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

A method for flushing a section of a fuel system of a burner of a gas turbine, comprising:

• providing a feed line for feeding fuel from a fuel source to the burner;
• providing a first feed point which is close to the burner and a second feed point which is remote from the burner in the feed line in each case for feeding a medium into the feed line via a first feed line or via a second feed line, respectively;
• 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
• 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 into the first feed line,
• wherein the fuel which is discharged into the first feed line is fed into a drainage line which branches off from the first feed line between the first feed point and a second control element, and
• wherein the second control element is provided in a flow connection with the first feed line upstream of the first feed point for adjusting the throughflow to the first feed point,
• wherein a third control element is provided in the second feed line upstream of the second feed point for adjusting the throughflow to the second feed point.
