Abstract

This invention concerns the use of pressurized steam as the cooling medium in the combustor wall of a gas turbine combustor. It is distinguished by the following. The combustor wall is configured by 1) a plurality of cooling channels for cooling steam, sealed by an exterior wall panel and a heat-resistant plate which are assembled by soldering or some other method; 2) a supply manifold for supplying the cooling steam into the cooling channels, which is provided on one end of the cooling channels; and 3) a recovery manifold for recovering the cooling steam from the cooling channels, which is provided on another end of the cooling channels. This arrangement can form strong enough steam-channels that do not allow any leakage of the high pressure steam from the cooling system.
