PLATE FIN STRUCTURE FOR GAS TURBINE COMBUSTOR, AND GAS TURBINE COMBUSTOR

摘要

PROBLEM TO BE SOLVED: To provide a plate fin structure for a gas turbine combustor that can be effectively cooled with a small cooling air quantity via an improved cooling performance of a wall surface cooling structure. SOLUTION: The plate fin structure for a gas turbine combustor is so designed that a shell 13 encloses from outside a fin ring 11 with many fins 12A on a rear surface, and a cooling air flow CA1 led between the fin ring 11 and the shell 13 flows between the fins 12A to offer convective cooling. The fins 12A are arranged slantingly at an angleθto a combustor axis.
