Abstract
A fuel injector for injecting alternate fuels having a different energy density in a gas turbine is provided. A first fuel supply channel () may be fluidly coupled to a radial passage () in a plurality of vanes () that branches into passages () (e.g., axial passages) to inject a first fuel without jet in cross-flow injection. This may be effective to reduce flashback in fuels having a relatively high flame speed. A mixer () with lobes () for injection of a second fuel may be arranged at the downstream end of a fuel delivery tube (). A fuel-routing structure () may be configured to route the second fuel within a respective lobe so that fuel injection of the second fuel takes place radially outwardly relative to a central region of the mixer. This may be conducive to an improved (e.g., a relatively more uniform) mixing of air and fuel.
