GAS TURBINE COMBUSTOR

摘要

A combustor inner cylinder is disposed inside a combustor outer casing, and a spread flame formation cone and a plurality of premixed flame-formation nozzles are provided inside the combustor inner cylinder. The premixed flame-formation nozzles have sector-shaped outlets and disposed annularly between the combustor inner cylinder and the spread flame formation cone which forms spread combustion flames. Part of the air from a compressor is passed through clearances between the premixed flame-formation nozzles as cooled air and discharged toward a combustion chamber.
