Abstract
An igniter and fuel atomizer nozzle assembly in a gas turbine engine includes an igniter in which a fuel conduit is positioned in a passageway in the igniter between its housing and its electrode for discharging atomized start up fuel from the end of the igniter housing closely proximate to the ignition spark generated by the electrode.
Claims25
A combination igniter and fuel atomizer nozzle assembly for a gas turbine, comprising:
- an igniter, said igniter including an elongate conductive electrode and an elongate conductive housing surrounding said electrode and defining an elongate air passageway in said housing between said electrode and said housing, an end of said electrode and said housing being positioned proximate to each other to define a gap through which a spark will jump between the ends of said housing and electrode when electrical energy is imparted to one of said electrode and housing, and means for communicating air to said air passageway during operation of the turbine, and
- a liquid fuel atomizer nozzle, said atomizer nozzle including a fuel discharge orifice proximate the ends of said electrode and said housing and adjacent said gap for discharging finely atomized liquid fuel adjacent said gap, and a fuel conduit in said air passageway and communicating with said fuel discharge orifice to communicate fuel to said orifice for atomization and discharge therefrom.
A combination igniter and fuel atomizer nozzle assembly, comprising:
- an igniter, said igniter including at elongate conductive electrode and an elongate conductive housing surrounding said electrode, an end of said electrode and said housing being positioned proximate to each other to define a gap through which a spark will jump between the ends of said housing and electrode when electrical energy is imparted to one of said electrode and housing;
- and
- a fuel atomizer nozzle, said atomizer nozzle including a fuel discharge orifice proximate the ends of said electrode and said housing and adjacent said gap for discharging finely atomized fuel adjacent said gap, and wherein the atomized fuel is discharged from said orifice of said fuel atomizer nozzle at a location spaced radially from and eccentrically to the end of said elongate conductive electrode.
