ABSTRACT:
A multi-cylinder combustion structure for an oil burner capable of permitting a red-heated section of a double combustion cylinder to be uniformly red-heated while ensuring complete combustion irrespective of the amount of combustion, to thereby exhibit satisfactory aesthetic and handling characteristics. The structure includes a central cylinder which is provided with a plurality of circumferentially-extending strip-like perforated sections and a plurality of circumferentially-extending strip-like non-perforated sections in a manner to vertically alternate with one another. Therefore, even when the wick is lowered to decrease the amount of combustion to a degree sufficient to cause the upper end of a combustion flame to be positioned in the gap of the double combustion cylinder, the upper portion of a red-heated section of the double combustion cylinder is rendered uniformly dark and the lower portion thereof is rendered uniformly red-heated while ensuring that the boundary between both portions is circumferentially uniformly defined.
