By controlling the temperature of sooting diffusion flames with the addition of inert additives, it was possible to show that the C/sub 4/ and C/sub 5/ olefins have the greatest tendency to soot of all the aliphatics tested - even acetylene. The results, plotted as the log of the reciprocal of the flow rate at the sooting height versus (1/T), indicate that the sooting height is a good qualitative measure of the fuel pyrolysis rate and sooting tendency. By using monoatomic and diatomic inerts, it was possible to show that fuel partial pressure was of secondary importance. Flame temperature and fuel structure appear to be the most significant factors which determine the propensity to soot in diffusion controlled combustion systems. 24 refs.
