ABSTRACT:
Film cooling of the blades of an expander is achieved by supplying steam generated at the outlet of the expander to a plurality of discharge points. In one embodiment, a plurality of passages are formed in the hub of the expander and underlie each of the vanes. Tubes are located at the inlet end of each vane and form a fluid path with the associated underlying passage and discharge steam over the entire height of the inlet end of the vane. Additional passages provide fluid communication between the underlying passages and the base of the associated vane so that film cooling is supplied to the entire inducer section of the expander.
