Abstract:
An arrangement for radially positioning a turbine brush seal relative to turbine rotor, comprising:a main seal segment having a slot open toward a turbine rotor and defining an interior ledge facing away from the rotor;a brush seal segment having an exterior shoulder facing toward the rotor and a portion smaller in size cross-sectionally than said slot of said main seal segment so as to allow insertion of said brush seal segment into said slot such that said exterior shoulder of said brush seal segment overlies said interior ledge of said main seal segment and said brush seal segment can move radially relative to said main seal segment and the rotor and said exterior shoulder of said brush seal segment can move toward and away from said interior ledge of said main seal segment;means for establishing a minimum spacing between said interior ledge of said main seal segment and said exterior shoulder of said brush seal segment; andmeans for forcing said brush seal segment toward the rotor such that said exterior shoulder of said brush seal segment is brought toward said interior ledge of said main seal segment so as to place and hold said exterior shoulder of said brush seal segment at said minimum spacing from said interior ledge of said main seal segment and thereby prevent radial floating of said brush seal segment relative to said main seal segment and to the rotor.
