  • Method and apparatus for eliminating thermal bowing and axial thrust loads of steam turbine rotors
    Patent number: 6517314
    Abstract: In a steam turbine, a combined brush and labyrinth seal is provided between a diaphragm web and axial projecting platforms on bucket dovetails at a location spaced radially outwardly of the outer diameter of the rotor. The downstream axially adjacent bucket dovetails also have platforms serving as complementary sealing surfaces to labyrinth teeth formed on the web. By locating the combined labyrinth and brush seal radially outwardly of the outer diameter of the shaft, thermal bowing of the rotor is eliminated. By providing backup labyrinth seals at the same radial location, axial thrust loads are eliminated in the event of brush seal failure.
