Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gun-type burner for vaporizing combustion that vaporizes oil such as kerosene and burns it with blue flame.

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, after which the ejected oil is heated, becomes a fine mist, vaporizes, and burns as a blue flame. However, in this case, in order to simplify the rotation mechanism, the rotating scattering plate and the air blower for supplying combustion air are mounted on the same axis, so the air blower is inevitably an axial fan with a large fan diameter. As a result, the entire device is complicated and large, and the manufacturing cost is high.

Purpose of the Invention In view of the above-mentioned drawbacks, the present invention simplifies the device structure, completely eliminates the drawbacks of the conventional device which is complicated and large, and also improves combustion efficiency by always performing green flame combustion reliably. The purpose of the present invention is to provide a high-performance gun-type burner for vaporization combustion that improves the performance.

Structure of the Invention The gun-type burner for vaporization combustion of the present invention includes a combustion tube made of a cup-shaped cylinder provided inside a combustion gas discharge tube through a gas air passage, and a combustion tube made of a hollow cylinder made of a hollow cylinder provided inside the combustion gas discharge tube. A collision body is inserted and fixed in a loosely fitted manner, and an injection nozzle device connected to a blower device is installed so as to spray vaporized oil into the inside of the combustion cylinder through the hollow solid body of the collision body. It has a configuration characterized by being formed .

Description of examples The configuration of the present invention will be explained based on the drawings.

Reference numeral 1 denotes an injection nozzle device, and the nozzle device 1 has a machine part 4 provided with a discharge port 2 on one side and an air intake port 3 on the other side.
An injection nozzle 5 and an ignition electrode 6 are disposed inside the engine, and a blower device 7 is connected to the air intake port 3. Reference numeral 8 denotes a combustion gas exhaust pipe having an exhaust port 9 on one side; a combustion pipe 11 made of a cup-shaped cylinder is provided inside the discharge pipe 8 via a gas air passage 10; The open side of the cylinder body is installed facing the nozzle device 1, and a vaporizing collision body 13 consisting of a hollow cylinder body 12 is fitted into the combustion cylinder 11 and fixed in a loose-fitting manner. The cylinder body 12 has its terminal end connected to the discharge port 2 of the nozzle device 1, and its front end cylinder wall serves as a collision cylinder wall part 13, and a cylinder 14 supplies liquid fuel such as kerosene to the injection nozzle 5. 15 is an air volume control valve for adjusting the fuel air mass sent to the machine section 4, 16
17 is the skirt portion of the combustion tube 11, and 17 is the skirt portion 16.
The combustion part 18 formed between the hollow cylinder 12 and the hollow cylinder 12 is a support rod of the hollow cylinder 12.

The operation of the above configuration will be explained below.

When the air volume control valve 15 is opened to send an appropriate amount of fuel air into the machine part 4 of the injection nozzle device 1, and then the combustion pump 14 is activated to open the injection nozzle 5, a constant amount of air is emitted from the injection nozzle 5. The oil jets out at an angle and collides with the inner peripheral surface of the collision wall 13 at the front end of the hollow cylinder 12, and a part of it collides with the inner bottom surface of the combustion tube 11, and the atomized oil is scattered around the area. filled with. Then, when ignited by the ignition electrode 6,
The atomized oil burns and heats the collision cylinder wall 13 and a part of the combustion cylinder 11 surface to a high temperature in a short time, and the subsequently injected oil receives latent heat from the collision cylinder wall 13, etc. At the same time, the vaporized oil flows out along the inner surface of the combustion tube 11 along the outer periphery of the hollow cylinder 12 in the direction of the solid line arrow in the figure, and during this time, it is burned by heat radiation from the outer peripheral surface of the cylinder 12. In the combustion section 17 of the combustion tube-skirt section 16, a green flame is combusted by the combustion air that has also flowed in from the engine section 4, and the combustion gas flows out into the gas air passage 10, and the combustion gas flows through the combustion gas exhaust tube 8. It will be expelled from the machine through the exhaust port 9.

Claim No. (R) is (Fig. 2).

(See Fig. 3) Since the combustion tube 11 is provided with radial protrusions 19 on its inner peripheral surface, the latent heat surface of the inner circumference of the combustion tube 11 expands to activate the vaporization action, and the vaporized oil is spread radially. This has the effect of smoothing the flow state by rectifying the flow, ensuring green flame combustion, and improving combustion stability.

Claim (3) provides that the combustion tube 11 is provided with the combustion porous wall plate 20 on the open surface of the cylinder end, so that the entire surface of the porous wall plate 20 is Each through hole 21・
The flame of blue flame combustion is ejected evenly from ..., preventing uneven ejection of the flame, and has the effect of keeping the combustion temperature uniform and well over the entire surface.

It should be noted that the structure of the combustion tube, vaporization colliding body, etc. of the present invention is not limited to the drawings, and can of course be modified as appropriate. In some cases, a plurality of openings are provided on the circumferential surface, and flame is ejected from each opening to the side of the combustion cylinder to perform blue flame combustion.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, as described above, a vaporizing collision body made of a hollow cylinder is fitted inside a combustion cylinder made of a cup-shaped cylinder, and Since the vaporized oil is injected into the combustion tube and combusted, the device structure is simple and compact, completely eliminating the drawbacks of the conventional devices that are complicated and large. It vaporizes and burns by heat radiation outside the cylinder, so green flame combustion is reliably carried out and combustion efficiency can be improved, and it also has the effect of maintaining a good working environment without generating soot or combustion noise. .
