STEAM TURBINE NOZZLE VANE ARRANGEMENT AND METHOD OF MANUFACTURING

摘要

A steam turbine nozzle vane arrangement includes a first nozzle vane comprising a first radially outer end and a first radially inner end, the first nozzle vane located in a steam turbine housing and operatively coupled to the steam turbine housing proximate the first radially outer end. Also included is a second nozzle vane operatively coupled to the steam turbine housing proximate a second radially outer end, the second nozzle vane located adjacent the first nozzle vane in a circumferentially aligned turbine stage. Further included is a first cover located proximate the first radially inner end and having a first hole. Yet further included is a second cover located proximate a second radially inner end of the second nozzle vane and having a second hole. Also included is a pin disposed within the first and second hole, the pin configured to fixedly couple the first and second nozzle vanes.
