Title: Fuel injector including tandem vanes for injecting alternate fuels in a gas turbine

Abstract

A fuel injector for injecting fuels having a different energy density in a gas turbine is provided. A first fuel supply channel (18) and a second fuel supply channel (20) may be coaxially arranged in a fuel delivery structure (12). A first set of vanes 22 includes a radial passage (24) in fluid communication with the first channel (18) to receive a first fuel. Passage (24) branches into passages (26) each having an aperture (28) to inject the first fuel without jet in cross-flow injection. A second set of vanes (32) includes a radial passage (34) in fluid communication with the second channel (20) to receive a second fuel. Passage (34) branches into passages (36) each having an aperture (38) arranged to inject the second fuel also without jet in cross-flow injection. This arrangement may be effective to reduce flashback that otherwise may be encountered in fuels having a relatively high flame speed.
