System and method for controlling leakage steam to the steam seal header to improve the steam turbine performance

摘要

PROBLEM TO BE SOLVED: To provide a system and method for controlling leak steam to steam seal header for improving system turbine performance.;SOLUTION: A turbine system (100) is provided wherein during self-sealing operating conditions, excess leakoff steam is restricted from being dumped to a steam seal header (130) and is diverted into the working steam flow path, hence increasing net output and efficiency for the turbine system (100). A related method is also provided.;COPYRIGHT: (C)2012,JPO&INPIT
