    • Can-annular burners (50) for gas turbine engines with flow conditioners having locally varying, asymmetrical patterns of circumferential perforations, to promote uniform fuel-air mixture among all premixers (54) in the burner basket (58). Any one or more of the perforation pattern pattern density, perforation profiles and perforation cross sectional area is locally varied to alter circumferential airflow into the burner basket (52), which in turn mitigates non-uniform thru-flow variations across the burner's air inlet plane (58). In some embodiments, the flow conditioner asymmetric perforation patterns are tailored for individual burner locations within the engine's combustor section annular ring, which mitigates non¬ uniform thru-flow variation among different respective burners (50) in the combustor section annular ring. Thru-flow uniformity within each burner (50) and among all the combustor section burners (50) promotes uniform engine combustion.
    • 具有流量调节器的燃气涡轮发动机的罐环形燃烧器(50)具有局部变化的,不对称的周向穿孔模式,以促进燃烧器篮(58)中所有预混合器(54)之间的均匀的燃料 - 空气混合物。 穿孔图案图案密度,穿孔轮廓和穿孔横截面面积中的任何一个或多个被局部地改变以改变进入燃烧器篮(52)的周向气流,这进而减少穿过燃烧器的空气入口平面的不均匀通过流变化 (58)。 在一些实施例中,流量调节器不对称的穿孔图案针对发动机的燃烧器部分环形环内的各个燃烧器位置进行调整,这减轻了燃烧器部分环形环中不同的相应燃烧器(50)之间的不均匀通流变化。 每个燃烧器(50)内和所有燃烧器部分燃烧器(50)内的通流均匀性促进了均匀的发动机燃烧。

    • The subject matter of this specification can be embodied in, among other things, a fluid flow trim apparatus includes an outer housing defining a cavity having an interior surface and an end wall having an orifice therethrough, a valve body comprising a first valve portion disposed at least partly within the cavity, the first valve portion and the interior surface defining a first fluid flow path, a second valve portion in contact with the interior surface and defining a second fluid flow path. A third valve portion is disposed at least partly within the cavity between the first and second valve portions. The second fluid flow path fluidically connects the third valve portion to a trim cavity. A filter media extends from the first valve portion to the second valve portion and divides a third fluid flow path fluidically connecting the first and seconds fluid flow paths.

    • A fuel injector for injecting alternate fuels having a different energy density in a gas turbine is provided. A first fuel supply channel (18) may be fluidly coupled to a radial passage (22) in a plurality of vanes (20) that branches into passages (24) (e.g., axial passages) to inject a first fuel without jet in cross-flow injection. This may be effective to reduce flashback in fuels having a relatively high flame speed. A mixer (30) with lobes (32) for injection of a second fuel may be arranged at the downstream end of a fuel delivery tube (12). A fuel-routing structure (38) may be configured to route the second fuel within a respective lobe so that fuel injection of the second fuel takes place radially outwardly relative to a central region of the mixer. This may be conducive to an improved (e.g., a relatively more uniform) mixing of air and fuel.
    • 提供一种用于在燃气轮机中喷射具有不同能量密度的替代燃料的燃料喷射器。 第一燃料供应通道(18)可以流体耦合到多个叶片(20)中的径向通道(22),所述多个叶片分支到通道(24)(例如,轴向通道)中以在第一燃料供给通道 流动注射。 这可能有效地减少具有较高火焰速度的燃料中的回火。 具有用于喷射第二燃料的叶片(32)的混合器(30)可布置在燃料输送管(12)的下游端。 燃料路由结构(38)可以被配置为使第二燃料在相应的凸角内布置,使得第二燃料的燃料喷射相对于混合器的中心区域径向向外发生。 这可能有助于空气和燃料的改进(例如,相对更均匀)的混合。
