Abstract

Bei einer airblast-Zerstäuberdüse (2) für den Betrieb eines mit flüssigen und gasförmigen Brennstoffen (4, 6) betriebenen Brenners (1) wird die Zwischenwand (18) zwischen innerem (14) und äusserem Luftkanal (13) über innere und äussere Stützelemente (21) gehalten, welche einen Schiebesitz (28) aufweisen und als Drallschaufeln ausgebidet sein können. Die Zerstäuberkanten (19) der airblast-Düse (2) sind in Richtung Düsenachse (11) abgewinkelt. Die Düse zeichnet sich durch geringe Abmasse, niedrigen Druckverlust und geringe Verkokungsneigung aus.

Figure 00000001
In the case of an airblast atomizer nozzle (2) for operating a burner (1) operated with liquid and gaseous fuels (4, 6), the partition (18) between the inner (14) and outer air duct (13) via inner and outer support elements ( 21), which have a sliding seat (28) and can be designed as swirl blades. The atomizer edges (19) of the airblast nozzle (2) are angled in the direction of the nozzle axis (11). The nozzle is characterized by its small dimensions, low pressure drop and low tendency to coke.
