Fuel Nozzle Assembly Having a Premix Fuel Stabilizer

A fuel nozzle assembly (100) includes a premix chamber (114), an air flow divider extending radically and axially within the premix chamber (116) between an inner wall (102) and an outer wall (104) and a plurality of guide vanes disposed within the premix chamber (114). One or more of the guide vanes (122) includes a fuel port in fluid communication with the flow divider (116). The fuel nozzle assembly (130) further includes a premix plate (110) that extends radically between the inner and outer walls (102) (104) and circumferentially between first and second side walls (106) and (108) downstream from the fuel ports. The premix plate (110) includes an upstream side (142) axially spaced from a downstream side (144) and a plurality of passages (146) that provide for fluid flow from the premix chamber (114) through the premix plate (110). 燃料喷嘴组件(100)包括预混合室(114)、在预混合室内在内壁(102)与外壁(104)之间径向且轴向地延伸的空气流分隔件(116)、和配置在预混合室(114)内的多个引导静叶(122)。引导静叶中的个或更多个包括与流分隔件(116)流体连通的燃料端口(130)。燃料喷嘴组件(100)还包括预混合板(110)，预混合板在燃料端口(130)的下游在内
