BLADE AND GAS TURBINE
Document Type and Number:
Japanese Patent JP2018141393
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve the cooling performance by efficiently cooling a shroud in a blade and gas turbine.SOLUTION: A blade comprises: a hollow shaped stationary blade body 22; an inner shroud 23 connected to one end part in a longer direction of the stationary blade body 22; an outer shroud 24 connected to the other end part in the longer direction of the stationary blade body 22; and a chiller for supplying cooling air to the inner shroud 23 through the inside the stationary blade body 22 from the outer shroud 24. As the chiller, turbulators 66, 75, 94, and 104 are provided in side end side cooling passages 64, 73, 93, and 103 in each of the shrouds 23 and 24 so that the arrangement density of the closest position to the stationary blade body 22 becomes high.SELECTED DRAWING: Figure 2
