1. A system, comprising:
a combustor, comprising:
a combustion chamber;
a liner disposed about the combustion chamber;
a flow sleeve disposed about the liner; and
a passage disposed between the liner and the flow sleeve, wherein the passage is in fluid communication with the combustion chamber;

a compressor discharge chamber disposed about the flow sleeve;
a first fuel conduit disposed in the compressor discharge chamber along the flow sleeve, wherein 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, and the first fuel conduit is configured to couple to and extend between a fuel supply and a first fuel nozzle; and
a fuel sweep system configured to sweep a leaked fuel from the first fuel conduit into the passage, wherein the fuel sweep system comprises a first fuel sweep opening in the flow sleeve and a first fuel sweep louver 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 conduit overlaps with the first fuel sweep opening and the first fuel sweep louver along the flow sleeve in an axial direction and a circumferential direction relative to the longitudinal axis of the combustor;
