ABSTRACT:
A dual fuel mixer is disclosed having a mixing duct, a shroud surrounding the upstream end of the mixing duct having contained therein a gas fuel manifold and a liquid fuel manifold in flow communication with a gas fuel supply and a liquid fuel supply, respectively, and control means, a set of inner and outer annular counter-rotating swirlers adjacent the upstream end of the mixing duct, where at least the outer annular swirlers include hollow vanes with internal cavities and gas fuel passages, all of which are in fluid communication with the gas fuel manifold to inject gas fuel into the air stream, the vane cavities also having liquid fuel passages therethrough in fluid communication with the liquid fuel manifold, and a hub separating the inner and outer annular swirlers to allow independent rotation thereof, the hub having a circumferential slot in fluid communication with the liquid fuel passages which injects liquid fuel into the air stream, wherein high pressure air from a compressor is injected into the mixing duct through the swirlers to form an intense shear region and gas fuel is injected into the air stream from the outer annular swirler vanes and/or liquid fuel is injected into the air stream from the hub slot.
