• The effects of fuel volatility on the blow-off limit and the flame stability in spray combustion were discussed. The fuels used were gasoline, kerosene, heavy oil and C heavy oil. Every spray from an air blast atomizer used in this experiment had the same initial thrust and also had the same mean droplet diameter. The axial temperature distributions on the flame center line at the condition with and without swirl were measured. For all fuels used in this report, the fuel flow rate of blow-off limit decreased with an increasing swirl strength. At weak swirl, the fuel volatility had higher effect on the blow-off limit than at strong swirl where the recirculation zone had a higher effect on flame stability, the maximum temperature gradient decreased and the peak temperature position shifted downstream.
