Abstract
A fuel injector for injecting fuels having a different energy density in a gas turbine is provided. A first fuel supply channel () and a second fuel supply channel () may be coaxially arranged in a fuel delivery structure (). A first set of vanesincludes a radial passage () in fluid communication with the first channel () to receive a first fuel. Passage () branches into passages () each having an aperture () to inject the first fuel without jet in cross-flow injection. A second set of vanes () includes a radial passage () in fluid communication with the second channel () to receive a second fuel. Passage () branches into passages () each having an aperture () 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.
