| description | Fuel nozzle assemblies are provided. For example, a fuel nozzle assembly for a combustor system comprises a fuel nozzle having a pilot swirler and an outlet defined in an outlet end, as well as a mainmixer attached to the outlet end and extending about the outlet. A total combustor airflow through the combustor system comprises a pilot swirler airflow that is greater than about 14% and a main mixer airflow that is less than about 50% of the total combustor airflow. In further embodiments, the fuel nozzle also comprises main and pilot fuel injectors that each are configured to receive a portion of a fuel flow to the fuel nozzle. The fuel nozzle provides less than about 80% of the fuel flow to the main fuel injector at a high power operating condition of a gas turbine engine in which the fuel nozzle assembly is installed.
本申请提供燃料喷嘴组件。举例来说，种用于燃烧器系统的燃料喷嘴组件包括：燃料喷嘴，所述燃料喷嘴具有导向旋流器和界定在出口端中的出口；以及主混合器，所述主混合器附接到所述出口端且围绕所述出口延伸。通过所述燃烧器系统的总燃烧器气流包括大于所述总燃烧器气流的约14％的导向旋流器气流和小于所述总燃烧器气流的约50％的主混合器气流。在其它实施例中，所述燃料喷嘴还包括主燃料喷射器和导向燃料喷射器 |
