Abstract

Bei einem Brenner für einen Wärmeerzeuger, der im wesentlichen aus einem Drallerzeuger (100a) für einen Verbrennungsluftstrom (115) und aus Mitteln zur Eindüsung eines Brennstoffes in diesen Verbrennungsluftstrom besteht, ist stromab des erwähnten Drallerzeugers eine Mischstrecke (220) angeordnet. Diese Mischstrecke weist innerhalb eines ersten Streckenteils (200) eine Anzahl von in Strömungsrichtung verlaufenden Uebergangskanälen (201), welche die nahtlose Ueberführung der im Drallerzeuger (100a) gebildeten Strömung (40) in ein nachgeschaltetes Rohr (20) sicherstellen. Eine zur Eindüsung eines Brennstoffes kopfseitig und auf der Brennerachse (60) angeordnete Düse (103) ist gegenüber dem Anfang des Drallerzeugers um eine Strecke stromauf versetzt.

Figure 00000001
In a burner for a heat generator, which essentially consists of a swirl generator (100a) for a combustion air stream (115) and means for injecting a fuel into this combustion air stream, a mixing section (220) is arranged downstream of the swirl generator mentioned. Within a first section (200), this mixing section has a number of transition channels (201) running in the direction of flow, which ensure the seamless transfer of the flow (40) formed in the swirl generator (100a) into a downstream pipe (20). A nozzle (103) arranged on the head side and on the burner axis (60) for injecting a fuel is offset upstream a distance from the start of the swirl generator.
