摘要： Casting method and cast manifold are provided. The method allows configuring conduits, such as conduits (46, 48) in a fuel feed boss (20) and/or a base rocket (13), which are part of the manifold for removing a ceramic core (44) from the cast without forming extraneous holes in the body of the manifold. Absence of such extraneous holes in turn allows eliminating sealing plugs and welds, which otherwise would be needed for sealing the extraneous holes.

摘要： An improved interface (111) between a combustion basket ring and a transition assembly (113) in a can-annular gas turbine engine. Traditionally, a spring clip is positioned within a circumferential gap between a combustion basket ring and the transition assembly such that a gas flow across the interface experiences a radial offset based on the circumferential gap. The improvement includes a flared inlet end (140) of the transition duct (114) to eliminate the radial offset of the gas flow (116) across the interface (111). A transition assembly (113) is provided including a transition inlet ring (120) and the transition duct (114) with the flared inlet end (140).

摘要： A system and method for sensing and monitoring gaseous emissions in a combustion turbine engine are provided. The system includes one or more sensors (12) configured to generate a signal indicative of concentration of emissions in a flue gas, such as may be produced in a combustor of a combustion turbine engine. In certain disclosed embodiments, a controller (20) may be coupled to receive the signal indicative of the concentration of emissions. Controller (20) may be further coupled to receive a signal indicative of a condition of combustor dynamics to generate a combustion control signal based on a combustion control strategy responsive to the concentration of emissions and the condition of combustor dynamics. This control strategy that can integrate practically in real-time knowledge of emissions conditions and combustor dynamics conditions is expected to improve control of emissions and combustor dynamics.

摘要： 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.

摘要： A transition-to-turbine seal assembly is provided. Seal members (52, 58) may include one or more anchoring tabs (54, 60) affixed only to an associated transition (56) and not to a neighboring transition (57). Thus, seal members (52, 58) may be practically free from high stress levels due to differing motion that can arise between neighboring transitions (56, 57). Additionally, seal members (100, 120) may include articulating segments (106, 108, 126, 128) arranged to provide a respective degree of freedom along a desired direction.
