Abstract
A combustor that causes compressed air supplied from a compressor to combust together with fuel. The combustor includes at least one fuel nozzle having a fuel flow path for supplying fuel and a purge air flow path for ejecting purge air. The combustor further includes a nozzle-securing part for securing at least one fuel nozzle; and a top hat body located on the outer peripheral side of at least part of the nozzle-securing part. The top hat body has a first internal flow path capable of supplying compressed air to the nozzle-securing part from a space on the outer peripheral side of the top hat body. The nozzle-securing part has a second internal flow path capable of supplying compressed air supplied from the first internal flow path to the purge air flow path of the fuel nozzle.
