摘要： PROBLEM TO BE SOLVED: To overcome the problem that the moisture content adhered to the moving blade has so far been removed by providing the moving blade of a steam turbine with grooves extending in a blade length direction and aligning their upper ends and the end surface of the moving blade cover or making holes through the moving blade cover, whereas an increased number of grooves increases the area through which the inside and outside of the moving blade cover communicate with each other, resulting in an increase in the loss of steam. SOLUTION: A drain guide groove 4 is provided on the moving blade-side side surface of a tip cover 3 which is provided at the leading end of the moving blade 1. The moving blade 1 is provided with a moisture content trapping grooves 2 extending in a blade length direction. The drain guide groove 4 is positioned above the moisture content trapping grooves 2.

The moisture content adhered to the moving blade 1 is discharged by way of the moisture content trapping groves 2 and the drain guide groove 4 from the water droplet ejection outlet 5 to a drain pocket 7. Thereby, only one water droplet ejection outlet enables removal of the moisture content adhering to the moving blade 1. COPYRIGHT: (C)2011,JPO&INPIT
