Description: THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS CLAIHED ARE DEFINED AS FOLLOWS:

1. A liquid fuel burner comprising a firepot having a generally flat base and a cylindrical wall, means for delivering liquid fuel into said firepot, and an air delivery means mounted on said base and extending centrally upwardly in said firepot, said firepot having a plurality of horizontal rows of small passages extending through its cylindrical wall, the small passages of the uppermost of said rows being directed radially upwards, the small passages of the second-uppermost row being directed generally horizontally but at angles to radii drawn through them which induce rotary motion in one direction, the small passages of the lowermost row being directed downward and at angles to radii drawn through them which induce rotary motion in the same direction as the passages of said second-uppermost row, and, intermediate said, second-uppermost row and said lowermost row, at least one additional row, the small passages of said at least one additional row being directed generally horizontally but at angles to radii drawn through them which encourage rotary motion in the opposite direction to that induced by the passages of said lowermost and second-uppermost rows.

2.A liquid fuel burner as defined in claim 1 which includes only one said additional row and is provided with a flame ring located between said one additional row and said second-uppermost row.

3. A liquid fuel burner as defined in claim 1, which includes at least two of said additional rows, and is provided with a flame ring located between the lowermost pair of said additional rows.

4. A liquid fuel burner as defined in claim 1, or 2, or 3, which includes a second flame ring, said second flame ring being disposed above the uppermost of said plurality of horizontal rows of small passages.

5. A liquid fuel burner as defined in claim 1, or 2, or 3, wherein said air delivery means extends centrally upwardly in said firepot to a point intermediate said lowermost row and the next adjacent row.
