A multiphase fuel injector has an injector body with a fuel inlet at a first end and a fuel outlet at a second end opposite the first end. A primary circuit disposed proximate the fuel inlet extends into a central portion of the injector body. The primary circuit is configured to receive a first flow of pressurized fuel from the fuel inlet that discharges into a spin chamber in the injector body downstream from the fuel inlet. The primary circuit is configured to impart a swirling action to the first flow of pressurized fuel. A secondary circuit is located in the injector body radially outward from the primary circuit. The secondary circuit is configured to receive a second flow of pressurized fuel from the fuel inlet that discharges into the fuel outlet. The secondary circuit is configured to impart a swirling action to the second flow of pressurized fuel.

Multiphase fuel injector

The subject matter of this specification can be embodied in, among other things, a method that includes igniting an igniter stage configured to ignite combustion in a turbine combustor assembly, receiving pressure signals from a pressure sensor configured to sense pressure in the turbine combustor assembly, and controlling operation of the igniter stage based on the received pressure signals.

Ignition system for power generation engine

The subject matter of this specification can be embodied in, among other things, a turbine combustor assembly includes a primary combustion chamber in fluid communication with a primary fuel injector and a primary air inlet, and an igniter carried by the primary combustion chamber and including a first igniter stage having an auxiliary combustion chamber housing comprising a mixing chamber and a tubular throat converging downstream of the mixing chamber, an ignition source projecting into the mixing chamber of the auxiliary combustion chamber, and a second igniter stage that includes an auxiliary fuel outlet manifold proximal to an outlet of the tubular throat.
