A method for producing a fuel lance for a burner, in particular for a gas turbine burner, has at least the following steps: creating a fuel lance body having a tip that has a cooling air duct, which opens into an exit opening extending around a longitudinal axis of the fuel lance body, and a nozzle face, which is arranged around the exit opening and has a plurality of fuel nozzles; determining a spatial distribution of a heat input, to which the nozzle face is subjected during operation when a fuel flowing out through the fuel nozzles is burnt; and applying a thermally insulating layer onto the nozzle face in accordance with the spatial distribution of the heat input. A fuel lance is produced with the method. A burner has such a fuel lance. |
