摘要： The present invention relates to a turbine system (100), in particular a steam turbine system. The turbine system (100) has a turbine shaft (105), a first turbine region (101) and a second turbine region (102) which is arranged downstream of the first turbine region (101) in the axial direction (106) of the turbine shaft (105). Furthermore, the turbine system (100) has a casing (110) with an outer wall (113), a first dividing wall (111) and a second dividing wall (112). The first dividing wall (111) is at such a distance from the second dividing wall (112) in the axial direction (106) that a space (104) is formed which is defined at least by part of the outer wall (113), the first dividing wall (111) and the second dividing wall (112). A first working medium (A1) flows at a first working pressure (P1) from the first turbine region (101) into the space (104) and a second working medium (A2) flows at a second working pressure (P2) from the second turbine region (102) into the space (104), such that a fluid mixture (Fm) of the first working medium (A1) and the second working medium (A2) can be produced in the space (104).

摘要： In order to obtain specially high live steam parameters (live steam temperature, live steam pressure) in a steam turbine, the admission (1) of a turbine housing has a flanged joint (4, 5) on the inside comprising multiple through-flow openings (7). Said flanged joint is used to fix a valve housing (2) for control valves (3) and has a sealing surface (15) encompassing each of the through-flow openings (7). In order to provide a particularly reliable sealing, high surface pressing is achieved in the sealing area by providing a shaped outer contour (16) of the sealing surface (15) in the area between adjaent through-flow openings (7) and by appropriately arranging different sized screws (6) along said shaped outer contour (16).
