Abstract

Soot, total hydrocarbon, oxygen and the temperature of turbulent diffusion flames together with partially premixed turbulent diffusion flames of C₃H₈ and C₂H₂, were measured under the normal temperature and pressure to study the soot formation process in a flame. To study the effect of fuel properties on the soot formation process, the soot concentration in CH₄, C₂H₂, C₂H₄, and C₂H₆ flames was also measured. The soot concentration is a flame increased along the flame axis as long as the oxygen concentration was low and the total hydrocarbon was not consumed. If the total hydrocarbon was consumed or oxygen increased, the soot concentration decreased. The maximum soot concentration in a flame was increased by increasing the flame temperature in the soot formation zone in the flame. However, if the temperature was increased beyond 1 400 K, the maximum soot concentration decreased. The maximum soot concentration was also increased by increasing the C/H ratio of the fuel.
