Claim 17:
18. A method, comprising:
directing a leaked fuel from a first fuel conduit through a first fuel sweep opening of a fuel sweep system into a passage between a liner and a flow sleeve of a combustor, wherein the liner is disposed about a combustion chamber, the flow sleeve is disposed about the liner, the passage is in fluid communication with the combustion chamber, a compressor discharge chamber is disposed about the flow sleeve, the first fuel conduit is disposed in the compressor discharge chamber along the flow sleeve, the first fuel conduit is offset from an exterior surface of the flow sleeve in a radial direction relative to a longitudinal axis of the combustor, the first fuel sweep opening is disposed in the flow sleeve, and the first fuel conduit is centered over the first fuel sweep opening; and
directing the leaked fuel from the first fuel sweep opening in a flow direction along the passage via a first fuel sweep louver of the fuel sweep system, wherein the first fuel sweep louver is coupled to the flow sleeve adjacent the first fuel sweep opening, the first fuel sweep opening and the first fuel sweep louver are disposed radially inward relative to the first fuel conduit, and the first fuel sweep opening and the first fuel sweep louver overlap the first fuel conduit in a circumferential direction and an axial direction relative to the longitudinal axis of the combustor.
