The extended abstract gives preliminary results of exploratory tests, conducted by adding chlorine to the fuel side of a well characterized methane-air flame, to study the fundamental processes accompanying the combustion of chlorinated hydrocarbons. (NOTE: Formation of products of incomplete combustion during the thermal destruction of chlorinated compounds is of current interest.) The preliminary observations are concerned with soot emissions and flame temperature. The structure of the soot particles is examined under a scanning electron microscope (SEM). The SEM studies and the temperature measurements are compared to similar studies on a methane-air diffusion flame. Results indicate no change in the temperature field between the methane-air and chlorine/methane-air diffusion flames. The SEM analyzed soot indicated the absence of chlorine, although in one case the soot exhibited a porous structure, possibly due to chlorine induced attack.
