Description

[Detailed description of the invention] This invention is a vaporization burner that automatically shifts the sent fuel from the main combustion state to the vaporization combustion state by means of a vaporization cylinder fixed in a non-rotating state within the combustion cylinder. This invention relates to a kerosene vaporizing burner that can prevent a vaporizing cylinder that generates combustion flames from becoming abnormally high temperature and being burnt out due to heating of combustion flames, and can perform vaporizing combustion favorably over a long period of time.

The vaporization cylinder is rotatably positioned in the combustion cylinder, and the fuel sent into the vaporization cylinder is diffused and transferred by the rotational centrifugal force of the vaporization cylinder and the forced air, and then transferred in fine particles into the combustion cylinder. The kerosene vaporizing burner was originally developed as a kerosene vaporizing burner, which not only scatters the fuel into the vaporizer and generates live combustion, but also quickly vaporizes and burns the fuel that diffuses and transfers in the vaporizing cylinder by the heating action of the live combustion flame as vaporized gas. It was developed by the applicant.

By the way, in the above-mentioned burner, the vaporization cylinder is forcibly rotated within the combustion cylinder, so during the continuation of vaporization combustion, the delivered fuel is diffused by the centrifugal force of the rotation of the vaporization cylinder and the forced air jet. Since the vaporizer is transferred downward while spreading all over the inner periphery of the vaporizer, no matter how much the vaporizer is heated by the combustion flame, the vaporizer will not come into contact with the forced air and the supplied fuel and become abnormally heated, and the vaporized gas will continue to flow. However, when the vaporizer cylinder is fixed in the combustion cylinder in a non-rotating state, not only forced air but also the atomized fuel flows down evenly over the inner circumference of the vaporizer cylinder. Inevitably, the flow is biased to one side, and there are parts where the vaporizer cylinder does not come into contact with the forced air and the atomized fuel, and as a result, combustion heat is concentrated in the vaporizer cylinder where there is no contact, resulting in an abnormally high temperature. The carburetor cylinder is quickly burnt out or damaged, and has a major drawback in that good vaporization combustion cannot be carried out over a long period of time.Even if fuel is sprayed into an abnormally heated carburetor cylinder, the sprayed fuel Because of its abnormally high temperature, it forms beads and quickly flows down, and does not turn into vaporized gas.Therefore, it is not possible to expect stable combustion, but it also has the disadvantage that it cannot continue vaporized combustion in a completely blue flame state.
This is something that is strongly desired to be resolved.

In view of the above, the present invention is a vaporizing burner of the type in which the vaporizing cylinder is disposed in the combustion cylinder in a non-rotating state and the fed fuel is automatically transferred from the raw combustion state to the vaporized combustion state.
Numerous heat dissipating fins are implanted radially around the inner circumference of the vaporizer cylinder,
The sprayed fuel flowing down along the inner surface of the vaporization cylinder and the flowing forced air are brought into contact with the heat radiation fins, and the heat applied to the vaporization cylinder is absorbed through the heat radiation fins, thereby preventing the vaporization cylinder from being heated to an abnormally high temperature state. Perhaps because of its active prevention, kerosene is able to quickly generate vaporized gas without forming beads due to the heat of vaporization from its heat-dissipating fins, allowing vaporized combustion in a complete blue flame state to continue for a long period of time. The present invention is intended to provide a vaporizing burner, and the configuration of the device according to the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a combustion tube made of a material such as a thin iron plate, with a gas chamber 3 having a hollow shape on two inner sides excluding the flame nozzle 2, and an inner bottom wall 4 in the center of the gas chamber 3. An open portion 5 is provided by bulging inward, and a combustion disk 6 is mounted on the inner circumferential surface of the gas chamber 3 for performing fume combustion of vaporized gas.

A cooling chamber 8 is provided above the inner bottom wall 4 by extending wall plates 7 at intervals, and this cooling chamber 8 is inserted into the center of the open portion 5 of the gas chamber 3 to form a blower tube. A part of the forced air flowing through the cooling chamber 9 is blown into the cooling chamber 8.

Inside the combustion cylinder 1 at a position opposite to the open part 5, there is an inner U, and a carburetor cylinder 11 with one side open, which is covered with a flow prevention body 12 such as a wire mesh, is immobilized by a support rod 13. Fix it and position it like this.

Reference numeral 14 denotes a spray body inserted into the blower tube 9, and a nozzle 15 for spraying the fuel into the vaporization tube 11 is provided at the tip.

Reference numeral 16 denotes a fuel scattering plate which is located between the cooling chamber 8 and the vaporization cylinder 11 and is suspended so that it can freely rotate by the blowing action of forced air flowing in the blower cylinder 9 with the spray pipe 14 as an axis. This is made by cutting and raising a single board from the inside by spray processing or the like so as to form an inclined blade 17, a moisture gas passage 18, and a scattering surface 19. The mixed gas passage 18 is opened to the outside of the blower tube 9, and the scattering surface 19 is located at the open end of the vaporizer tube 1.
1 is positioned so that a slight scattering gap is formed at the open end thereof.

Note that a ventilation hole is formed after the inclined steel plate 17 is cut and raised.

Reference numeral 20 represents a blowhole provided at the upper part of the cooling chamber 8, and reference numeral 21 represents a spark plug.

Reference numeral 22 denotes a large number of heat dissipation fins attached radially to the inner circumferential surface of the vaporizing cylinder 11.

Next, the operation of the present invention will be explained.

When a forced air is caused to flow into the blast tube 9 at a signal, the forced air hits the inclined blade 17 and causes the fuel scattering plate 16 to rotate at high speed around the spray pipe 14, while a portion of the forced air passes through the ventilation opening. After being injected into the vaporizing tube 11 which is provided in a non-rotating state and being introduced into the gas chamber 3, the forced air flows from the combustion plate 6 to the combustion tube 1, and furthermore, a part of the forced air flows through the scattering gap to the combustion tube 1.
The remaining air is injected into the cooling chamber 8 through the ventilation tube 10 and stored therein, and then all the air is injected into the combustion tube 1 from the blowhole 20 all at once.

In such a state, the fuel is diffused into a thin film due to the forced air blowing and diffusion effect and the flow prevention and diffusion effect of the flow prevention body 12, while moving to the open side and rotating from the end. The fuel drops onto the scattering surface 19 provided on the fuel scattering plate 16, becomes fine particles from the scattering gap due to the centrifugal force and a part of the ejected forced air, and is scattered into the combustion tube 1, where it is ignited to cause raw combustion.

During this main combustion, a portion of the cold air introduced into the cooling chamber 8 from the jet nozzle 20 is injected, so that the raw combustion becomes even better.

Since the vaporization tube 11 is intensely heated by the occurrence of raw combustion, the fuel sprayed from the nozzle 15 into the vaporization tube 11 quickly becomes vaporized gas due to the heating effect during the above-mentioned diffusion transfer, and this vaporized gas is When passing through the mixed gas passage 18, it is stirred and mixed with the forced air, becomes completely warm gas, is press-injected into the gas chamber 3, and is combusted in a jet under a constant pressure state.

By the way, during the continuation of the vaporization combustion as described above, the vaporization cylinder 11
is fixed in the combustion tube 1 in a non-rotating state, so the forced air and sprayed fuel injected into the vaporization tube 11 do not necessarily flow down evenly along the inner surface of the vaporization tube 11.
1. There are parts of the inner circumferential surface that are not directly contacted by the forced wind or the atomized fuel, so the uncontacted parts of the vaporizer cylinder 11 become abnormally high in temperature due to the heating effect, and when they are used as equipment, they are burnt out. It will end up being put away.

However, in the device of the present invention, a large number of heat dissipating fins 22 are installed radially on the inner periphery of the vaporizing tube 11, so that the heat applied to the vaporizing tube 11 is transferred to the heat dissipating fins. 22, the heat dissipation fins 22, the forced wind and the sprayed fuel come into direct contact and remove the heat of vaporization, reliably preventing the vaporization tube 11 from becoming abnormally high temperature, and preventing the sprayed fuel from becoming beads and quickly vaporizing the fuel. It is press-fitted into the gas chamber 3 as a gas chamber.

Therefore, even if the vaporization combustion state is continued for a long period of time, stable vaporization combustion can be carried out without causing burnout of the vaporization cylinder.

In short, the present invention has the above-mentioned configuration, so that when the vaporizer tube 11 that diffuses and transfers the sprayed fuel or evaporates the sprayed fuel is fixed in the combustion tube 1 in a non-rotatable state, However, the rotating fuel scattering plate 16 can precisely form the sprayed fuel into fine particles and scatter it into the combustion tube 1, resulting in quick live combustion. The atomized fuel is quickly evaporated by the heat of vaporization from the vaporization cylinder 11, which has been heated to a high temperature by the heating effect, and the generated vaporized gas is stirred and mixed with the hot air whose temperature has been raised by the heating effect to form a complete mixed gas. The direction from the chamber 3 to the vaporization cylinder 11 causes jet combustion, and the combustion can automatically shift from the main combustion state to the vaporization combustion state. Even if the vaporization tube 11 is heated to an abnormal temperature due to the flow not flowing down evenly along the surface, the heat dissipation fins 22, which are attached in large numbers radially around the inner periphery of the vaporization tube 11, disperse the sprayed fuel and forced air. By directly contacting the vaporizing tube 11, the heat of vaporization applied to the vaporizing tube 11 is absorbed through the heat dissipating fins 22, thereby preventing a burnout accident due to an abnormally high temperature of the vaporizing tube 11, and at the same time quickly preventing the sprayed fuel from becoming beads. This has the effect of generating vaporized gas and producing a stable blue flame over a long period of time.

The device of the present invention can also have the same effect on the kerosene vaporizing burner of the second embodiment as shown in FIG.

In this embodiment, there is a cup-shaped scattering body 23 in the center of the above-mentioned fuel scattering plate 16 for spraying and scattering the sent fuel onto the inner surface of the vaporizing cylinder 11, and a cup-shaped scattering body 23 for generating forced air around the outer periphery of the cup-shaped scattering body 23. The wind blowing blades 24 are provided in a single straight shape so that they are both located within the inner diameter of the blow tube 9, and further outside the wind blowing blades 24 are a mixed gas passage 18 and a scattering surface 19. are integrally molded.

The above-mentioned scattering plate 16 is directly connected to the rotating shaft 25 inserted into the blower tube 9 and is forcibly rotated.
4 is blown into the vaporization cylinder 11 to simplify the configuration, and a cooling fumarole chamber 26 is provided in an annular shape around the opening 5 of the gas chamber 3 to blow the cold air into the vaporization cylinder 11. A curtain is formed on the inner bottom wall 4 to prevent burnout of this part.

27 is an oil pipe.
