| 20080276622 | FUEL NOZZLE AND METHOD OF FABRICATING THE SAME - A fuel nozzle includes a swirler assembly including a radially inner surface and a radially outer surface, a plurality of vanes coupled to the swirler assembly radially outer surface. Each vane includes a first sidewall and a second sidewall, the first and second sidewalls are joined at a leading edge and at an axially-spaced trailing edge, and a plurality of openings are formed through each respective vane. Each opening extends from the leading edge to the passage to define a flow passage that extends from the passage to the leading edge. A method for fabricating a fuel nozzle assembly is also described. | 11-13-2008 |
| 20090044537 | APPARATUS AND METHOD FOR EXTERNALLY LOADED LIQUID FUEL INJECTION FOR LEAN PREVAPORIZED PREMIXED AND DRY LOW NOX COMBUSTOR - A fuel injector stick for a gas turbine includes: a body of a length, L, the body including an annular shape forming a fuel channel and adapted for insertion into a premixer of the gas turbine; a mounting section for mounting the injector stick to the gas turbine; and a nozzle for injecting fuel into the premixer of the gas turbine. A gas turbine combustor and a method for changing fuel injector sticks are provided. | 02-19-2009 |
| 20100192579 | Apparatus for Fuel Injection in a Turbine Engine - In one embodiment, a system includes a fuel nozzle that includes a fuel injector configured to output a fuel flow and a premixer tube disposed about the fuel flow output from the fuel injector. The premixer tube includes a perforated portion and a non-perforated portion, and the non-perforated portion is downstream of the perforated portion. | 08-05-2010 |
| 20100223929 | SYSTEM FOR FUEL INJECTION IN A TURBINE ENGINE - In an embodiment, a system includes an end cover and a liquid cartridge. The liquid cartridge is configured to mount in a fuel nozzle of a turbine engine, wherein the liquid cartridge comprises a one piece flange configured to couple to the end cover, wherein the flange comprises a water inlet, an air inlet, and a fuel inlet. | 09-09-2010 |
| 20100313569 | Distributed-Jet Combustion Nozzle - A combustion nozzle for use in a turbine. The combustion nozzle may include a center body and a cone extending from the center body. The cone may include a number of apertures positioned therein. | 12-16-2010 |
| 20110016866 | APPARATUS FOR FUEL INJECTION IN A TURBINE ENGINE - In one embodiment, a system includes a fuel injector including a liquid fuel passage extending to a first port in a tip portion. The fuel injector also includes a selectable flow passage extending to a second port in the tip portion. The selectable flow passage surrounds the liquid fuel passage to the tip portion, the selectable flow passage is configured to selectively receive a gas fuel flow and an air flow, and the selectable flow passage has a flow temperature configured to cool a liquid fuel flowing through the liquid fuel passage to reduce coking. | 01-27-2011 |
| 20110113783 | PREMIXING APPARATUS FOR FUEL INJECTION IN A TURBINE ENGINE - In one embodiment, a system includes a fuel nozzle that includes a fuel injector that includes a fuel port and a premixer tube. The premixer tube includes a wall disposed about a central passage, multiple air ports extending through the wall into the central passage, and a catalytic region. The catalytic region includes a catalyst, disposed inside the wall along the central passage, configured to increase a reaction of fuel and air. | 05-19-2011 |
