Patent number: 9182122Abstract: A device for supplying flow across a combustor includes an axial fluid injector configured to circumferentially surround at least a portion of the combustor. An inner annular passage extends through the axial fluid injector and provides fluid communication through the axial fluid injector and into a first annular passage that surrounds the combustor. An outer annular passage extends through the axial fluid injector radially outward from the inner annular passage and provides axial flow into the first annular passage. A method for supplying flow to a combustor includes flowing a first portion of a working fluid through a first axial flow path and flowing a second portion of the working fluid through a second axial flow path.Type: GrantFiled: October 5, 2011Date of Patent: November 10, 2015Assignee: GENERAL ELECTRIC COMPANYInventors: John M. Matthews, Keith C. Belsom, Ronald James Chila

Patent number: 8443611Abstract: A system for damping combustor nozzle vibrations includes an end cover and a combustion chamber downstream from the end cover. First and second sets of nozzles extend axially between the end cover and the combustion chamber. The second set of nozzles is adjacent to the first set of nozzles. The system includes means for damping vibrations between the nozzles with a gap between the means for damping vibrations. A method for damping combustor nozzle vibrations includes flowing a working fluid through first and second sets of nozzles, wherein the first set of nozzles includes a damping member attached to and circumferentially surrounding at least a portion of the first set of nozzles, and contacting at least one nozzle in the second set of nozzles with the damping member on at least one nozzle in the first set of nozzles.Type: GrantFiled: September 9, 2011Date of Patent: May 21, 2013Assignee: General Electric CompanyInventors: Keith C.

Publication number: 20130067923Abstract: A combustor includes an end cover and a casing adjacent to the end cover, wherein the end cover and casing at least partially define a volume inside the combustor. The combustor further includes an end cap that extends radially across at least a portion of the combustor, at least one nozzle arranged in the end cap to provide fluid communication through the end cap, and means for conditioning flow through the volume. A method for conditioning flow through a combustor includes flowing a working fluid through a volume at least partially defined by an end cover, a casing, and an end cap that extends radially across at least a portion of the combustor and flowing the working fluid across an annular insert adjacent to the end cover.Type: ApplicationFiled: September 20, 2011Publication date: March 21, 2013Applicant: GENERAL ELECTRIC COMPANYInventors: Brandon Taylor Overby, Keith C.

Patent number: 6216442Abstract: In a combustor having an axis, a flow sleeve and a liner, a plurality of circumferentially spaced supports interconnect the upstream ends of the liner and flow sleeve to limit wear on the supports and accommodate relative thermal expansion of the liner and flow sleeve. Each support includes a flow sleeve stop having an angled surface, a groove and a female threaded aperture and a liner stop having a complementary angled surface, a rib and an enlarged opening. By inserting the liner axially through the open upstream end of the flow sleeve, the rib of the liner stop engages the slot of the flow sleeve stop. By passing a bolt having a spring through the enlarged opening of the liner stop and threading the bolt to the flow sleeve stop, the liner is biased for axial downstream movement to maintain the complementary inclined surfaces of the stops in contact with one another, thereby limiting wear and accommodating relative thermal expansion of the flow sleeve and liner.Type: GrantFiled: October 5, 1999Date of Patent: April 17, 2001Assignee: General Electric Co.Inventors: Keith C.

Patent number: 5785492Abstract: A stator vane assembly for a gas turbine engine is provided which includes a plurality of stator vane segments and a seal ring. Each stator vane segment has an outer platform, an inner platform, and an airfoil extending between the platforms. The stator vane segments collectively form an annular structure. The seal ring includes an abradable bearing pad which extends out from an axial surface of the body of the seal ring. The seal ring is attached to a non-rotating member within the engine, positioned in close proximity to the stator vane segments. Contact, and consequent friction, between the individual stator vane segments and the abradable bearing pad causes the abradable bearing pad to abrade, thereby creating a sealing surface reflective of the opposing stator vane segments in contact with the abradable bearing pad.Type: GrantFiled: March 24, 1997Date of Patent: July 28, 1998Assignee: United Technologies CorporationInventors: Keith C. Belsom, M. Stefan Maier
