ABSTRACT:
A steam turbine includes, in one exemplary embodiment, a rotor and a plurality of bucket stages coupled to the rotor with each bucket stage including a plurality of circumferentially spaced buckets coupled to the rotor. The steam turbine also includes a diaphragm assembly surrounding the rotor and the bucket stages, and an outer casing disposed about the rotor and diaphragm assembly. The diaphragm assembly includes a plurality of nozzle stages located between the bucket stages, a circumferentially extending groove, with the groove located upstream of one of the bucket stages and between that bucket stage and an adjacent nozzle stage, a circumferentially extending extraction chamber, and at least one first bore extending from the groove to the extraction chamber. The diaphragm assembly also includes at least one second bore extending from the extraction chamber through an outer surface of the diaphragm assembly.
