The OH radical, the flame temperature and the pollutant emission was individually analyzed. The results show that bustion stability of diffuse swirl flame is controlled by the recirculation and diffuse mixture. The enhancement of the recirculation or the diffuse mixture can be favorable to the combustion stability. Comparing the counter-swirl, the co-swirl of fuel and air has more OH radical and heat is taken to the recirculation zone, thus this is favorable to bustion stability. When the swirl number of fuel and air is small, mixture is important to bustion stability. For counter-swirl of fuel and air, the flame is more stable than that for co-swirl more intense mixture.
