| 20100180600 | NOZZLE FOR A TURBOMACHINE - A turbomachine includes a compressor, a combustor operatively connected to the compressor, and an injection nozzle operatively connected to the combustor. The injection nozzle includes a main body having a first end section that extends to a second end section to define an inner flow path. The injection nozzle further includes an outlet arranged at the second end section of the main body, at least one passage that extends within the main body and is fluidly connected to the outlet, and at least one conduit extending between the inner flow path and the at least one passage. | 07-22-2010 |
| 20100180674 | Systems and Methods of Monitoring Acoustic Pressure to Detect a Flame Condition in a Gas Turbine - A method may detect a flashback condition in a fuel nozzle of a combustor. The method may include obtaining a current acoustic pressure signal from the combustor, analyzing the current acoustic pressure signal to determine current operating frequency information for the combustor, and indicating that the flashback condition exists based at least in part on the current operating frequency information. | 07-22-2010 |
| 20100280732 | METHOD FOR DETECTING GAS TURBINE ENGINE FLASHBACK - A method for monitoring and controlling a gas turbine, comprises predicting frequencies of combustion dynamics in a combustor using operating conditions of a gas turbine, receiving a signal from a sensor that is indicative of combustion dynamics in the combustor, and detecting a flashback if a frequency of the received signal does not correspond to the predicted frequencies. | 11-04-2010 |
| 20100281876 | FUEL BLANKETING BY INERT GAS OR LESS REACTIVE FUEL LAYER TO PREVENT FLAME HOLDING IN PREMIXERS - A premixer for a gas turbine combustor includes a first passage configured to inject a highly reactive fuel; and a second passage configured to inject an inert gas or a less reactive fuel or a mixture of both. The second passage is configured to form a layer of the inert gas or less reactive fuel or the mixture of both that blankets a layer of the highly reactive fuel. Another premixer includes a plurality of nozzles, each nozzle including a pair of concentric tubes, the pair of concentric tubes including a first tube configured to inject a highly reactive fuel and a second tube surrounding the first tube and configured to dispense an inert gas or a less reactive fuel or a mixture of both that blankets the highly reactive fuel. | 11-11-2010 |
| 20100287906 | FIBER-OPTIC DYNAMIC SENSING MODULES AND METHODS - A fiber-optic dynamic sensing module comprises a support member, a beam extending from the support member, and a pre-strained fiber Bragg grating sensor and a strain-free fiber Bragg grating sensor mounted on the beam. The pre-strained and strain-free fiber Bragg grating sensors each comprise a Bragg grating inscribed in a fiber. The Bragg grating of the pre-strained fiber Bragg grating sensor is packaged more tightly along a longitudinal direction of the beam than the Bragg grating of the strain-free fiber Bragg grating sensor. | 11-18-2010 |
| 20100300110 | Gas Turbine Combustion System With In-Line Fuel Reforming And Methods Of Use Thereof - A process for providing a fuel supplied to one or more combustors in a gas turbine engine system, comprising: reforming a fraction of the fuel in one or more fuel circuits of the gas turbine combustion system with a plasma reformer system to form at least one of hydrogen and higher order hydrocarbons to be supplied to the one or more combustors with a remaining fraction of the fuel; and controlling at least one of power and fuel flow to the plasma reformer system with an active feedback control system. | 12-02-2010 |
| 20110016871 | GAS TURBINE PREMIXING SYSTEMS - Methods and systems are provided for premixing combustion fuel and air within gas turbines. In one embodiment, a combustor includes an upstream mixing panel configured to direct compressed air and combustion fuel through a premixing zone to form a fuel-air mixture. The combustor also includes a downstream mixing panel configured to mix additional combustion fuel with the fuel-air mixture to form a combustion mixture. | 01-27-2011 |
