ABSTRACT:
A steam turbine has an outer blade ring supporting a row of stationary blades and an adjacent downstream row of long rotatable blades. The outer blade ring has a generally conical flow-guiding surface for outwardly guiding the steam as it flows through the row of stationary blades. The outer blade ring is supported by a radially juxtaposed carrier ring having a flow-guiding surface axially adjacent to and extending outwardly from the flow-guiding surface of the outer blade ring. A spacer ring is axially adjacent to the carrier ring and has a flow-guiding surface adjacent to and extending outwardly from the flow-guiding surface of the carrier ring. An exhaust flowguide is axially adjacent the spacer ring and radially adjacent the row of rotatable blades for guiding the steam from the rotatable blades.
