を有していた。Prior art and its problems This type of gun-type burner sprays oil from a nozzle to atomize it, and ignites and burns the atomized oil.As a device for complete combustion, a combustion tube is used. The oil is ejected from the nozzle towards the rotating scattering plate installed inside, and the oil is ignited and first heats the rotating scattering plate, and then the ejected oil is heated and becomes a fine mist and vaporizes, producing a blue flame. A configuration in which combustion is performed is known, but in this case, in order to simplify the rotation mechanism, the rotating scattering plate and the near blower for supplying combustion air are mounted on the same axis, so the near blower is inevitably an axial flow with a large fan diameter. Since the device becomes a fan, the entire device is complicated and large, and the manufacturing cost is high.

なる。The air volume control valve 19 is opened and an appropriate amount of fuel air is injected into the injection nozzle device 1. When air is blown into the i44 and then the fuel pump 20 is operated to open the injection nozzle 5, oil is ejected from the injection nozzle 5 at a constant ejection angle and hits the annular collision wall 16 provided in the tapered vaporization cylinder 14. As it collides with the inner circumferential surface, the oil flows turbulently through the concave portion 24 on the front surface and is sufficiently atomized, filling the vicinity of the concave portion 24 . collides with the inner surface of the container and becomes atomized. Therefore, when the ignition electrode 6 is ignited, the atomized oil burns and heats the contact surface to a high temperature in a short time, and then the injected oil receives latent heat from the annular collision wall 16 and the like and vaporizes. At the same time, the vaporized oil flows from the hollow cylindrical body 12 for vaporization to the inner surface of the combustion tube 11, and flows out along the outer periphery of the hollow cylindrical body 12 in the direction of the solid line arrow in the figure. It is combusted by heat radiation from the surface, and in the combustion section 22 in contact with the high-temperature annular collision wall 16 surface, it is combusted by the combustion air that has flowed in from the engine section 4 together with the oil, and flows out into the gas air passage 10. The combustion gas flows through the exhaust pipe 8 and is exhausted to the outside of the machine through the exhaust port 9.

する。DETAILED DESCRIPTION OF THE INVENTION According to the present invention, as described above, a tapered vaporizing cylinder having an annular collision wall is connected to a hollow cylinder for vaporization fitted inside a combustion cylinder consisting of a cup-shaped cylinder, and Since the vaporized oil is injected from the vaporizing cylinder into the inside of the combustion cylinder through the hollow cylinder for vaporization and burns with green flame in the combustion section, the device structure is simple and compact, and does not have to be complicated and large as described above. The drawbacks of the conventional device can be completely eliminated, and the oil vaporized by the latent heat from the inner surfaces of the annular collision wall and the hollow cylinder for vaporization is removed by heat radiation from the outer surfaces of the collision wall and the hollow cylinder. Since it burns, green flame combustion can be carried out reliably and combustion efficiency can be improved, and there are also effects such as less generation of soot and less combustion noise, making it possible to maintain a good working environment.
