Summary:PROBLEM TO BE SOLVED: To provide an axial fuel staging (AFS) system that can improve the overall operating efficiency of a combustor of a gas turbine.SOLUTION: A fuel injector 204 includes a manifold 220 and a housing 212 coupled to the manifold. The housing defines an interior chamber 254 therein. The fuel injector also includes a nozzle 210 positioned within the interior chamber. The nozzle includes an array 230 of mixing tubes 232 that each have a proximal end 234, a distal end 236, and a perforated body 238 extending therebetween. The proximal ends are coupled in flow communication with the manifold such that perforations 246 of each body are in flow communication with the interior chamber to facilitate discharging a mixture of fuel and compressed gas from the distal ends.SELECTED DRAWING: Figure 3 【課題】ガスタービンの燃焼器の作動効率を、全体的に向上させることが可能な軸方向燃料ステージング（ＡＦＳ）システムを提供する。【解決手段】燃料噴射装置２０４は、マニホールド２２０と、このマニホールドに連結されたハウジング２１２とを備える。このハウジングは内部チャンバ２５４を画定している。また、本燃料噴射装置は、内部チャンバ内に配置されたノズル２１０を備える。このノズルは、各々が近位端部２３４と、遠位端部２３６と、これらの間に延びる多孔本体２３８とを有する混合管２３２のアレイ２３０を備える。各本体の穿孔部２４６が内部チャンバと流体連通して、燃料と圧縮ガスとの混合物を遠位端部から排出しやすくするように、近位端部をマニホールドと流体連結している。【選択図】図３
