Latest Patents

Ralf Ziwes holds a patent for a seal arrangement designed to seal an annular gap between a high-pressure steam space and an adjacent low-pressure steam space. This gap is defined between two turbine casings, each split into two casing halves. The seal arrangement features a segmented and annular seal element that extends between the two turbine casings and engages in an annular receiving groove through at least one of its radial end regions. The design includes at least one segmented ring with a first circumferential surface that is releasably attached to one of the turbine casings in the region of the annular gap. The opposite second circumferential surface is equipped with the annular receiving groove or, in a one-piece form, with the radially projecting annular seal element. This innovative solution enhances the efficiency and reliability of turbine operations.
