FLAME INHIBITION RESEARCH

Abstract

A flat flame burner was set up for flame inhibition studies. The previously studied methane flame (CH4 - 0.078; O2 - 0.92; P = 0.05 atm) was successfully stabilized with added inhibitor (HBr) up to concentrations of 0.0035 mole fraction. Using the uninhibited flame, two flame composition profiles were run on the new timeof-flight mass spectrometer. A third run was made on an inhibited flame to test the sensitivity of the instrument for HBr. From these test runs it was concluded that the instrument requires the addition of a TRAP current regulator to allow quantitative work and forepump trap to shorten the HBr pump-out time. A computing machine routine for the automatic reduction of flame structure data was developed. (Author)
