Inhibition of Premixed C 3 H 6-AIR Flames by CH 2 (original) (raw)
The effect of gaseous CH2BrCl addition upon the characteristic parameters of combustion propagation in propyleneair mixtures in a closed vessel was investigated, at various initial pressures within 0.3-1.3 bar and various [C3H6] : [O2] and [C3H6] : [CH2BrCl] ratios. Small concentrations of added CH2BrCl (0.5-1.0 vol %) to propylene – air mixtures do not influence much the peak explosion pressures, as CH2BrCl contributes to the total amount of released heat. An important inhibiting effect of the additive is observed by means of normal burning velocities and rates of pressure rise, directly influenced by the overall reaction rate in the flame front.
