Claims
- 1. An atomizing nozzle comprising:an initial atomizer having a generally cylindrical inner surface having an axis, a diameter and a cross sectional area, a first end, a second end, a borehole extending from the first end to the second end, a liquid feed inlet connective with the first end, a plurality of radially distributed atomizing gas inlets through said cylinder; at least one impingement perforate plate atomizer having an imperforate central portion aligned with the axis of said initial atomizer and at least two symmetrically disposed perforations distributed on said plate about said imperforate central portion; a nozzle barrel having an axis and axially aligned with said initial atomizer, a diameter at least twice as large as the diameter of said initial atomizer, a first end connective with said plate atomizer and a second end connective with a nozzle outlet comprising an orifice outlet having an eliptical opening.
- 2. The nozzle of claim 1 wherein two impingement plates are provided, one at said first end of said nozzle barrel and another intermediate said first and second end of said nozzle barrel.
- 3. The nozzle of claim 1 wherein said imperforate central portion has a cross sectional area at least as large as said cross sectional area of said initial atomizer.
- 4. The nozzle of claim 1 wherein said impingement plate has at least four holes each at least ½ inch in diameter.
- 5. The nozzle of claim 1 wherein said impingement plate has three holes each at least ½ inch in diameter.
- 6. The nozzle of claim 1 wherein said impingement plate has a mushroom shape or curved surface on a side of the impingement plate nearest said initial atomizer.
- 7. The nozzle of claim 1 wherein two impingement plates are provided within said nozzle with an impingement plate spacing of at least four inches.
- 8. The nozzle of claim 1 wherein the distance from said initial atomization section to said impingement plate is less than or equal to the diameter of said impingement plate.
