Abstract
In a gas turbine combustor and a gas turbine, an air passage () that supplies combustion high-pressure air, a pilot nozzle (), a main fuel nozzle (), and a top hat nozzle () that supply fuel, and openings () that supply film air (cooling air) are provided with respect to a combustor inner cylinder (), and contraction members (, and) are arranged along a circumferential direction on an inner wall surface in a downstream of a flow direction of combustion gas in the inner cylinder (). The contraction members (, and) are provided in a predetermined area in the circumferential direction excluding penetrating portions (, and), which do not disturb the flow of cooling air, thereby enabling to suppress generation of carbon monoxide and the like and to suppress the occurrence of unstable combustion.
