STABILIZING DEVICE OF POT-TYPE OIL BURNER

PROBLEM TO BE SOLVED: To keep a stable combustion condition over a long time by improving the durability of a stabilizing device installed in a pot of a pot-type oil burner. SOLUTION: A bottomed cylindrical pot 2 with multiple air vents 2a formed in its side wall is installed in a wind tunnel 1 for feeding combustion air, and a disc-like blue-flame cap 3 is disposed in the upper part in the pot 2. In the blue-flame cap 3, a tubular part 3b extending downward from the circumference of its upper surface and a ring-like circumferential part 3c surrounding the tubular part 3b are formed by bending the lower part of the tubular part 3b toward the outside upper part. A mixed gas generated by burning oil below the blue-flame cap 3 is burnt, in the form of blue flame, in the outward side part of the bent circumferential part 3c of the blue-flame cap 3, and since the circumferential part 3c used as a combustion region is reinforced by the bent shape, its deformation is prevented from easily occurring by heat even in long- term usage. A small hole 3a is brought close to the combustion region and the mixed gas passing the small hole 3a is completely burnt in a short time so that smell in ignition is restrained.
