Gas turbine and method for reducing bucket tip shroud creep rate

A bucket tip shroud (10) in a gas turbine includes a seal rail (12) having a cutter tooth (14) at one end. Bucket tip shroud creep rate can be reduced by removing the cutter tooth from the bucket tip shroud seal rail after use or with a pre-groove honeycomb shroud. Preferably, the remaining geometry...

Zusammenfassung:A bucket tip shroud (10) in a gas turbine includes a seal rail (12) having a cutter tooth (14) at one end. Bucket tip shroud creep rate can be reduced by removing the cutter tooth from the bucket tip shroud seal rail after use or with a pre-groove honeycomb shroud. Preferably, the remaining geometry matches a geometry of the seal rail within a predetermined tolerance.
