Abstract

PURPOSE: To uniformly introduce a cooling liquid into a cooling passage to uniformly cool a turbine bucket, by providing a capillary material for the measuring weir of the cooling passage in the turbine bucket.
CONSTITUTION: A cooling liquid is introduced into a passage 4 at a mount 3 through the inlet port 2 of a turbine disc 1 to cool the mount 3. A capillary material 9 such as a wick or a porous material is provided at the front end of a measuring weir 5. After the cooling liquid having overflowed the surface 8 of the measuring weir 5 is caused to uniformly flow around in the circumferential direction by the capillary force of the capillary material 9, the cooling fluid is introduced into a cooling passage 7. The cooling liquid can thus be uniformly introduced into each cooling passage in a turbine bucket to uniformly cool the bucket even if the surface of the measuring weir 5 is not so formed that the distance of each part of the surface from the axis of a rotary turbine shaft is not accurately equal.
