    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.
