COOLING JACKET OF COMBUSTOR, COMBUSTOR EQUIPPED WITH THE SAME, AND GAS TURBINE EQUIPPED WITH THE COMBUSTOR

摘要

PROBLEM TO BE SOLVED: To provide a cooling jacket of a combustor which maintains the soundness of the cooling jacket against a generated thermal stress, and to provide the combustor equipped with the same and a gas turbine equipped with the combustor. SOLUTION: The cooling jacket of the combustor includes a cylindrical wall 2 into which combustion gas flows, an outer cylinder 4 provided annularly around the outer periphery of the wall 2 and forming a refrigerant passage 17 for passage of a refrigerant between the same and the wall 2, and a plurality of ribs 16 connecting the outer cylinder 4 to the wall 2. The plurality of ribs 16 have legs each widening toward the wall 2 and the legs are connected to the wall 2 by welding. COPYRIGHT: (C)2011,JPO&INPIT
