Soot Formation in Laminar Diffusion Flame

Abstract

Profiles of gas species concentration and temperature (T max: K) near the tip in normal diffusion flames of various fuel structures are measured, paying special attention to the role of reaction zone on the formation mechanism of soot precursors in the blue-violet flame. The fuels chosen for study are 1-Butene, 2-Butene, 1, 3-Butadiene, Acetylene, Allene, Benzene, Toluene, and Ethene. The sooting tendency of employed fuel becomes much highter as the Tmax is measured much lower.Toluene>Benzene>Allene>Butadiene>Acetylene>Ethene.It show that sooting tendency due to fuels is independent of the initial fuel concentration from the measured results of temperature.
