Description

[Detailed Description of the Invention] This invention relates to an oil-burning burner, and in recent years, many vaporization-type oil-burning burners that gasify and burn fuel have been provided.

This idea automatically performs the process from raw combustion to gasification combustion without installing a heater, and in order to achieve short green flame combustion, a preheating burner is used to obtain uniform vaporized gas in the vaporization cylinder. It was established.

Next, to explain the drawings of an embodiment of this invention, 1 is a deep inverted dish-shaped case body with an opening at the top, the inside is a ventilation chamber 2, and a space is formed at the top, while a base plate 3 is attached. ing.

Reference numeral 4 denotes a combustion tube mounted on the base plate 3 so as to communicate with the air blowing chamber 2 through a ventilation hole 5, and the upper end thereof is slightly bent inward to open a combustion port 6.

Reference numeral 7 denotes a vaporizer cylinder which is provided in the middle of the combustion cylinder 4 and produces vaporized gas on its inner wall, and has a gas vent 8 in the upper part at the center and a plurality of suction holes 9 around which the vaporized gas and part of the combustion air are taken in. A tapered aperture plate 10 with equally spaced holes is attached, and the lower part is narrowed slightly inward to open.

Reference numeral 11 denotes a fuel discharge plate that forms a fuel discharge port 12 below the carburetor cylinder 7 and is positioned so as to cover the same, and a support plate 14 and a plurality of support rods 15 that support the support plate 14 are connected to the motor shaft 13. and is rotatable together with the fuel spray body 16.

Further, the fuel spray body 16 is located within the vaporization cylinder 7, forming a fuel discharge gap 17 above, and has a fuel discharge pipe 18 opened therein.

A pilot combustion chamber 19 is formed between the combustion tube 4 and the vaporization tube 7, and the vaporization tube 7 is heated by live combustion at the start of combustion.

20 is a main combustion chamber which is fixed to the vaporizer tube 7 so as to communicate with the vaporizer tube 7 in a detachable manner, and has a flame port 2 on the side.
1..., a partition plate 23 is attached to the lower part of the interior, and a flow regulating chamber 24 is provided between the partition plate 23 and the aperture plate 10 of the vaporization tube 7 for mixing combustion air and vaporized gas and adjusting the pressure. is formed.

Reference numeral 25 denotes a ring-shaped preheating burner, which has a plurality of small flame ports 26 evenly spaced inward and is positioned at a constant interval on the outer periphery of the lower part of the vaporizing cylinder 7, and its upper end is communicated with a plurality of communication pipes 27. I'm letting you do it.

The preheating burner 25 may be partitioned off individually so that it communicates with the communication pipe 27.
A corresponding number of arc shapes may be combined to form a ring shape.

Also, the upper end of the communication pipe 27 is communicated with the inside of the vaporization cylinder 7,
The vaporized gas flows back to the preheating burner 25.

Further, when gasification combustion is started, the preheating burner 25 heats the vaporization tube 7 instead of the pilot combustion chamber 19.

Also, below the motor shaft 13 is a fan motor 2.
8 and a fan 29 are integrally attached.

30 is an ignition plug located in the pilot combustion chamber 19.

This invention is constructed as described above. Next, the operation of this embodiment will be explained. By starting the fan motor 28, the fan 2
9, the fuel spray body 16, and the fuel discharge plate 11 also rotate, and combustion air flows into various locations as indicated by the arrows.

At the same time, the spark plug 30 starts spark discharge, and after a slight delay, fuel is supplied from the fuel discharge pipe 18 to the fuel spray body 16, and the fuel flows down the inner wall of the vaporization cylinder 7 in the form of a thin film due to the circular force, and the fuel Fuel flows onto the discharge plate 11 and enters the pilot combustion chamber 19 from the fuel discharge port 10.
A mist is sprayed inside.

At this time, since combustion air is being supplied into the pilot combustion chamber 19 and the spark plug 30 is discharging sparks, it is ignited and raw combustion begins, and flame and combustion heat are released from the combustion port 6.

This raw combustion heats the vaporization tube 7 outward, so the fuel ejected from the fuel spray body 16 is vaporized in the vaporization tube 7 and becomes vaporized gas, which is mixed with the inflowing combustion air and flows into the main combustion chamber 20. , Enguchi 21...
Since the flame from the pilot combustion chamber 9, which has been blown outward and has been combusted in advance, is discharged from the combustion port 6, it is ignited by this flame and gasification combustion is performed.

On the other hand, a part of the vaporized gas in the vaporization tube 7 flows into the rectification chamber 24 while mixing with combustion air, and flows into the communication pipe 2.
7 and flows down into the preheating burner 25 and is discharged from the small flame port 26.

As a result, the momentum of the pilot combustion chamber 1 has weakened.
9 ignites and starts combustion, and the outer wall of the vaporizing tube 7 is converted into a pilot combustion chamber 19 and heating starts.

During combustion by the preheating burner 25, since the preheating burner 25 is ring-shaped and is provided on the outer periphery of the lower part of the vaporization tube 7, the small flame opening 2 is connected to the outer wall of the vaporization tube 7.
The flame caused by 6 is licked upward by the rise of combustion air from below, so that the vaporization cylinder 7 is uniformly preheated from below.
The preheating distribution is also averaged, and the vaporization tube 7 itself is also made uniform in a short time.

As a result, the mist of fuel jetted onto the inner wall surface of the vaporizing cylinder 7 is also heated uniformly, and becomes uniform vaporized gas, resulting in full-fledged gasification combustion with a blue flame and a short flame.

As described above, this invention includes a vaporizer tube 7 that converts fuel into vaporized gas in the combustion tube 4 with both ends open, and further includes a fuel spray body 16 in the vaporizer tube 7 that is rotated by a fan motor 28 and spouts out fuel. A combustion discharge port 12 is formed in one opening of the vaporization tube 7 and a fuel release plate 11 is attached thereto, and the other opening of the vaporization tube 7 is communicated with the main combustion chamber 20.
A ring-shaped preheating burner 2 that extends downward from a rectification chamber 24 that communicates with the upper part and has a plurality of small flame ports 26 that face each other at a constant interval on the outer periphery of the lower part of the vaporizing cylinder 7.
5, it is possible to perform gasification combustion automatically without installing an expensive heater, and it is also possible to preheat the vaporization cylinder efficiently and uniformly in a short time, so that the vaporization The vaporized gas formed by the heat of the cylinder is also stable and uniform, and gasification combustion with a short flame can be performed well with blue flame.
