Abstract
A steam turbine system including a low pressure (LP) turbine has a plurality of moisture extraction points at which a steam-water mixture is extracted and passed through a respective one of a corresponding plurality of heat exchangers. Each exchanger passes the steam-water mixture in heat exchange relationship with feedwater in a feedwater conduit. A low pressure and low temperature final stage extraction point on the steam turbine is coupled to a condenser, and water collected at the condenser is directed into the feedwater conduit. The system separates at least some of the steam in the steam-water mixture from the final stage extraction point and passes this steam in heat exchange relationship with water in the feedwater conduit.
