Title:
蒸気グランド用のハイブリッド型ハニカム・ブラシシール
Document Type and Number:
Japanese Patent JP4490670
Kind Code:
B2
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.
