Abstract

A cover member defining a rotor chamber adjacent to a rotor wheel that supports a rotating blade in a turbine includes a first aperture for introducing a cooling gas stream into the rotor chamber, and a second aperture positioned in a radially outward portion of the cover member for allowing a portion of the cooling gas stream to exit the rotor chamber. The portion of the cooling gas stream exiting the rotor chamber carries dirt particles to purge the rotor chamber.
