  • SYSTEMS AND METHODS TO MAINTAIN STABILITY OF FUEL FLOW IN GAS TURBINE ENGINES
    Publication number: 20150184594
    Abstract: A system includes a gas turbine comprising a compressor section, combustor section, and a turbine section. The system further includes a first fuel line and a second fuel line coupled to the gas turbine. The system also includes a feed compressor disposed along the first fuel line upstream of the gas turbine. The feed compressor is configured to pressurize the first fuel provided to the gas turbine. Further, the system includes fuel flow maintenance system configured to provide a pressurized fuel to the first fuel line upstream of the feed compressor in response to an interruption in a flow of the first fuel along the first fuel line to the gas turbine that triggers a transition from the first fuel in the first fuel line to the second fuel in the second fuel line.

  • System and method for switching fuel feeds during gasifier start-up
    Patent number: 8845770
    Abstract: A gasification system including a gasifier, a feed injector, and a fuel feed system that includes a first feed line, a second feed line, and a controller that includes a processor. The processor is programmed to enable the first feed line to supply a fuel gas into the feed injector, enable the second feed line to supply oxygen into the feed injector, receive instructions to add a slurry to the gasifier, prevent the first feed line from supplying the fuel gas into the feed injector, enable the first feed line to supply the slurry into the feed injector, enable the second feed line to simultaneously supply the oxygen and the inert gas into the feed injector, and prevent the second feed line from supplying the inert gas into the feed injector.
