    摘要: A seal structure partitions a high-pressure portion and a low-pressure portion including spring-back seal rings on the high-pressure side, including ACC seal rings and fins on the low-pressure side. The ACC seal rings have an adjustable movable seal ring which is a movable seal ring that is movable in a substantially radial direction at a portion thereof and which partitions a high-pressure side steam chamber and a medium-pressure side steam chamber with the fins and a circumferential surface, and including a pressure equalizing pipe that connects the low-pressure side of the adjustable movable seal ring to a high-pressure outlet portion, is provided with an adjusting pipe that connects, on the high-pressure side steam chamber side of the ACC seal rings, a high-pressure dummy to the same high-pressure outlet portion as the medium-pressure side steam chamber, and an open/close valve in the adjusting pipe.

    摘要: An inner shell assembly for a steam turbine includes an inner shell with a plurality of grooves of preset dimensions, and a plurality of nozzle carriers respectively securable in the plurality of grooves. Each of the nozzle carriers supports at least one nozzle and bucket for a turbine stage via a dovetail, where the inner shell, the plurality of nozzle carriers and the nozzles and buckets define a steam path. A radial position of the dovetails in the nozzle carriers within its corresponding grooves is selectable according to the steam path, and an axial width of each of the nozzle carriers is selectable according to the steam path.

    摘要: The invention is related to a pullable drawer for removably protruding in a radial direction into an outer housing of a turbine, in order to make mechanical contact with an inner carrier being concentrically arranged within said outer housing. The pullable drawer has an essentially cylindrical body, which extends along a longitudinal drawer axis. A mechanical decoupling is provided, as the pullable drawer is divided along said longitudinal drawer axis into at least separate first and second parts. The first and second parts are coupled with each other by means of a releasable mechanical joint.
