Title:
MOISTURE SEPARATING DEVICE FOR STEAM TURBINE
Document Type and Number:
Japanese Patent JPS63117104
Kind Code:
A
Abstract:
PURPOSE:To aim at improvement in the drain trapping rate of the device in the caption by forming a groove, which has greater width than that of a suction slit, at the surface side end portion of the suction slit provided on the surface of a stationary blade. CONSTITUTION:On the surface of a stationary blade 2, a section slit 6 is provided to be intercommunicated with the low-pressure side of a condenser and the like through a cavity 7. At the surface side end portion of the suction slit 6, there is formed a through-groove 5, which has greater width than that of the suction slit 6 and runs in the same direction as the suction slit 6 does. Drain in a steam passage is trapped into the groove with greater width, thereby the drain trapping rate being enhanced.
