12/394544
Inventors:
William David York - Greer SC, US
Willy Steve Ziminsky - Simpsonville SC, US
Thomas Edward Johnson - Greer SC, US
Benjamin Lacy - Greer SC, US
Baifang Zuo - Simpsonville SC, US
Jong Ho Uhm - Simpsonville SC, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
F23R 3/286
US Classification:
60737
Abstract:
A fuel/air mixing disk for use in a fuel/air mixing combustor assembly is provided. The disk includes a first face, a second face, and at least one fuel plenum disposed therebetween. A plurality of fuel/air mixing tubes extend through the pre-mixing disk, each mixing tube including an outer tube wall extending axially along a tube axis and in fluid communication with the at least one fuel plenum. At least a portion of the plurality of fuel/air mixing tubes further includes at least one fuel injection hole have a fuel injection hole diameter extending through said outer tube wall, the fuel injection hole having an injection angle relative to the tube axis. The invention provides good fuel air mixing with low combustion generated NOx and low flow pressure loss translating to a high gas turbine efficiency, that is durable, and resistant to flame holding and flash back.

System And Method For Reducing Combustion Dynamics In A Combustor

View page
US Patent:
8511086, Aug 20, 2013
Filed:
Mar 1, 2012
Appl. No.:
13/409326
Inventors:
Jong Ho Uhm - Simpsonville SC, US
Thomas Edward Johnson - Greer SC, US
Baifang Zuo - Simpsonville SC, US
William David York - Greer SC, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
F02C 1/00
US Classification:
60737
Abstract:
A system for reducing combustion dynamics in a combustor includes an end cap having an upstream surface axially separated from a downstream surface, and tube bundles extend through the end cap. A diluent supply in fluid communication with the end cap provides diluent flow to the end cap. Diluent distributors circumferentially arranged inside at least one tube bundle extend downstream from the downstream surface and provide fluid communication for the diluent flow through the end cap. A method for reducing combustion dynamics in a combustor includes flowing fuel through tube bundles that extend axially through an end cap, flowing a diluent through diluent distributors into a combustion chamber, wherein the diluent distributors are circumferentially arranged inside at least one tube bundle and each diluent distributor extends downstream from the end cap, and forming a diluent barrier in the combustion chamber between at least one pair of adjacent tube bundles.

F02C 1/00
US Classification:
60772, 60737
Abstract:
A fuel injection head for a fuel nozzle used in a gas turbine combustor includes a substantially hollow body formed with an upstream end face, a downstream end face and a peripheral wall extending therebetween. A plurality of pre-mix tubes or passages extend axially through the hollow body with inlets at the upstream end face and outlets at the downstream end face. An exterior surface of the downstream end face is formed with three-dimensional surface features that increase a total surface area of the exterior surface as compared to a substantially flat, planar downstream end face.
