Studying the flame characteristics of liquid fuel atomized combustion helps to understand the entire combustion process. A new counter-flow combustor based on the technology of electro-spraying was designed. Experiment studies on electro-spraying shape and flame characteristics were carried out using alcohol as fuel. The primary focus is paid on the effects of strain rate and equivalent ratio on flame characteristics at different fuel flow rate, including flame temperatures and dimensionless diameter of the flame. The results show the boundary between atomized core regions and satellite regions of the spray gradually disappears when increasing alcohol flow rate, the liquid column of spray appears when fuel flow rate arrives 13 ml/h. The flame remains stable when the equivalent ratio is less than 1 but oscillates when the equivalent ratio is more than 1, dimensionless diameter of the flame decreases with increasing equivalent ratio. As the strain rate increases, the dimensionless diameter of the flame and the temperature decrease.
