PROBLEM TO BE SOLVED: To provide a structure of a pressure atomizing oil burner capable of improving combustion characteristics by suppressing a rise in pressure in an air blow tube. SOLUTION: A bottom cylindrical combustion tube 3 is disposed in the air blow tube 2 to which combustion air is fed by a combustion fan 1, a large number of air supply ports 3a are formed in the side wall of the combustion tube 3, a fuel inlet 4 is formed at the center of a bottom plate, a swing vane 5 is installed around the fuel inlet 4, and a fuel spray nozzle 7 is fitted facing the fuel inlet 4. A control tube 8 formed of a small diameter front tube 8a surrounding the fuel spray nozzle 7 and a large diameter rear tube 8b is installed between the bottom plate of the combustion tube 3 and the bottom plate of the air blow tube 2, and an air hole 8c is formed in the side wall of the front tube 8a. The outlet 1a of the combustion fan 1 is opened in the rear side wall of the air blow tube 2 disposed in the control tube 8, and the combustion air of the combustion fan 1 is blown toward the front tube 8a and the rear tube 8b.
