Abstract: Disclosed is a crop-drying oil burner particularly adapted to be used outdoors when ambient temperatures are below about 45* F. This burner includes an inner cylindrical combustion chamber, and a concentric outer air chamber spaced from the inner chamber and including a spaced front plate which covers the open front end of the inner chamber. This front plate has a circular orifice therein which allows flame to shoot out of the inner chamber. High-velocity air is blown through the inner chamber and through the gap between the inner and outer chambers, sweeping across the front plates'' inside surface, keeping it free of carbon.

Abstract: This burner includes a cylindrical combustion chamber, and means which blow air through the chamber. A circular opening in the chamber''s front plate and a plurality of peripheral apertures and radial slits in the chamber''s rear plate allow air to pass through the chamber. Pitched blades adjacent the slits cause this moving air to form a vortex within the chamber, and when oil is injected into the vortex and ignited, a clean, smoke-free flame shoots out the circular opening. If a centrifugal fan is used as the air blowing means, the chamber is ideally located in the quiet zone opposite the fan''s hub. In this instance, air intercepting and directing means collect some air from the peripheral air stream generated by the fan, and direct this intercepted air into the chamber.
