A purging and/or sealing apparatus for conveying a purging and/or sealing fluid to at least one burner of a gas turbine plant. The purging and/or sealing apparatus has a pressure accumulator and a heating device, wherein the pressure accumulator is connected to the at least one burner via a first fluid line, with the heating device connected therebetween. A gas turbine plant and a method for purging and/or sealing has at least one burner and a purging and/or sealing apparatus.

Method and apparatus for purging and/or sealing at least one burner of a gas turbine plant

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.

Method for rinsing a fuel system of a gas turbine and associated fuel system

An optical waveguide with a tubular or hose-like housing is provided, which is used in a high-temperature environment, such as, for example, in a burner. The housing has an input opening, an output opening and a center line extending from the input opening to the output opening. In the interior of the housing, transparent spheres are lined up along with center line. The light is guided on account of the refraction of a light beam upon entering and exiting from the transparent spheres.
