Abstract

PROCEDE ET DISPOSITIF POUR LA REALISATION DE LA COMBUSTION AVEC UNE TENEUR DIMINUEE EN OXYDES D'AZOTE, DANS LES FUMEES. A LA SUITE D'UNE COMBUSTION INCOMPLETE ON MELANGE AUX GAZ RESULTANTS UN GAZ 5 CONTENANT DE L'OXYGENE, DE FACON A CE QUE LA TENEUR EN OXYGENE DANS LES FUMEES NE DEPASSE PAS 0,3. LES IMBRULES DU COMBUSTIBLE SONT BRULES ENSUITE PAR L'INJECTION DE L'AIR SECONDAIRE 4 EN AVAL DU GAZ 5 SUSINDIQUE. LES PROCEDE ET DISPOSITIF PERMETTENT D'ABAISSER CONSIDERABLEMENT LA TENEUR EN OXYDES D'AZOTE DANS LES GAZ RESULTANT DE LA COMBUSTION DE PRODUITS TELS QUE GAZ NATUREL, HUILE LOURDE, CHARBON, PULPES OU AUTRES.
