Abstract
A turbine is provided and includes a spacer having an annular body formed with opposing outward and inward surfaces and an orifice extending through the body from the outward to the inward surface, an assembly to secure the spacer around a rotor axially between sequential buckets of a forward turbine stage and an aft turbine stage, the spacer forming an annular passage around the rotor into which a fluid flows through the orifice and a circuit fluidly coupled to the annular passage to deliver the fluid from between the sequential buckets of the forward turbine stage and the aft turbine stage to an axial location forward of the forward turbine stage.
Claims20
A turbine, comprising:
- a spacer having an annular body formed with opposing outward and inward surfaces and an orifice extending through the body from the outward to the inward surface;
- an assembly to secure the spacer around a rotor axially between sequential buckets of a forward turbine stage and an aft turbine stage, the spacer forming an annular passage around the rotor into which a fluid flows through the orifice;
- and
- a circuit fluidly coupled to the annular passage to deliver the fluid from between the sequential buckets of the forward turbine stage and the aft turbine stage to an axial location forward of the forward turbine stage.
A turbine engine, comprising:
- a rotor disposed within a casing to define a passage through which fluid flows from a forward to an aft turbine stage at which the fluid is relatively cooled;
- a spacer having an annular body formed with opposing outward and inward surfaces and an orifice extending through the body from the outward to the inward surface;
- an assembly to secure the spacer around the rotor axially between sequential buckets of the forward and the aft stage, the spacer forming an annular passage around the rotor into which the cooled fluid flows through the orifice;
- and
- a circuit fluidly coupled to the annular passage to deliver the cooled fluid from between the sequential buckets of the forward and the aft stage to an axial location forward of the forward stage.
A steam turbine engine, comprising:
- a rotor disposed within a casing to define a passage through which steam flows from a forward to an aft turbine stage at which the steam is relatively cooled;
- a spacer having an annular body formed with opposing outward and inward surfaces and an orifice extending through the body from the outward to the inward surface;
- an assembly to secure the spacer around the rotor axially between sequential buckets of the forward and the aft stage, the spacer forming an annular passage around the rotor into which the cooled steam flows through the orifice;
- and
- a circuit fluidly coupled to the annular passage to deliver the cooled steam from between the sequential buckets of the forward and the aft stage to an axial location forward of the forward stage.
