A turbine (10) is provided and includes a spacer (80) having an annular body (81) formed with opposing outward and inward surfaces (82, 83) and an orifice (90) extending through the body from the outward to the inward surface, an assembly (100) to secure the spacer (80) around a rotor (30) axially between sequential buckets (110, 111) of a forward turbine stage and an aft turbine stage, the spacer (80) forming an annular passage (120) around the rotor into which a fluid flows through the orifice and a circuit (130) fluidly coupled to the annular passage (120) to deliver the fluid from between the sequential buckets (110, 111) of the forward turbine stage and the aft turbine stage to an axial location forward of the forward turbine stage. |
