  • Hybrid honeycomb and brush seal for steam gland
    Patent number: 6827350
    Abstract: A steam gland includes a steam inlet scroll and an extraction scroll axially spaced from one another defining high and low pressure regions. A seal body is disposed between the regions and includes a pair of brush seals axially spaced from one another. Intermediate the brush seals is a honeycomb seal. The hybrid brush seal/honeycomb seal combination minimizes steam leakage between the high and low pressure regions and eliminates the possibility of heat induced damage to the rotor while optimizing seal leakage performance.
