PROBLEM TO BE SOLVED: To provide an oil combustion device capable of feeding air when fuel is burned for performing combustion in an optimum state of air feed. SOLUTION: The oil combustion device comprises a burner cone 50 having at least two different diameters of a small diameter part and a large diameter part and at least two blowers of a first blower 30 to feed air to mainly the small diameter part 51 of the burner cone 50 and a second blower 40 to feed air mainly to the large diameter part 52 of the burner cone in the oil combustion device to spray oil in the burner cone for combustion. Air to the small diameter part 51 of the burner cone is fed and regulated by the first blower 30 and air to the large diameter part 52 of the burner cone is fed and controlled by the second blower 40. In a region where a combustion amount is low, an air amount is regulated by mainly the first blower 30 and in a region where a combustion amount is high, an air amount is regulated by the second blower 40.
