In order to investigate the effects of atomization characteristics on the lean blow-out (LBO) performance, an experimental study was carried out on the spray and the combustion. The LBO limits and outlet temperatures near the LBO condition of different atomizers were measured and the combustion efficiency was estimated in a single dome rectangular model combustor with a dual-radial and a dual-axial swirl cup, respectively. The results showed that, （1） the LBO performance of the combustors with different structures and atomizers was very different. The LBO performance of the dual-radial combustors was generally better than that of the dual-axial combustors. （2）There was no obvious correlation between spray Sauter mean diameter （SMD）and LBO limit, and SMD alone cannot represent the influence of all atomization characteristics on LBO performance. （3）The hollow spray kept the flame base away from the recirculation zone, and the solid spray kept the flame base concentrated in the recirculation zone. （4）The combustion efficiency and outlet temperature of combustors with different atomization characteristics were very different near the LBO. The outlet temperature at LBO represented the ideal LBO limit. The combustion efficiency reflected the difference between the actual LBO limit and the ideal LBO limit.
