摘要： In a conventional secondary fuel nozzle for a gas turbine combustion system, secondary air enters and flows around pegs to mix with fuel injected through holes in pegs. Because the pegs are in the air flow area, undesirable pressure drops occur adversely affecting turbine's efficiency and leading to higher emissions. A novel secondary fuel nozzle is provided in which fuel is injected upstream of the secondary air entry location, which allows the pegs to be removed from the flow area. An example secondary fuel nozzle includes a nozzle body delivering fuel, a nozzle housing surrounding the nozzle body and defining air passages for the secondary air to enter and flow toward an end of the nozzle body, and a premix fuel unit positioned upstream of the air passages injecting fuel delivered by the nozzle body into the secondary air for premixing prior to combustion.

摘要： A nozzle includes an inlet, an outlet, and an axial centerline. A shroud surrounding the axial centerline extends from the inlet to the outlet and defines a circumference. The circumference proximate the inlet is greater than the circumference at a first point downstream of the inlet, and the circumference at the first point downstream of the inlet is less than the circumference at a second point downstream of the first point. A method for supplying a fuel through a nozzle directs a first airflow along a first path and a second airflow along a second path separate from the first path. The method further includes injecting the fuel into at least one of the first path or the second path and accelerating at least one of the first airflow or the second airflow.

摘要： A premixer is provided for injecting premixed fuel-air mixture into the inlet of a combustion apparatus. In one embodiment, the premixer assembly comprises a plurality of concentric, aerodynamic injector rings, with radially-directed injection holes. The injection holes have a plurality of different diameters, facilitating good mixing over a broad power range. Due to configuration and hole sizes, the assembly is gas or liquid compatible. The radial, concentric injection formation allows for a short injection path.
