Claims

[Claims for Utility Model Registration] 1. A small-diameter inner cylinder is disposed inside the outer cylinder through an air passage that is ventilated by a blower, and a primary air inlet that communicates with the air passage is provided on the rear end surface of the inner cylinder. At the same time, a variable flow rate atomizer for liquid fuel is installed near the rear end face of the inner cylinder with the spray nozzle on the front side, and a swirler having a swirl vane is installed on the front side of the spray nozzle, In the burner, the inner cylinder on the front side of the swirler is provided with multiple rows of secondary air inlet ports each having a plurality of openings in one row in the circumferential direction, in the front central part of the swirler, It is characterized by providing an aperture plate whose center hole diameter is smaller than the center hole diameter of the swirler, and whose outer periphery is larger than the center hole diameter of the swirler and smaller than the outer diameter of the swirling blades of the swirler. Oil burner with variable combustion rate. 2. The variable combustion amount petroleum burner according to claim 1, wherein the throttle plate has swirl vanes cut and raised on the outer periphery of its center hole. 3. The variable combustion amount oil burner according to claim 1 or 2, wherein the variable flow rate atomizer is a return type pressure spray nozzle in which the flow is returned to the leveler side via a return flow rate regulating valve. 4. A water heater comprising the variable combustion amount burner according to claim 1, 2 or 3. 5. A bathtub with hot water supply equipped with the variable combustion amount burner according to claim 1, 2 or 3.
