The formation of nitrogen oxides during the operation of burners for solid, liquid, and gaseous fuels is reduced by means of an exhaust gas feed-back system. The exhaust gases are injected into a combustion chamber through openings provided in the region of stabilizer via a flame pipe and, by choice, also around the flame pipe. Preferably, the combustion air as well as the exhaust gases are activated by an active aerosol. The exhaust gas feed-back is effected by means of a longitudinally slidable adaptor pipe and an adaptor pipe shoulder enclosing the flame pipe at least partly. The regulation of the exhaust gas streams is achieved by displacing the adaptor pipe and the adaptor pipe shoulder.
