The invention relates to a gas turbine (1) which comprises a compressor (2), one or more combustors (3) and a turbine (4). A transition piece (5) is provided between the one or more combustors (3) and the turbine (4) for guiding a hot gas (45) generated in the one or more combustors (3) to the turbine (4). The transition piece (5) has an inner shell (8) and an outer shell (9) defining an annular chamber (13). The inner shell (8) has a wall (18) with cooling holes (20, 23, 28). The first cooling holes (20) closer to the turbine (4) have a larger angle (21) than second cooling holes (23) farther from the turbine (4), each angle (21) being defined by a longitudinal axis (25) of the cooling hole directed towards the annular chamber (13) and an axis (27) perpendicular to the wall (18). 本发明涉及燃气涡轮。具体地，燃气涡轮（1）包括压缩机（2）、一个或多个燃烧器（3），以及涡轮（4）。在一个或多个燃烧器（3）与涡轮（4）之间提供过渡件（5）用于将在一个或多个燃烧器（3）中所生成的热气体（45）引导至涡轮（4）。过渡件（5）具有限定环形室（13）的内壳（8）和外壳（9）。内壳（8）具有带有冷却孔（20、23、28）的壁（18）。更靠近涡轮（4）的第一冷却孔（20）相比于距涡轮（4）更远的第二冷却孔（23）具有更大的角度（21），每个角度（21）
