- 二次燃料供給システム(110)であって、
二次燃焼ゾーンを囲む細長い境界壁を有し、一次燃焼ゾーンと燃焼機関タービンセクションを流体的につなぐようになっている細長い移行部(116)と、
マニホルド内部と二次流体源を流体的につなぐようになっている吸込み口を具備し、前記境界壁と一体化して形成されたマニホルド(122)と、
前記マニホルド内部と前記二次燃焼ゾーンを流体的につなぐ複数の噴射ノズル(124,126)と、
非加速の二次流体流速が前記吸込み口の近くで示される前記二次流体流速の60%未満になる前記マニホルド内の位置に配置された流れ加速領域(156)と、
前記吸込み口の近くで示される前記二次流体流速の65%〜120%のレベルまで前記加速領域内の流体の流速を増すようになっている、前記流れ加速領域内に配置されたフロースリーブ(146)とを備え、そのため、マニホルド(122)内に占める前記フロースリーブ(146)の容積が前記流速を増すように定められ、
それによって前記マニホルド(122)が剛性を増し、前記移行部によって生じる振動に耐性を示すようにし、前記フロースリーブが、流れ方向において前記吸込み口から離れた領域における二次流体冷却効率の損失を補償するようにしてなり、
さらに、前記フロースリーブ(146)は、前記ノズルがそれを通って延びている開口(166)を備えた阻止帯(160)を有し、前記開口に、前記二次流体が前記ノズルの外部に沿って半径方向の外側に流れて、マニホルドの半径方向の内側境界から離れ、次に方向を変えて、前記ノズルに流入し、それを通過した後、前記マニホルドを出て、前記二次燃焼ゾーン(114)に入り込むことができるようにしてなるサイズが付与されていることを特徴とする、二次燃料供給システム。 - 前記二次流体が燃料であることを特徴とする、請求項1に記載のシステム。
- 前記二次流体にさらに希釈剤が含まれることを特徴とする、請求項2に記載のシステム。
- 前記希釈剤が蒸気であることを特徴とする、請求項3に記載のシステム。
- 希釈剤が不活性ガスであることを特徴とする、請求項3に記載のシステム。
- 前記フロースリーブは、周方向の長さが10度〜120度の範囲のスパンにわたって延びる周方向の弓状の鉢をなすことを特徴とする、請求項1に記載のシステム。
- さらに、前記移行部境界壁内の前記マニホルドに近接した領域に配置された噴出冷却孔を備えることを特徴とする、請求項1に記載のシステム。
- 前記冷却孔が、前記移行部境界壁に対して5〜45度の角度で配置されることを特徴とする、請求項7に記載のシステム。
- 前記マニホルドは、半径方向の外側カバーを有し、前記カバーは、動作中、熱応力を解放するようになっている少なくとも1つの周方向に延びるギャップを有してなることを特徴とする、請求項1に記載のシステム。
- 前記ノズルの少なくとも1つが前記マニホルドとねじ込み式に係合されることを特徴とする、請求項9に記載のシステム。
- 前記マニホルドカバーは、さらに、前記ノズルの少なくとも1つに触れることができるようにする少なくとも1つの取外し可能キャップを有することを特徴とする、請求項10に記載のシステム。
