    • A secondary fuel delivery system for delivering a secondary stream of fuel and/or diluent to a secondary combustion zone located in the transition piece of a combustion engine, downstream of the engine primary combustion region is disclosed. The system includes a manifold formed integral to, and surrounding a portion of, the transition piece, a manifold inlet port, and a collection of injection nozzles. A flowsleeve augments fuel/diluent flow velocity and improves the system cooling effectiveness. Passive cooling elements, including effusion cooling holes located within the transition boundary and thermal-stress-dissipating gaps that resist thermal stress accumulation, provide supplemental heat dissipation in key areas. The system delivers a secondary fuel/diluent mixture to a secondary combustion zone located along the length of the transition piece, while reducing the impact of elevated vibration levels found within the transition piece and avoiding the heat dissipation difficulties often associated with traditional vibration reduction methods.
    • 公开了用于将燃料和/或稀释剂的二次流输送到位于发动机初级燃烧区域下游的内燃机的过渡件中的二级燃烧区的二次燃料输送系统。 该系统包括与过渡件一体形成并围绕过渡件的一部分的歧管,歧管入口和注射喷嘴的集合。 流量增加燃料/稀释剂流速并提高系统冷却效果。 被动冷却元件,包括位于过渡边界内的渗出冷却孔和抵抗热应力累积的热应力消散间隙,在关键区域提供补充散热。 该系统将次级燃料/稀释剂混合物输送到沿着过渡件的长度定位的二次燃烧区域,同时减少了在过渡件内发现的升高的振动水平的冲击,并避免了与传统减振方法常常相关的散热困难。
