A KINETIC STUDY OF HYDROCARBON-OXYGEN-NITROGEN FLAMES

Abstract

A comparative study was made of flame properties (burning velocities, flame front thickness and flame temperatures) in mixtures containing O and one of the following fuels; isobutane, neopentane or butane. The results indicated a correlation between the strength of the C-H bonds, and the over-all activation energies derived from burning velocities measured either at increasing dilution or at different preheating temperatures. An estimation of the mean molecular weight of chain carriers is derived from the values of the flame front thickness; the values obtained give some information about the stability of the alkyl radicals which are formed by H abstraction from the fuel molecule. An appendix contains a similar study on the ethylene oxide-O-N flames. There appears to be no essential difference between the burning of C2H4O and hydrocarbons; activation energy and molecular weight of chain carriers have normal values.
