Abstract

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.
