More Information
Summary:A combustor system is provided. For example, a combustor system comprises a combustor having forward and aft ends and including annular inner and outer liners that each extend generally along an axialdirection and define a combustion chamber therebetween. The combustor system also comprises a fuel nozzle having an outlet defined in an outlet end of the fuel nozzle and including a pilot swirler. The outlet is positioned at the forward end of the combustor to direct a fuel-air mixture into the combustion chamber. The combustor system further comprises a main mixer attached to the outlet end ofthe fuel nozzle and extending about the outlet. A total combustor airflow through the combustor comprises a pilot swirler airflow that is greater than about 14% of the total combustor airflow and a main mixer airflow that is less than about 50% of the total combustor airflow. 本申请提供了种燃烧器系统。举例来说，种燃烧器系统包括燃烧器，所述燃烧器具有前端和后端且包括环形内衬和外衬，所述环形内衬和外衬各自大体上沿着轴向方向延伸且在其间限定燃烧腔室。所述燃烧器系统还包括燃料喷嘴，所述燃料喷嘴具有限定在所述燃料喷嘴的出口端中的出口且包括导向旋流器。所述出口位于所述燃烧器的所述
