Abstract
PURPOSE: To uniformly cool a moving blade of a turbine having coolant flow lines under surfaces of the blade, by connecting radially provided main flow lines and many cooling flow lines of chord direction and communicating the cooling flow lines of chord direction with sub-flow lines.
CONSTITUTION: Plural cooling flow lines 7 extending to the direction of a chord are arranged in a core 2 of a turbine moving blade 1, and both end parts of said cooling flow line 7 are connected to a radially extended main flow line 8 in the leading edge part and 9 in the trailing edge part. The neighboring cooling flow lines 7 are connected by sub-flow lines 10. A coolant meanders to flow in the cooling flow lines 7 and the sub-flow lines 10 and cools the blade. Generated steam in the cooling flow lines 7 is mainly circulated in the main flow lines 8, 9 and emitted from a blow-off hole 13. In this way, circulation of the coolant is not disturbed by the steam generated in the blade, thus the moving blade can be uniformly and effectively cooled.
