A combustor and a method for cooling the combustor

摘要

A combustor 10 includes a first shroud 50 extending circumferentially inside the combustor 10 and at least partially defining an inlet passage 52. A second shroud 110 extends circumferentially inside the combustor 10. The second shroud 110 defines an outlet passage 112. A first plate 70 extends radially inside the second shroud 110 downstream from the inlet passage 52 of the first shroud 50 and upstream from the outlet passage 112 of the second shroud 110. The first plate 70 generally defines an inlet port 82 and an outlet port 84. A second plate 96 extends radially around the first plate 70 downstream from the inlet port and upstream from the outlet port of the first plate. A first fluid flow path 116 extends from the inlet passage to the inlet port. A second fluid flow path 118 extends from the outlet port to the outlet passage. A baffle 62 extends from the first shroud 50 to the first plate 70. The baffle 62 separates the first and second fluid flow paths.
