FLAME INHIBITION RESEARCH

Abstract

Composition and temperature profiles were determined for a flat methane-oxygen flame (CH4 - 0 0.078, O2 - 0.02, P equals 0.05 atm) with and without added HBr. Corrosion was so severe that the burner assembly became unusable. A new teflon-glass-ceramic system including traps to protect the pumps has been designed and is being fabricated. A program to measure the high-temperature diffusion coefficients for the analysis of the inhibited flames has been started. The apparatus has been activated and tested at 300 and 500 K on the well-known He-N2 system. Measurements have been started on the Ar-H2 system. Scavenger probe studies of radical concentrations in flames have been continued. The use of chlorinated hydrocarbons as scavenger for H atoms has been shown to be proportional to H, but the scavenging efficiency was found to be only 10%. Studies of Oatom concentration using NO2 as a scavenger were made.
