MAIN PROPULSION STEAM TURBINES - INCREASING EFFICIENCY WITHOUT REDUCING RELIABILITY

The paper discusses in detail the design of three basic 33 MW (45,000 shp) main propulsion steam turbine units. Two of the designs are cross compound HP and LP cylinders with a choice of axially disposed or underslung condensers based upon inlet steam conditions of 62 bar (900 lb/sq in.) 513 degrees F). The third design utilizes a combined HP/LP turbine together with an LP cylinder used with a reheat cycle. Inlet steam conditions for this turbine would be 100.7 bar (1,465 lb/sq in.) 510 degrees C (950 degrees F).
