a variable long side of multi-layer and a single rectangular channel have been obtained for a methane and air mixture. The quenching distance was affected by the channel length and the volume of the primary and secondary combustion chamber. The relation between the quenching distance G and the length of the channel L is given by where B', B, and K are constants, and e is the base of natural logarithms. It is shown that above equation may be used successfully to determine the quenching distance.
