A burner, particularly for a gas turbine, includes a catalytic combustion chamber and a performer/reformer (24). The combustion chamber has an essentially cylindrical extent in a flow direction of a fuel and a catalytically active coating (12) on a wall facing the fuel for oxidation of the fuel. A particularly low nitrogen oxide content of burner exhaust gas is achieved as a result of the catalytically induced combustion of the fuel. At the same time, in contrast to known primary measures for nitrogen oxide abatement, the flow resistance in the burner is not increased by the coating of the wall. Therefore, when the burner is used in a gas turbine, a particularly high efficiency together with a low nitrogen oxide emission can be achieved.

[ We claim:] [1.] A burner, comprising:a catalytic preforming stage for conducting a flow of a fuel partstream therethrough and for at least partly breaking down the fuel partstream into substances igniting readily; anda catalytic, continuous combustion chamber for receiving a fuel including a main fuel stream, the preformed fuel partstream and air, the preformed fuel partstream being fed directly into said catalytic combustion chamber, said combustion chamber having a substantially cylindrical wall extending in an axial flow direction of the fuel, said wall facing the fuel and having axially spaced bores formed therein for introducing the preformed fuel partstream through said bores into said combustion chamber and a catalytically active coating on said wall for oxidizing the fuel.
