Patent number: 6675581Abstract: A premix fuel nozzle and method of operation for use in a gas turbine combustor is disclosed. The premix fuel nozzle utilizes a fin assembly comprising a plurality of radially extending fins for injection of fuel and compressed air in order to provide a more uniform injection pattern. The fuel and compressed air mixes upstream of the combustion chamber and flows into the combustion chamber as a homogeneous mixture. The premix fuel nozzle includes a plurality of coaxial passages, which provide fuel and compressed air to the fin assembly, as well as compressed air to cool the nozzle cap assembly.Type: GrantFiled: July 15, 2002Date of Patent: January 13, 2004Assignee: Power Systems MFG, LLCInventors: Peter Stuttaford, Stephen T. Jennings, Ryan McMahon, Brian R. Mack

Patent number: 6675582Abstract: A combustor liner for use in a gas turbine engine includes an annular panel section having a cooling nugget formed on one end thereof. An annular cooling lip is formed on the cooling nugget so as to define a cooling slot. The cooling lip includes a hot side, a cold side and a trailing edge surface. The hot side defines a compound taper for minimizing the thickness of the trailing edge surface. In one embodiment, the compound taper includes a first tapered surface disposed on a forward portion of the cooling lip and a second tapered surface disposed on an aft portion of the cooling lip, wherein the second tapered surface has a greater taper than the first tapered surface.Type: GrantFiled: May 23, 2001Date of Patent: January 13, 2004Assignee: General Electric CompanyInventors: Joseph Douglas Monty, John C. Jacobson

Patent number: 6675583Abstract: Upon shutdown of a liquid fuel turbine engine, the liquid fuel supply is turned off and compressed air is passed through the fuel lines and fuel injectors to purge all remaining liquid fuel into the combustion chamber to be combusted therein.Type: GrantFiled: October 2, 2001Date of Patent: January 13, 2004Assignee: Capstone Turbine CorporationInventors: Jeffrey W. Willis, Guillermo Pont, Edward C. Edelman, Gunther Linzner

Patent number: 6675584Abstract: An improved sealing device for use between a transition duct aft frame and turbine inlet is disclosed. The improved sealing device includes a plurality of corrugated metal seals that are secured to the transition duct aft frame along the arc-like sections of the aft frame. The corrugated seals contact both the transition duct aft frame and turbine inlet to provide a more effective seal and to control the amount of compressor discharge air introduced to cool the turbine vane platforms. In the preferred embodiment, the corrugated seals are coated to reduce wear, fretting, and galling and are used in conjunction with a transition duct thermally free aft frame and pivot bearing mounting system. An alternate embodiment of the seal is also disclosed that utilizes an alternate cooling hole pattern for providing additional cooling air to the turbine vane platform.Type: GrantFiled: August 15, 2002Date of Patent: January 13, 2004Assignee: Power Systems Mfg, LLCInventors: Terry L. Hollis, Gerry A. Sileo, Stephen W. Jorgensen, Robert J. Kraft, Vincent C. Martling

Patent number: 6675585Abstract: A turbomachine has inner and outer annular shells of metal material containing, in a gas flow direction F, a fuel injector assembly, a composite material annular combustion chamber, and an nozzle of metal material forming the fixed-blade inlet stage of a high pressure turbine. Provision is made for the combustion chamber to be held in position between the inner and outer metal annular shells by a plurality of flexible metal tabs having first ends interconnected by a flange-forming metal ring fixed securely to each of the annular shells by first fixing means, and second ends fixed by second fixing means firstly to the composite material combustion chamber and secondly to one end of a composite material wall whose other end forms a bearing plane for a sealing element secured to the nozzle and providing sealing for the gas stream between the combustion chamber and the nozzle.Type: GrantFiled: June 5, 2002Date of Patent: January 13, 2004Assignee: SNECMA MoteursInventors: Gwénaëlle Calvez, Eric Conete, Alexandre Forestier, Didier Hernandez

Patent number: 6675586Abstract: In a heat shield arrangement, in which heat shield elements are arranged next to one another on a carrying structure and are anchored to the carrying structure, there is provision for a cooling-air duct, into which cooling air is fed and which the adjacent heat shield elements communicate with one another, to be formed by at least two adjacent heat shield elements between the carrying structure and the surface of the heat shield elements which faces away from the hot gas. What is achieved thereby is that the individual heat shield elements are interconnected to form continuous cooling-air ducts, with the cooling air introduced into the cooling-air ducts being collected and being led, for example, to a burner. Advantageously, the gaps between the heat shield elements are sealed off by sealing elements.Type: GrantFiled: June 27, 2002Date of Patent: January 13, 2004Assignee: Siemens AktiengesellschaftInventor: Hans Maghon

Patent number: 6675587Abstract: An annular combustor suitable for use in a gas turbine engine having a plurality of fuel injectors and a plurality of apertures circumferentially arranged within the inner and outer liners of the combustion chamber is disclosed. Further, each of the apertures of the inner liner are disposed on one side of the centerline of each of the fuel injectors and each of the apertures of the outer liner are disposed on the opposing side of the centerline of each of the fuel injectors. In this way, air exhausted from the apertures advantageously opposes the direction of swirl of the fuel and air mixture that is injected from the fuel injectors thereby providing enhanced mixing of the fuel and air within the combustion chamber, increased residence time and the reduction of hot streaks in the inner and outer liners.Type: GrantFiled: March 21, 2002Date of Patent: January 13, 2004Assignee: United Technologies CorporationInventors: Charles B. Graves, Michael S. Ondas, Jason W. Norris

Patent number: 6675588Abstract: A refrigeration apparatus driven by a Stirling cooler and having reduced internal vibrations. The apparatus may include an insulated enclosure. The enclosure may define an opening from the inside to the outside. A heat-conducting member may be disposed within the enclosure and in alignment with the opening. The apparatus may further include a Stirling cooler. The Stirling cooler may be selectively connectable to the heat-conducting member. A cushioning member may be disposed between the heat-conducting member and the enclosure, such that vibrations from the Stirling cooler to the enclosure are reduced.Type: GrantFiled: March 21, 2001Date of Patent: January 13, 2004Assignee: The Coca-Cola CompanyInventor: Arthur G. Rudick

Patent number: 6675589Abstract: A freeze-crusting process and a vertical freezing apparatus preferred for use in the inventive freeze-crusting process. The freeze-crusting process preferably comprises the steps of (a) continuously delivering food products through the freezing apparatus and (b) exposing the food products to cold circulating air within the freezing apparatus in a manner effective for freezing an outermost layer of the food product. The inventive crusting process is particularly well-suited for preparing food logs and other products for slicing.Type: GrantFiled: February 20, 2003Date of Patent: January 13, 2004Inventor: David Howard
