  • Pulsed water flush of liquid fuel valves and combustion nozzles
    Patent number: 9371995
    Abstract: A method of flushing liquid fuel from valves and nozzles in a gas turbine is conducted via a mixing valve including flow passages for fuel and water. In the method, water is flowed through the flow passages, and the flow is interrupted for a period of no flow. This flow profile is repeated such that the water flow is pulsed through the flow passages.

  • FUEL SUPPLY SYSTEM
    Publication number: 20150315969
    Abstract: A fuel supply system includes a main fuel line path configured to route a fuel to a combustion inlet region and a secondary fuel line path fluidly coupled to the main fuel line path. The secondary fuel line path is configured to divert a portion of the fuel from the main fuel line path through a first segment of the secondary fuel line path and return the fuel to the main fuel line path through a second segment of the secondary fuel line path. An obstruction mechanism is located proximate the main fuel line path at an obstruction location and is configured to cyclically translate into the main fuel line path to cyclically alter a cross-sectional area of the main fuel line path to effectively oscillate fuel flow pressure into a combustion system.

  • Integrated fuel and water mixing assembly for use in conjunction with a combustor
    Patent number: 8973366
    Abstract: A system includes a mixing assembly configured to mix a liquid fuel and a water to generate a fuel mixture. The fuel mixture is configured to combust in a combustor of a gas turbine. The mixing assembly includes a liquid fuel passage disposed in an integrated housing. The liquid fuel passage is configured to flow the liquid fuel and to exclude liquid traps. The mixing assembly also includes a water passage disposed in the integrated housing. The water passage is configured to flow the water and to exclude liquid traps. The mixing assembly also includes a mixer disposed in the integrated housing and coupled to the liquid fuel passage and the water passage. The mixer is configured to mix the liquid fuel and the water to form the fuel mixture.
