<P>PROBLEM TO BE SOLVED: To remove moisture stuck on the blade of a steam turbine by a simple structure. <P>SOLUTION: The space 31 in a blade for introducing high-temperature and high-pressure steam 30 is formed in at least one of a rotor blade 10 and a stator blade 20 in a steam turbine 1. An injection hole 32 communicating with the in-blade space 31 is formed on the backside 40 of the blade, at a position in a range from 50 to 70% of a blade width from the front edge 50 of the blade, and formed from the outer circumferential side of the blade to a range from 50 to 70% of the blade height. <P>COPYRIGHT: (C)2013,JPO&INPIT |
