More Information
Summary:A seal arrangement for sealing an annular gap between a high-pressure steam space and an adjacent low-pressure steam space. The gap is defined between two turbine casings each split into two casing halves, the seal arrangement has a seal element which is formed in a segmented and annular manner and extends between the two turbine casings and engages in an annular receiving groove by means of at least one of its radial end regions. The seal arrangement has at least one segmented ring with a first circumferential surface releasably attached to one of the turbine casings in the region of the annular gap, and has an opposite second circumferential surface with the annular receiving groove or, in a one-piece form, with the radially projecting annular seal element.
