ABSTRACT:
A moisture removal scheme for an axial flow turbine apparatus is disclosed. A substantially radial groove disposed on a rotating blade conducts moisture droplets deposited on the blade in a radial direction toward a circumferential slot disposed on the interior surface of a turbine casing. The slot is radially adjacent to the radial outermost point of the groove and collects moisture thrown thereinto from the groove to eliminate that moisture from the interior of the turbine. Axial ridges are provided on the blade to guide the moisture droplets deposited thereon into the radial groove.
