Rotor and wheel cooling assembly for a steam turbine system

摘要

A rotor (16) and wheel (17) cooling assembly (24) for a steam turbine system (10) includes a rotor (16) operably connected to a plurality of rotating buckets. Also included is a flow diverting member (18) having an inner radius (30) and operably coupled to at least one nozzle stage (28), wherein the flow diverting member (18) directs flow in at least one direction within the steam turbine system (10). Further included is a cooling flow dispenser (26) disposed radially outwardly of a portion of the rotor (16) and having at least one aperture (42), wherein the cooling flow dispenser (26) is operably coupled to the inner radius of the flow diverting member (18).
