Soothing trends have been measured as a function of equivalence ratio of fuel/oxygen mixtures over the range of infinity (pure diffusion flames) to low values (double flames; an inner premixed flame and an outer diffusion flame combination). All interesting observations have been explained on the basis of changes due to oxygen addition in the fuel pyrolysis chemistry, flame structure, and interaction of double flames. This effect of oxygen addition to the fuel on soot formation has been studied in coflow and counterflow diffusion flames of ethene and propane by performing smoke height, laser light extinction, temperature, and velocity measurements.
