【Abstract】 This paper analyses the characteristics of the natural fameless oxidation combustor through numerical simulation. From the variation of the speed and temperature distributed in the direction of gas jet, it is found that the combustion of fameless oxidation combustor is quite steady in the mode as established in this paper. By calculation, it is shown that the temperature produced by the combustion of fameless oxidation, distributed in uniform, is much lower than that of the fame one. Hence it is concluded that the combustion of fameless oxidation can greatly reduce the NO_x formation.更多还原
