Abstract

L'INVENTION CONCERNE UN PROCEDE DE DIMINUTION DE L'EMISSION DE COMPOSES AZOTES DE FORMULE GENERALE NO AU COURS DE LA COMBUSTION DE COMBUSTIBLES AZOTES EN BRULEUR CLOS, DANS LEQUEL L'ADDITION D'AIR DE COMBUSTION S'EFFECTUE EN DEUX PHASES, L'UNE SOUS-STOICHIOMETRIQUE ET L'AUTRE SUR-STOICHIOMETRIQUE, ET DANS LEQUEL LE COURANT D'AIR SECONDAIRE EST FRACTIONNE EN UN COURANT 3 AMENE DIRECTEMENT AU BRULEUR POUR FORMER UNE ZONE PRIMAIRE SOUS-STOICHIOMETRIQUE 6, ET EN UN COURANT 4 AMENE DANS LE FOYER A L'EXTERIEUR DE LA FLAMME DU BRULEUR DANS LA REGION DE LA ZONE SECONDAIRE SUR-STOICHIOMETRIQUE 7.THE INVENTION CONCERNS A PROCESS FOR REDUCING THE EMISSION OF NITROGEN COMPOUNDS OF GENERAL FORMULA NO DURING THE COMBUSTION OF NITROGEN FUEL IN A CLOSED BURNER, IN WHICH THE ADDITION OF COMBUSTION AIR IS MADE IN TWO PHASES. ONE SUB-STOICHIOMETRIC AND THE OTHER SUB-STOICHIOMETRIC, AND IN WHICH THE SECONDARY AIR STREAM IS FRACTIONATED INTO A CURRENT 3 BRINGS DIRECTLY TO THE BURNER TO FORM A PRIMARY SUB-STOICHIOMETRIC AREA, AND IN A STREAM 4 PROVIDES IN THE FIREPLACE OUTSIDE THE BURNER FLAME IN THE REGION OF THE SUR-STOICHIOMETRIC SECONDARY ZONE 7.
