    Abstract: With a method and burner (10) for staged combustion of a fuel in gaseous form, three distinct streams of, respectively, a premixed mixture of fuel and combustion air, pure combustion air and pure fuel are introduced into a combustion space (16) at different radial positions (70; 80; 90), viewed from the axis of the burner. As a result thereof, several combustion zones (O; C; D) and mixing zones (A; B; C) can be distinguished in the combustion space (16). The combustion conditions in these zones are such that in each case such a substoichiometric amount of either fuel or oxygen is present locally or such a dilution of the combustion gases with flue gases is present that combustion takes place at low temperature and thus the emission of harmful nitrogen oxides is limited.
