TITLE OF THE INVENTION: METHOD OF REDUCING THE NOx EMISSIONS DURING COMBUSTION OF NITROGEN-CONTAINING FUELS ABSTRACT OF THE DISCLOSURE: A method of reducing the NOx emissions during combustion of nitrogen-containing fuels via burners in a closed combustion chamber. Fuel and air for com- bustion are supplied in stages to the burner flame as partial flows via delivery devices which are separate from one another. The method is carried out in three stages, by generating, in a first stage, at at least slightly less than stoichiometric conditions, a primary flame having at least half of the total output; by supplying, in a second stage, an increment of fuel with a fluid to the primary flame down stream therefrom and at a time interval from the first stage generation, and initiating a combustion of the increment of fuel with residual oxygen from the primary flame or with oxygen from the fluid, with the last-mentioned combustion resulting in a mixture of flue gas and unburned fuel; and, in a third stage, which is a zone for the combus- tion of what remains, by thoroughly mixing and burning the mixture of flue gas and unburned fuel from the second stage with a strong jet of an increment of air for combustion.
