GAS TURBINE AND METHOD OF FORMING INSERTION HOLE FOR COMBUSTOR OF GAS TURBINE

摘要

A gas turbine (1) comprises a combustor (39), a tubular-shaped combustion section casing (31) for housing the combustor (39), and a combustor insertion hole (31a) formed in the side circumferential portion of the combustion section casing (31). The size of the insertion hole (31a) in the direction diagonal to the circumferential direction of the combustion section casing (31) is made to be larger than the size of the combustion section casing (31) in the circumferential direction, and furthermore, when the combustor (39) inserted into the hole, a member moved together with the combustor (39) and the hole are viewed from the moving direction of the combustor (39), the hole involves the entire of the external form of the combustor (39) and the member moving together with the combustor (39).
