METHOD FOR REDUCING THE CONTENT OF NITRIC OXIDES IN INDUSTRIAL BOILER COMBUSTION GASES AND THE BURNER FOR CARRY OUT THIS METHOD

摘要

The present invention relates to a process for reducing the nitrogen oxide content of flue gas from an industrial boiler and to a burner for carrying out the process. The method, which also burns the fuel in a boiler with burnt burner burners, in particular in an industrial boiler, arranged in horizontal densities in the wall (7) of the combustion chamber (15), from which the burners are superimposed on one another, is carried out with at least one pair of burners located at least one burner and at least one burner stream of at least one burner, downwards in the direction of fraying of the air and fuel mixture of at least one burner in the lower mud it is guided bitterly as air is directed upwards from the holder of the burners in the upper barrel to the firing zone. The burner having a central cylindrical nozzle (1) connected to a coal milling mill (24) connected to a coal milling mill (24) through a fuel conveying cylindrical shape extending from one end to the combustion chamber (15), from which the central lance (1) 2) it is formed by its essence, heat, located at the end of the central barbell (1) with the conical surface defined by the conical surface at the end of the central barbell (1) arranged along the thermal axis of the central barbell (1); ), from which the apex angle of the cone face of the adiffuser (3) is equal to the apex angle of the tapered cone (5) defining the opening (4) in the wall (7) of the combustion chamber (15). ŕ
