Abstract
1447584 Mixing flowing fluids OERTLI STANDARD AG 6 Feb 1974 [8 Feb 1973] 5538/74 Heading B1C [Also in Division F4] A burner head for mixing liquid fuel with combustion air comprises a number of fixed guide vanes 15 for directing the air as a swirling flow into an outwardly-flared mixing region located above the vanes as seen in the drawing, and a central nozzle (19), Fig. 2 (not shown), for injecting atomised fuel into the mixing region as a swirling flow contrarotational to that of the air. The vanes overlap by at least 30% and up to 50% of the projected area of each vane. The passages between the vanes converge in the direction of flow and discharge the air at an angle of between 7 and 20 degrees to a plane perpendicular to the axis 3. A number of groups of at least two holes 10 allow additional air to be directed into the mixing region. The holes may be closed as by discs or asbestos inserts. The outer casing may be extended at its downstream end as shown in broken lines. In use, the inner wall 6 becomes heated and serves as a vaporiser. Inturned flange 8 turns back unburnt fuel particles hurled outwardly from the flame.
