  • Sealing arrangement of a steam turbine in which a sealing liquid and a vapor steam extraction system are used
    Patent number: 9885246
    Abstract: A sealing arrangement for a duct, through a stationary housing, of a shaft which rotates about an axis is provided, wherein a sealing liquid is used for sealing instead of sealing steam. The sealing arrangement includes a seal, having a vapor steam extraction system, and a feed line, which is arranged between the inner space and the vapor steam extraction system and is designed for supplying a sealing liquid, wherein a labyrinth seal, a brush seal with metallic bristles, a brush seal with bristles made of natural fibers and/or a brush seal made of synthetic fibers is provided for sealing off with respect to the inner space and the vapor steam extraction system.
