摘要： A flow control device for a combustor is provided in which the flow control device comprises a shroud having a first end and a second end wherein the second end is coupled to the combustor. The shroud is disposed to receive a primary fluid and disposed to direct the primary fluid into the combustor. In addition, the shroud further comprises a plurality of ports disposed therein wherein the ports are oriented to extract a portion of a flow from a flow path of the primary fluid so as to control a flow rate of the primary fluid through the shroud.

摘要： A method for providing cooling air to the venturi and the combustion chamber in a low NOx emission combustor as used in a gas turbine engine that includes the steps of providing an annular air passage surrounding said combustion chamber and venturi where said cooling air under pressure enters the combustion chamber/venturi near the aft portion of the combustion chamber, passing the air along the combustion chamber, past the venturi where the air exits near the front portion of the convergent area of the venturi. The method prevents any channel/passage cooling air from being received into the combustion chamber, and at the same time, introduces the outlet of the cooling air, after the air has passed over the combustion chamber of the venturi and has been heated, back into the premix chamber thereby improving the efficiency of the combustor while reducing and lowering NOx emission in the combustion process. In an alternate embodiment, a combustion system is disclosed incorporating a shaped deflector to direct cooling air into a cooling passageway of a venturi. The deflector is configured to provide a cooling system with increased total pressure to increase overall cooling effectiveness.
摘要翻译：一种用于在燃气涡轮发动机中使用的低NOx排放燃烧器中的文丘里管和燃烧室的冷却空气的方法，该方法包括以下步骤：提供围绕所述燃烧室和文丘里管的环形空气通道，其中所述压力下的冷却空气进入在燃烧室的后部附近的燃烧室/文丘里管，沿着燃烧室使空气通过文丘里管，其中空气在文丘里管的会聚区域的前部附近离开。该方法防止任何通道/通道冷却空气被接收到燃烧室中，并且同时在空气已经经过文丘里管的燃烧室并且被加热之后引入冷却空气的出口从而提高了燃烧器的效率，同时降低和降低了燃烧过程中的NOx排放。在替代实施例中，公开了一种结合成形偏转器以将冷却空气引导到文氏管的冷却通道中的燃烧系统。偏转器被配置为提供具有增加的总压力的冷却系统以增加总体冷却效果。

摘要： A one-piece deflector-flare cone assembly for a gas turbine engine combustor that facilitates extending a useful life of the combustor in a cost-effective and reliable manner is described. The one-piece assembly includes a deflector portion and a flare cone portion. The deflector portion includes an integral opening that extends through the deflector portion for receiving cooling fluid therein. The cooling opening extends circumferentially within the deflector portion. Cooling fluid discharged from the cooling opening is used for impingement cooling a portion of the flare cone portion to facilitate reducing an operating temperature and extending a useful life of the combustor.
