ABSTRACT:
The inlet flow guide includes a generally cylindrical shroud plate, a generally cylindrical bridge piece, elongated attachment members, biasing members and sealing members. The shroud plate is in confronting cylindrical sections, is adapted to be attached to the pair of confronting stationary blades of the annular rows of turbine blades, and includes tapped bores therethrough. The cylindrical sections of the shroud plate are in arc cylindrical sections. The bridge piece is in semi cylindrical sections and has bores therethrough of a predetermined size to accommodate expected movements during the operation of the turbine, and which are capable of alignment with the bores of the shroud plate. The attachment members have enlarged heads and shoulders and are disposed within the bores of the bridge piece and shroud plate to attach the bridge piece to the shroud plate. The biasing members are disposed between the heads of the attachment members and the bridge piece to apply a predetermined load to the bridge piece as the attachment members are tightened. The sealing members are disposed between each of the biasing member and the bridge piece to block the flow of low pressure steam through the bores in the bridge piece and to provide a seat for the biasing members.
