An experimental study has been performed on the ignition process of liquid fuel particles. The particles were ignited by propagating laminar flame. The particles arranged in a geometric configuration were installed in a combustion chamber and the combustion chamber was full of a propane-air mixture at atmospheric pressure. If the mixture was ignited, the propagating laminar flame traveled through the mixture and the liquid fuel particles were ignited by the flame. The results showed that when particle diameters were 0.55mm and 0.70mm, the ignition delays of the center particle had a local minimum. When particle diameter was 0.40mm, the ignition delay of the center particle decreased with a decrease in the particle distance. When the particle distance was long enough, the ignition delay of the center particle and that of the single particle were almost equal.
