Sealing system for rotors |
摘要 |
Turbine blade shrouds are sealed by injecting air on to the shroud immediately upstream of a shroud seal. This air serves two purposes: it creates a turbulent flow immediately upstream of the shroud seal, thus spoiling and reducing the leakage flow over the seal, and the hot gases which would otherwise leak over the seal are replaced by the cooler air, thus reducing energy wastage and improving S.F.C. (specific fuel consumption).
