The measure of the inhibition of quenched premixed flames

Abstract It is demonstrated that the measure of the inhibition of a quenched flame whose burning velocity is maintained constant (by heat transfer to a flame holder) is a rise in flame temperature on inhibition. This is in contrast to the measure of the inhibition of an adiabatic flame which is a change in burning velocity at constant temperature. This behavior is illustrated for the case of NaHCO3 inhibition of a quenched CH4/air flame, φ = 1.2, burning at 10 cm/sec.
