The effects of the presence of chlorinated species on soot formation have been studied in laminar diffusion flames burning chlorinated hydrocarbons. Measurements have been made of the structure of a chlorinated laminar, diffusion flame that is stabilized in a stagnation point flow around a porous cylinder. Comparisons have been made between a pure methane flame and a flame of 50% methane and 50% methyl chloride. Temperature profiles were obtained with a thermocouple. Laser Doppler velocimetry was used to measure the velocity of the gas along the streamline. Laser extinction and scattering techniques were employed to characterize the soot aerosol. It was found that the addition of the methyl chloride to methane caused soot production, as measured by the soot volume fraction, to increase by at least an order of magnitude.
