  • Brush seals for steam turbine applications
    Patent number: 6250640
    Abstract: A number of sealing segments 20 mounts a brush seal about a rotor. The tips of the brush seal 46 are maintained out of contact with the rotor surface throughout the entire operating range of the turbomachinery. Thus, the increase in temperature resultant from rubs between the bristle tips and the rotor 12 which effectively increase vibrations of the turbomachinery are eliminated. Brush seals are therefore maintained out of contact with the rotor throughout the entire operating range of the turbomachinery and thus do not affect the dynamic behavior of the rotor.
