摘要： A combustor assembly is disclosed. The combustor assembly may include an annular trapped vortex cavity located adjacent to a downstream end of a bundle of air/fuel premixing injection tubes. The annular trapped vortex cavity may include an opening at a radially inner portion of the annular trapped vortex cavity adjacent to the head end of the bundle of premixing tubes. The annular trapped vortex cavity may also include one or more air injection holes and one or more fuel sources disposed about the annular trapped vortex cavity such that the one or more air injection holes and the one or more fuel sources are configured to drive a vortex within the annular trapped vortex cavity.

摘要： In one embodiment, a system includes a fuel injector including a liquid fuel passage extending to a first port in a tip portion. The fuel injector also includes a selectable flow passage extending to a second port in the tip portion. The selectable flow passage surrounds the liquid fuel passage to the tip portion, the selectable flow passage is configured to selectively receive a gas fuel flow and an air flow, and the selectable flow passage has a flow temperature configured to cool a liquid fuel flowing through the liquid fuel passage to reduce coking.

摘要： The present application and the resultant patent provide a fuel nozzle for mixing a flow of air and a flow of fuel within a combustor. The fuel nozzle may have one or more air passages for the flow of air, one or more fuel pegs for the flow of fuel, and a liner in communication with the air passages and surrounding the fuel pegs. The liner may include a number of ribs thereon so as to promote mixing of the flow of air and the flow of fuel therein.
