In this article, the differences between individual flame and multi-jet flames are studied. The results show that the air-blast atomization flame length is co-controlled by liquid atomization and combustion intensity. Multi-jet burner is an effective method to improve combustion intensity and shorten flame absolute length. As the oxygen velocity increased, the individual flame increased in length due to better atomization, and yet the multi-jet flame length decreased owing to better combustion intensity. A further increase in oxygen velocity had little effect on flame length but flame noises and luminosity continued to increase. The temperature gradient of the multi-jet flame was higher. An empirical formula to express the variation of the multi-jet flame length and the individual flame length was given.
