Abstract
The stabilization mechanisms of the inverted flames established in a rotating flow were investigated in order to develop a compact combustor with a high intensity and low NOx emission. The flame is sufficiently stabilized even at the equivalence ratio φ below φ=0.64 below which there is almost no production of thermal NOx because of the low temperature of the flame. The flame is also stabilized even in a high flow velocity of the mixture in the equivalence ratio φ=0.6. Therefore, the combustion of ultra low emission of NOx and high intensity can be realized by using the inverted flames established in the rotation flow.
