Removable abradable seal carriers for sealing between rotary and stationary turbine components

Removable abradable seal carriers for sealing between rotary and stationary turbine components

The turbine includes a diaphragm having a seal carrier mounted in opposition to seal teeth carried by the rotary component. The seal carrier includes a seal face having a coating of abradable materialenabling the rotary component to abrade the material from the seal face. The seal carrier is removab...

description The turbine includes a diaphragm having a seal carrier mounted in opposition to seal teeth carried by the rotary component. The seal carrier includes a seal face having a coating of abradable materialenabling the rotary component to abrade the material from the seal face. The seal carrier is removable from the diaphragm and is carried by an axial extension integral with or removable from the outer diaphragm ring. A spring may be interposed between the seal carrier and the stationary component.
