【 摘 要 】

Aiming at the goal of low pollution and high efficiency, combustion characteristics and exhaust emissions of radial staged combustor are studied using a numerical simulation method. The result shows that the combustion efficiency of staged combustor is all over 97%. The emission of pollutants, especially the CO and NOx, is obviously reduced. The advantages of staged combustor cannot be fully exploited, when the airflow is evenly distributed in the double-head. Higher combustion efficiency and lower pollutant emission can be achieved with an appropriate flow distribution ratio.
