FUEL NOZZLES

In accordance with at least one aspect of this disclosure, a nozzle for a fuel injector includes, a nozzle body (110) defining a central axis from a nozzle inlet (112) to a nozzle outlet (114). A first fuel circuit (122) is defined in the nozzle body (110) configured to issue a first fuel flow from a first outlet orifice (126) into a combustor. A second fuel circuit (128) is defined in the nozzle body (110) radially outward from the first fuel circuit (122) configured to issue a second fuel flow from a second outlet orifice (132) at a prefilmer surface of the nozzle body (110). A third fuel circuit (136) is defined in the nozzle body (110) radially outward from the second fuel circuit (128) configured to issue a third fuel flow from a third outlet orifice (140) at the prefilmer surface of the nozzle body (110). In embodiments, the first fuel circuit (122), the second fuel circuit (128), and the third fuel circuit (136) can all be fluidly isolated from one another within the nozzle body (110).
