Abstract (en)

[origin: EP0914869A2] The jet (10) has at least three concentric flow channels each leading to a gap-type mouth aperture. One mouth gap (32) spraying a liquid is surrounded on both sides by other gaps (30, 34) for gas output. The gap width (42) of the mouth gap for spraying the liquid is 0.22-2.2 mm wide. The gap width (40, 44) of the gap for gas output is 0.3-2.3 mm. The ratio between the spray mouth gap width and the length of the surrounding gap is between 1:50 and 1:5000.
