Fuel Structure and Pressure Effects on the Formation of Soot Particles in Diffusion Flames

Abstract

Studies emphasizing the effects of fuel molecular structure on soot formation processes in laminar diffusion flames have been investigated. Particular attention has been given to the particle inception and surface growth processes for a series of fuels. Studies of butane, 1-butene and 1,3 butadiene have revealed that fuel structure strongly affects the soot particle inception process. However, subsequent surface growth processes are largely determined by the available surface area. Thus, the surface growth process is independent of the fuel molecular structure following the initial particle inception stage. Studies of the particle inception region indicate that increased soot formation is strongly correlated with visible fluorescence measurements attributed to large polynuclear aromatic hydrocarbon species in the flame.
