    • 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

    • A fuel burner system (10) for a turbine engine (12) configured to operate with syngas fuel, whereby the fuel burner system (10) is configured to reduce nozzle and combustor basket temperatures is disclosed. The fuel burner system (10) may include a plurality of first and second fuel injection ports (16) positioned within a combustor (18), whereby the first fuel injection ports (14) are larger than the second fuel injection ports (16). One or more air injection ports (20) may be aligned with the first fuel injection ports (14). During operation, fuel injected into the combustor (18) from the first fuel injection ports (14) mixes better with the incoming air, causing reduced NOx emissions and lower flame temperatures. Also, the regions between adjacent air injection ports (20), which typically run the hottest, are cooler than conventional combustion system due, in part, to the smaller, second fuel injection ports (16) aligned with regions (22) between adjacent air injection ports (20).
    • 一种用于涡轮发动机(12)的燃料燃烧器系统(10),其被配置为与合成气燃料一起操作,由此燃料燃烧器系统(10)构造成减小喷嘴和燃烧器筐温度。 燃料燃烧器系统(10)可以包括定位在燃烧器(18)内的多个第一和第二燃料喷射口(16),由此第一燃料喷射口(14)大于第二燃料喷射口(16)。 一个或多个空气注入口(20)可与第一燃料喷射口(14)对准。 在操作期间,从第一燃料喷射口(14)喷射到燃烧器(18)中的燃料与进入的空气更好地混合,导致减少的NOx排放和较低的火焰温度。 另外,通常运行最热的相邻空气喷射口(20)之间的区域比传统的燃烧系统更冷,部分是由于较小的第二燃料喷射口(16)与相邻空气之间的区域(22)对准 注射口(20)。
