This invention relates to improvements in oil
burners and has for an object the provision of
means to compact the pilot lire and to effect a
reduction in the oil consumption during pilot lire.
These and other objects will be more fully set
forth and made apparent in the following de
scription and in the accompanying drawing.

Located above the turbulator ring `and mounted
upon the top of the pot is a centrally apertured
plate I8 and over the aperture thereof is a rotor
plate I9 which is provided with the vanes I 9a
to impart rotation to llames issuing from the pot
at high i’ire.
