Abstract
A discharge ring supporting structure of an adjustable-blade axial-flow turbine comprises upper and lower halves separated along a horizontal plane passing through the central axis of the discharge ring. The lower half of the discharge ring is supported by a plurality of supporting columns, each having upper and lower supporting members. The upper supporting members are detachably connected between the lower half of the discharge ring and the lower supporting member. When it is desired to remove the runner, the discharge ring is separated into the upper and lower halves, and the upper supporting members of the supporting columns are removed so that the discharge ring can be lowered. Lowering of the discharge ring allows the runner to be lowered and then removed axially without the runner blades contacting the discharge ring. The upper supporting members of the discharge ring supporting columns are provided with a vibration damper for damping vibration in the discharge ring.
