20100139238 | Combustor Housing for Combustion of Low-BTU Fuel Gases and Methods of Making and Using the Same - A combustor housing includes an inlet cover plate having a central inlet configured to receive a supply of one of a high BTU content fuel or air and at least one radially-spaced, peripheral fuel inlet configured to receive a supply of a low BTU content fuel. It also includes an outlet cover plate having at least one radially-spaced, peripheral fuel outlet. The combustor housing also includes a peripheral sidewall joining the inlet cover and the outlet cover and enclosing a plenum, the at least one peripheral fuel inlet opening through the inlet cover plate into the plenum and the at least one fuel outlet opening from the plenum through the outlet cover plate. The central inlet opens into at least one conduit which extends away from the central inlet and opens into at least one high BTU content fuel conduit or air supply conduit that is axially aligned with the at least one fuel outlet. | 06-10-2010 |
20100180603 | FUEL NOZZLE FOR A TURBOMACHINE - A turbomachine includes a compressor, a turbine, and a combustor operatively connected to the turbine. The turbomachine further includes a cap member mounted to the combustor. The cap member includes a first surface and a second surface. A combustion chamber is defined within the combustor. An injection nozzle is supported at the second surface of the cap member. The injection nozzle includes a first end that extends through an inner flow path to a second end. The first end is configured to receive an amount of a first fluid and the second end is configured to receive an amount of a second fluid. A mixture of the first and second fluids is discharged from the second end of the injection nozzle. | 07-22-2010 |
20100199674 | FUEL NOZZLE MANIFOLD - A fuel nozzle manifold comprising a flange, a stem and a swirler is provided. The flange has a first fluid inlet fluidly connected to a radially extending first flow passage, the stem includes at least a first axially extending and only partially circumferentially extending flow channel, and the swirler has at least a first radially extending premix passage. The flange and the stem can comprise a homogeneous component, or two separate components fluidly connecting the first axially extending flow channel to the first flow passage, to form a fluid connection between the flange and the stem, the swirler comprises another component fitted together with the flange and stem component and fluidly connecting the first premix passage and the first flow channel. | 08-12-2010 |
20110107764 | FUEL NOZZLE ASSEMBLY FOR A GAS TURBINE ENGINE AND METHOD OF ASSEMBLING THE SAME - A method of assembling a fuel nozzle assembly for a gas turbine engine having a natural operating frequency includes providing a flange and providing a premix tube. The flange is fabricated from a first alloy such that the flange is configured to exhibit a first frequency that is different than the natural operating frequency of the gas turbine engine. The premix tube is fabricated from a second alloy such that the premix tube is configured to exhibit a second frequency that is different from the natural operating frequency of the gas turbine engine. The premix tube is coupled to the flange. | 05-12-2011 |
20110209481 | Turbine Combustor End Cover - An end cover assembly for a combustor includes a first plate receptive of one of more combustor fuel nozzles and a second plate. One or more intermediate plates are located between the first plate and the second plate and define one or more cavities to distribute fuel to one or more combustor fuel nozzles. The first plate, the second plate, and the one or more intermediate plates are secured in a stack. | 09-01-2011 |
20120308948 | COMBUSTOR NOZZLE AND METHOD FOR MODIFYING THE COMBUSTOR NOZZLE - A combustor nozzle includes a downstream surface having an axial centerline. A plurality of passages extend through the downstream surface and provide fluid communication through the downstream surface. A plurality of slits are included in the downstream surface, and each slit connects to at least two passages. A method for modifying a combustor nozzle includes machining a plurality of slits in a downstream side of a body. The method further includes connecting each slit to at least two passages that pass through the body. | 12-06-2012 |
20120322013 | Combustor Housing for Combustion of Low-BTU Fuel Gases and Methods of Making and Using the Same - A combustor housing includes an inlet cover plate having a central inlet configured to receive a supply of one of a high BTU content fuel or air and at least one radially-spaced, peripheral fuel inlet configured to receive a supply of a low BTU content fuel and an outlet cover plate having at least one radially-spaced, peripheral fuel outlet. The combustor housing also includes a peripheral sidewall joining the inlet cover and the outlet cover and enclosing a plenum, the at least one peripheral fuel inlet opening through the inlet cover plate into the plenum and the at least one fuel outlet opening from the plenum through the outlet cover plate. The central inlet opens into at least one conduit which extends away from the central inlet and opens into at least one high BTU content fuel conduit or air supply conduit that is axially aligned with the at least one fuel outlet. | 12-20-2012 |
20130209250 | TRANSITION PIECE SEAL ASSEMBLY FOR A TURBOMACHINE - A transition piece seal assembly includes a first seal, and a second seal joined to the first seal. The second seal being spaced from the first seal to define a coolant passage. | 08-15-2013 |
