The invention relates to a method for burning a fluid fuel, in which fuel is reacted in a catalytic reaction, whereupon catalytically pre-reacted fuel continues to be burned in a secondary reaction. A swirling component is impressed onto the pre-reacted fuel, allowing the secondary reaction to be ignited in a spatially controlled manner, resulting in complete burnout. The invention further relates to a burner for burning a fluid fuel, in which the fuel outlet of a catalytic burner is disposed upstream of the fuel outlet of a primary burner in the direction of flow of the fuel within a flow channel such that the fuel is catalytically reacted. The catalytic burner is provided with a number of catalytically effective elements which are arranged such that a vortex is created in the flow channel. The invention can be applied particularly to combustion chambers of gas turbines.

There is described a method for operation of a burner, whereby a fuel is supplied to the burner, sprayed into the combustion air, mixed with the combustion air to give a fuel/air mixture and burnt in a combustion chamber. With regard to a combustion particularly low in pollutants and, in order to reduce the nitrogen oxide emissions with relation to achieving a given nitrogen oxide emission level, a change in parameters characterizing the fuel is determined. Such a parameter may, for example, be the Wobbe index. There is further described a device for carrying out said method, comprising a fuel treatment device, with an analytical device for the analysis of the current fuel composition and a monitoring and control system.
