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 ().

Seal arrangement

A method for flushing a section of a fuel system of a burner of a gas turbine is provided. The method includes the steps of providing a feed line for feeding fuel from a fuel source to the burner, providing a first feed point close to the burner and a second feed point remote from the burner in the feed line in each case for feeding a medium into the feed line, feeding the medium via the first feed point, and discharging, via the burner, the fuel which is in the feed line between the first feed point and the burner, and also feeding the medium via the second feed point, and discharging, via the first feed point, the fuel which is in the feed line between the second feed point and the first feed point.
