Steam turbine system including valve for leak off line for controlling seal steam flow

摘要

A steam turbine system (100) includes a valve (102) coupled to a leak off line (104) from a leak packing (106) of a first steam turbine (110), the valve (102) controlling a first steam flow (112) used to maintain a constant self-sustaining sealing pressure to a second steam turbine (116) across numerous loading conditions. A related method is also provided.
