✦ Synopsis

Laminar counterflow diffusion flames of mixtures of methyl chloride and trichloroethylene with methane have been studied. Measurements of the temperature profiles were obtained through the flames, the velocity profiles, and the profiles of major species and selected minor species such as polycyclic aromatics. The critical strain rate at which flame extinction occurred was measured for a range of chlorine loading in these flames. It was found that the critical strain rate varied in an approximately linear fashion with the mole fraction of the chlorinated species in the flame. Furthermore, the results suggested that the fuel structure did not affect flame extinction greatly; the chlorine loading appeared to be the only important parameter. Measurements of minor species showed that chlorinated compounds responded more sensitively to the strain rate of the flow than other, nonchlorinated hydrocarbons.
