Patent number: 8661824Abstract: An airblast fuel nozzle assembly (10) comprising a sleeve structure having a series of coaxial sleeves forming an inner-air circuit, an outer-air circuit, a main-fuel-feed circuit, and a pilot-fuel-feed circuit. The pilot-fuel-feed circuit includes a channel (44), and a discharge region (45) with exits (46). The exits (46) have a combined cross-sectional area that is substantially less than the cross-sectional area of the channel (44) upstream of the discharge region (45). In this manner, the pilot-fuel-feed circuit itself can provide a relatively large pressure drop across the channel region (44), and thereby assist in self atomization during ignition stages of engine operation.Type: GrantFiled: May 26, 2010Date of Patent: March 4, 2014Assignee: Parker-Hannifin CorporationInventors: Robert R. Pelletier, Michael K. Teter

Patent number: 8661825Abstract: A unitary fuel injection manifold for a secondary fuel nozzle improves fuel-air mixing and offers flexibility to alter the mixing profile through adaptability to a variety of number, types, and orientation of discharge outlets to the combustion air mixing space around the secondary fuel nozzle. An aerodynamic surface with reduced extension into the mixing space reduces pressures drop and interference with design airflow. Manifold integrity is enhanced by elimination of fillet welds to mount external pegs.Type: GrantFiled: December 17, 2010Date of Patent: March 4, 2014Assignee: General Electric CompanyInventors: Divyang Rajendra Desai, Sandeep Gopalakrishna, Kodukulla Venkat Sridhar, Amit Monga

Patent number: 8661827Abstract: A plate-like-object manufacturing method, plate-like objects, a gas-turbine combustor, and a gas turbine, in which degradation in the cooling performance can be suppressed, the time required for manufacturing a gas-turbine combustor can be shortened, and deterioration of the working environment can be prevented are provided. A plate-like-object manufacturing method includes a step of forming a plate-like object by stacking a plurality of plates and arranging a plurality of channels, through which a cooling medium flows, side-by-side between the plurality of plates; and a step of arranging a plurality of the plate-like objects side-by-side in a direction in which the channels are arranged, butting the plurality of plate-like objects against each other, and performing welding at an abutment section. The channels adjacent to the abutment section extend along the abutment section and have a greater dimension in the direction in which the channels are arranged, as compared with that of other channels.Type: GrantFiled: December 23, 2009Date of Patent: March 4, 2014Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Hitoshi Morimoto, Hidenori Kanki, Tatsuo Ishiguro, Hiroki Shibata, Tetsu Konishi, Kenji Sato

Patent number: 8661830Abstract: A hybrid multichannel porous structure for processing between two fluid streams of different compositions includes a housing and one or more structures disposed within the cavity of the housing in a shell and tube configuration. Each structure includes a body made of a porous, inorganic material and a plurality of channels for processing an optional sweep stream. Each channel is coated with a membrane layer. A feed stream introduced into the housing is in direct contact with the structures such that a gas selectively permeates through the body and into the channels. The gas combines with the sweep stream to form a permeate that exits from each channel. The remaining feed stream forms a retentate that exits from the housing. The feed stream may consist of syngas containing hydrogen gas and the sweep stream may contain nitrogen gas. A power plant that incorporates the hybrid structure is disclosed.Type: GrantFiled: November 2, 2009Date of Patent: March 4, 2014Assignee: General Electric CompanyInventors: Anthony Yu-Chung Ku, Kevin Paul McEvoy, Patrick Daniel Willson, Parag Parkash Kulkarni, Roger Allen Shisler, Anoop Muralidhara Kurup
