A burner nozzle assembly comprising a nozzle body having a body inlet end, a body outlet end spaced apart from the body inlet end, a body air inlet adapted to convey a quantity of air, and a body fuel inlet adapted to convey a quantity of fuel, a nozzle mixer having a mixer inlet end, a mixer outlet end spaced apart from the mixer inlet end, a mixer air inlet adapted to convey the quantity of air, a mixer fuel inlet adapted to convey the quantity of fuel, and a mixing zone, a nozzle cap which is disposed adjacent to the body outlet end and the nozzle mixer, and a pintle which is partially disposed in the nozzle mixer. The mixer air inlet forms a substantially conical shape. A method for producing a burner flame.

A nozzle for a combustor is disclosed. The nozzle may include a main fuel passage (202), a number of radial fuel ports (206) in communication with the main fuel passage, a prefilmer surface (212) in communication with the radial fuel ports, and a main purge air passage (218) in communication with the radial fuel ports and the prefilmer surface.

Described herein is an atomizer nozzle for atomizing a first fluid by means of a second fluid, including a nozzle body and a nozzle head. The nozzle head is designed as a sleeve-shaped cap attached to a part of the outer surface of the nozzle body, and the outer flow channel includes two sections, a first section extending completely in the nozzle body, and a second section being formed by the outer surface of the nozzle body and the inner surface of the nozzle head.

A pilot fuel injector is provided for a fuel nozzle of a gas turbine engine. The pilot fuel injector can include an axially-elongated, inner pilot centerbody wall extending from an upstream end to a downstream end, with the axially-elongated, inner pilot centerbody wall having a diverging-converging orientation with respect to a centerline axis to define a hollow tube having an upstream diameter, a throat, and a downstream diameter such that the throat has an inner diameter that is less than both of the upstream diameter and the downstream diameter. The pilot fuel injector also includes a center air circuit positioned at the upstream end, and an annular fuel passage defining the downstream end and intersecting with the centerbody wall at a pilot fuel metering orifice. A pilot fuel film surface is downstream from the annular fuel passage.
