| description | A rotating gas turbine blade comprises an airfoil (14) with a suction side and a pressure side (12), said airfoil (14) extending in a radial direction from a blade root to a blade tip, wherein said blade tip (15) comprises a tip shroud (16), said airfoil (14) comprises internal cooling passages (27, 28) for a cooling medium, which extend through said tip shroud (16), and outlet ports (25) are provided above a selected internal airfoil cooling passage (27) for said cooling medium to be ejected above said tip shroud (16) in direction of the blade's pressure side (12). The blades' lifetime is improved by providing means (26) for avoiding dust accumulation at the tip end of said selected internal cooling passage (27). A corresponding gas turbine is also provided.
旋转燃气涡轮叶片包括具有吸力侧和压力侧(12)的翼型件(14)，所述翼型件(14)沿径向方向从叶片根部延伸到叶片末梢，其中所述叶片末梢(15)包括末梢护罩(16)，所述翼型件(14)包括用于冷却介质的内部冷却通路(27、28)，其延伸通过所述末梢护罩(16)，并且出口端口(25)设置在选定的内部翼型件冷却通路(27)上方，以便在所述末梢护罩(16)上方沿叶片的压力侧(12)的方向喷射所述冷却介质。通过提供避免所述选定的内部冷却通路(27)的末梢端处的积尘的器件(26)来改进叶片的寿命。 |
