To provide a dual-fuel fuel nozzle that includes a center body having a tube shape and a gas fuel plenum defined within the center body.SOLUTION: The duel-fuel fuel nozzle also includes a ring manifold (126) defining a liquid fuel plenum disposed within the center body. The duel-fuel fuel nozzle further includes a plurality of radially oriented fuel injectors in fluid communication with the liquid fuel plenum. Additionally, the duel-fuel fuel nozzle includes an inner fuel tube (128) extending axially within the center body. A portion of the inner fuel tube extends helically about an axial centerline (116) of the center body. The inner fuel tube is in fluid communication with an axially oriented fuel injector. Furthermore, the duel-fuel fuel nozzle includes first fuel tube extending helically around a portion of the inner fuel tube within the center body. The first fuel tube is fluidly coupled to the fuel plenum.SELECTED DRAWING: Figure 4 【課題】管状の中心体と、中心体内に画定された気体燃料プレナムと、を含む二重燃料燃料ノズルを提供する。【解決手段】二重燃料燃料ノズルはまた、中心体内に配置された液体燃料プレナムを画定するリングマニホールド（１２６）を含む。二重燃料燃料ノズルは、液体燃料プレナムと流体連通する半径方向に配向された複数の燃料噴射器をさらに含む。さらに、二重燃料燃料ノズルは、中心体内に軸方向に延在する内側燃料管（１２８）を含む。内側燃料管の一部は、中心体の軸方向中心線（１１６）の周りに螺旋状に延在する。内側燃料管は、軸方向に配向された燃料噴射器と流体連通する。さらに、二重燃料燃料ノズルは、中心体内の内側燃料管の一部の周りに螺旋状に延在する第１の燃料管を含む。第１の燃料管は、液体燃料プレナムに流体結合される。【選択図】図４
