摘要： The application may further describe a seal guard in a turbine where the turbine include a plurality of circumferentially spaced nozzles, a plurality of circumferentially spaced turbine blades that each include a blade cover, and an opening defined by a trailing edge of the nozzles and a leading edge of the blade covers. The seal guard may include an upstream axial fin positioned at the trailing edge of the nozzles that extends in a downstream direction across at least part of the opening or a downstream axial fin positioned at a leading edge of a blade cover that extends in an upstream direction across at least part of the opening.

摘要： Disclosed herein is a rotor assembly for a steam turbine including a stacked rotor section having rotor plates. The rotor plates include a main body portion having a plate shape and a first axial face and a second axial face opposite to the first axial face. The rotor plates also include an airfoil base surface at an outer radial edge of the main body portion. The rotor plates further include buckets which extend radially outward from the airfoil base surface. And the rotor plates yet further include a seal disposed to prevent steam exposure to the first and second axial faces.

摘要： The steampath for a steam turbine includes stacked stator rings each mounting inwardly directed nozzles and stacked rotor wheels each mounting outwardly directed buckets mounting blades. By alternately stacking the stator rings and rotor wheels, the nozzles and buckets of the various stages are interdigitated to form a steampath. Each bucket includes a blade and a root received in a generally complementary shaped groove on a wheel.
