Fuel nozzle and swirler

The engine may utilize a combustor to burn fuel to drive the engine. The fuel nozzle assembly may supply fuel to the combustor for combustion or ignition of the fuel. The fuel nozzle assembly may include a swirler and a fuel nozzle to supply a mixture of fuel and air for combustion, which may supply a primary fuel supply and a secondary fuel supply. Increased efficiency and reduced emissions require the use of alternative fuels that are combusted at higher temperatures or at faster combustion speeds compared to conventional fuels, requiring improved fuel introduction without flame retention or tempering. 发动机可以利用燃烧器来燃烧燃料，以驱动发动机。燃料喷嘴组件可以将燃料供应到燃烧器，用于燃料的燃烧或点火。燃料喷嘴组件可以包括旋流器和燃料喷嘴，以供应燃料和空气的混合物，用于燃烧，其可以供应初级燃料供应和次级燃料供应。增加的效率和减少的排放需要使用替代燃料，该替代燃料与传统燃料相比，以更高的温度燃烧或者以更快的燃烧速度燃烧，需要改进的燃料引入，而不出现火焰保持或回火。
