Abstract (en)
[origin: US2015110620A1] A seal arrangement (15; 26; 43; 50) for sealing an annular gap (14) between a high-pressure steam space (12) and an adjacent low-pressure steam space (13). The gap is defined between two turbine casings (10, 11) each split into two casing halves, the seal arrangement (15; 26; 43; 50) has a seal element (24; 47; 58) which is formed in a segmented and annular manner and extends between the two turbine casings (10, 11) and engages in an annular receiving groove (9, 23; 30, 34; 49; 54) by means of at least one of its radial end regions. The seal arrangement (15; 26; 43; 50) has at least one segmented ring (16, 20; 27, 31; 44; 51; 55) with a first circumferential surface (17, 21; 28, 32; 45; 52, 56) releasably attached to one of the turbine casings (10, 11) in the region of the annular gap (14), and has an opposite second circumferential surface (18, 22; 29, 33; 46; 53, 57) with the annular receiving groove (9, 23; 30, 34; 54) or, in a one-piece form, with the radially projecting annular seal element (47; 58).
