Flame colors in kerosene spray flames were quantitatively determined by the correlated color temperature. Detailed relations between the correlated color temperature and air ratio were investigated by using a water-cooled furnace. The heat input of an atomizing oil burner was 96 kW and the air ratio changed from 1.1 to 2.5. The results indicated that the correlated color temperature was useful to accurately express the change of flame color. The correlated color temperature ranged between 1 580 K and 2 290 K and its mean value decreased monotonously with the air ratio. Thus it was suggested that the mean value of the correlated color temperature was a good indicator of the air ratio and had the possibility to be a new information source for combustion diagnostics.
