Abstract

Bei einem Brenner, insbesondere Kohlenstaubbrenner (1), mit einem Brennstoffförderrohr (7) und einem konzentrisch darin angeordneten Primärluftrohr (9), wobei das Primärluftrohr (9) mündungsaustrittsseitig mit Abstand zu der Mündungsöffnung des Brennstoffförderrohres (7) endet und der Brenner (1) mit einer staubförmigen Brennstoff im Dichtstrom fördernden Zuleitung verbunden oder verbindbar ist, soll eine Lösung geschaffen werden, die es ermöglicht, einen zur Befeuerung des Feuerraums eines Dampferzeugers geeigneten NOx-armen Brenner mit einer Dichtstromförderung des Brennstoffes auszustatten, ohne die NOx-arme Verbrennungseigenschaft des Brenners zu beeinträchtigen. Dies wird dadurch erreicht, dass der Innenraum des Primärluftrohres (9) mit einer Primärluftzuführleitung und der zwischen dem Primärluftrohr (9) und dem Brennstoffförderrohr (7) ausgebildete Brennstoffförderraum (13) mit der dem Brenner (1) staubförmigen Brennstoff im Dichtstrom zuführenden Zuleitung verbindbar oder verbunden ist.

In a burner, in particular pulverized coal burner (1), with a fuel delivery pipe (7) and concentrically disposed therein primary air tube (9), wherein the primary air pipe (9) outlet side with distance to the mouth of the fuel delivery pipe (7) ends and the burner (1) is connected to a dust-like fuel in the dense stream promoting supply line or connectable, a solution is to be created, which makes it possible to equip a suitable for firing the combustion chamber of a steam generator NO x -moving burner with a dense phase promotion of the fuel, without the low NO x combustion property of the burner. This is achieved in that the interior of the primary air tube (9) with a Primärluftzuführleitung and between the primary air pipe (9) and the fuel delivery pipe (7) formed fuel delivery chamber (13) with the burner (1) dust-like fuel in the dense stream feeding supply line connected or connected is.
