摘要: A combustor nozzle includes a nozzle body that defines a cavity. An orifice in the nozzle body provides fluid communication from the cavity through the nozzle body. A movable barrier proximate to the orifice has a first position in which the movable barrier at least partially obstructs the orifice. A method for supplying fuel to a combustor includes flowing fuel through an orifice in a nozzle, determining a reactivity of the fuel, and adjusting an effective cross sectional area of the orifice based on the reactivity of the fuel.

摘要: Methods and systems are provided for delivering an additive to a turbine combustor. In one embodiment, a water injection system directs water through a water passage to a turbine combustor at a flow rate that is variable to achieve a first control function. An additive delivery system directs an amount of an additive through the water passage to the combustor to achieve a second control function. The amount of the additive is variable based on the flow rate of the water, and the first and second control functions are different from one another.

摘要: An optimized combustor cooperating with a compressor in driving a gas turbine comprises a cylindrical outer combustor wall having an upstream fuel entry region and a downstream turbine entry region. An array of mixing holes are disposed about the periphery of the outer combustor wall adjacent to the fuel entry region so as to lower Nox production therein. An array of dilution holes are medially disposed within the outer combustor wall to provide an entry for dilution air to the combustor.
