<P>PROBLEM TO BE SOLVED: To provide a combustor providing compatibility between combustion stability during low load and reduction of carbon smoke during high load. <P>SOLUTION: The combustor 3 includes: a housing fixing a position of an end of a longitudinal direction one side of a liner 12 with respect to a provided position of a fuel supply nozzle 11, and allowing free thermal elongation of the liner 12 in the longitudinal direction other side; and a sleeve 20 fixed to the liner 12 in the longitudinal direction other side, fitting together with the fuel supply nozzle 11 so as to freely slide in the longitudinal direction, and formed with a first passage 23 with one end 21 opened to an exterior and the other end 22 opened to an inner circumferential surface 20a fitting together with the fuel supply nozzle 11. A configuration of forming a second passage 33 with one end 31 opened to an outer circumferential surface 11a fitting together with the sleeve 20 and the other end 32 opened to a combustion region 13 is adopted in the fuel supply nozzle 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
