Abstract
A combustion cylinder structure for an oil burner capable of stably carrying out minimum combustion as well as controlling the combustion operation over a wide range. The structure is so constructed that a lower heat-impermeable cylinder of an outermost cylinder construction of a multi-cylinder combustion assembly is provided at the upper end thereof with an inward collar, which is provided at the inner end thereof a cylindrical section for rectifying air introduced through a gap between the cylindrical section and an outer cylindrical member to guide it along the cylindrical member. Also, the collar is provided with through-holes, which are arranged in the circumferential direction to guide air along a heat-impermeable cylinder arranged on the heat-impermeable cylinder, resulting in preventing the generation of a turbulent flow between the outer cylindrical member and the heat-permeable cylinder.
