負荷燃焼を行うには限界がある。(Prior Art) Conventionally, a gun-type burner widely used as a simple oil burner is composed of an injection nozzle and a disc or conical diffuser (flame holding plate), and a nozzle located at the center of the diffuser. The sprayed oil droplets are agitated by vortices and turbulence, and are mixed with combustion air and burned in the combustion chamber. In this case, the diffuser provides a flame holding effect by forming a low flow velocity region in the rear part and generating a swirling flow by the swirling slit. The flame generated by this burner is a long flame and poorly organized, and there is a limit to performing high-load combustion.

There is a burner to make. This burner swirls the air flow in the cylinder, so the combustion and swirling air flows are mixed very well,
Combustion with a low oxygen ratio was possible, and since the two-stage combustion was performed, the combustion temperature in each combustion chamber could be lowered and NOx could be reduced. However, the combustion chamber used in this burner has a cylindrical shape to form a swirling air flow in the combustion chamber, and it is necessary to make a tangential hole in the outer peripheral wall, which is a very difficult task to manufacture. Had to do. Further, in order to form a tangential hole that gives a swirling flow, it is necessary to make the wall thickness of the cylindrical wall large.

A square-shaped ring (9) is connected to one end of a cylindrical combustion cylinder outer cylinder (1), and the other end is connected to a blower. The combustion air sent by the blower is the combustion cylinder inner cylinder (2). ), And flows into the furnace through the air holes (4). Further, the combustion air passes through the air hole (5) of the combustion cylinder inner cylinder (2), then swirls in the combustion cylinder inner cylinder (6) and then flows into the furnace. Atomizing nozzle (7) above the air hole (4) of the combustion cylinder inner cylinder (2)
Is connected to an oil pump by an oil supply pipe (8), and fuel pressurized by the oil pump is sprayed by a spray nozzle (7) and ignited by a spark emitted by an ignition device (3). The combustion air ejected from the air holes (5) forms a swirl flow while intersecting with the combustion air in the air holes (5) on the other surface, intersects at right angles with the flow of the sprayed oil droplets, and inside the combustion cylinder.
