Abstract

Die Erfindung betrifft einen Blaubrenner für die Bestückung von Heizkesseln, bestehend aus einer gebläsebestückten Verbrennungsluftzuführung (1), an deren Ende eine mit Luftdurchströmöffnungen (2) versehene, Verbrennungsluftblende (5) angeordnet ist, an die sich ein mit mindestens einer Abgasrückführöffnung (6) in Höhe des Anordnungsbereiches der Brennstoffdüse (3) eines Düsenstockes (4) versehenes, brennkammerseitig offenes Flammrohr (7) anschließt, wobei die von einem Gebläse (G) und den Luftdurchströmöffnungen (2) repräsentierte Verbrennungsluftzuführung (1) und die Bemessung der Abgasrückführöffnungen (6) derart ausgelegt sind, daß das Flammrohr über den wesentlichen Teil seiner Länge (L) als Vormisch- und Vorverdampfungsrohr wirkt. Nach der Erfindung sind am düsenfernen, gegen die Heizkesselbrennkammer (B) axial offenen Endbereich (7') des Flammrohres (7) diesen Endbereich im wesentlichen offen lassende Mittel (8) zur Flammstabilisierung angeordnet.

The invention relates to a blue burner for equipping boilers, comprising a blower-equipped combustion air supply (1), at the end of which a combustion air screen (5) provided with air flow openings (2) is arranged, to which there is at least one exhaust gas recirculation opening (6) Height of the arrangement area of the fuel nozzle (3) of a nozzle block (4) provided with the combustion chamber open flame tube (7), the combustion air supply (1) represented by a blower (G) and the air flow openings (2) and the dimensioning of the exhaust gas recirculation openings (6) are designed so that the flame tube acts as a pre-mixing and pre-evaporation tube over the major part of its length (L). According to the invention, means (8) for flame stabilization which essentially leave open this end region are arranged on the end region (7 ') of the flame tube (7) remote from the nozzle and axially open towards the boiler combustion chamber (B).
