The evolution of primary soot particles (particle size distribution, number density and volume fraction) in a laminar premixed flame was investigated in this paper. It was found that all the blended flames have bimodal particle size distribution. The blending of propane greatly enhanced the nucleation of soot in the flame, and the strong continuous nucleation was also observed in the downstream of the flame. The mobility volume fraction and the number density of propane-ethylene flame are the biggest comparing to the other two flames. Calculations show that more PAHs are formed in propane-ethylene flame, resulting in the promotion of soot particles formation.
