Abstract

Heizkessel mit integrierter Abgasrezirkulation für die Verbrennung von flüssigem oder gasförmigen Brennstoff mit einem in Strömungsrichtung offenen Feuerraumeinsatz (7) und einem stirnseitig angeordneten Brenner, in dessen Flamme ein Teil des Rauchgases zur Kühlung der Flammentemperatur und damit Herabsetzung der NOx-Bildung dadurch zurückgeführt wird, daß im Sinne einer insgesamt optimierten Temperaturcharakteristik der der Flamme zugeführte Rauchgasteil nach einer ersten Abkühlstrecke (16,18) abgegriffen und in einen zylinderrohrförmigen Bereich um die Flammenbildungszone (5) herum geführt ist.
