Abstract

Zur Reduzierung des Sauerstoffpartialdruckes und damit zur Verminderung der Stickoxidbildung soll einem atmos­ phärischen Gasbrenner Abgas zugeführt werden (Abgasrück­ führung). Dieses erfolgt in einem gemeinsames Luftkanal (5) für die Primärluft mit einer einstellbaren oder kalibrierten Zuluftöffnung (5a) und mit Abgasansaugstutzen (5b, 5c) der in den Saugbereich des Brennstoffes zwischen Brennerdüse (2) und Brennerrohr (3) mündet. To reduce the oxygen partial pressure and thus To reduce the formation of nitrogen oxides, an atmos aspherical gas burner exhaust gas (exhaust gas return guide). This takes place in a common air duct (5) for the primary air with an adjustable or calibrated Supply air opening (5a) and with exhaust gas intake (5b, 5c) into the suction area of the fuel between the burner nozzle (2) and burner tube (3) opens.
