とができる気化バーナに関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for reducing the temperature between the fuel nozzle and the fuel diffuser surface even when the temperature near the fuel supply position to the hollow fuel diffuser surface becomes high due to continued vaporization combustion. By maintaining a preset air gap, a predetermined amount of fuel can be constantly and stably delivered to the hollow fuel oil diffuser, and at the same time, the air guide cylinder can be prevented from becoming distorted due to heat. Combustion air is blown into the vaporization cylinder from the ventilation passage along the ventilation guide tube and from the ventilation opening into the vaporization cylinder, forming a concentric circle with respect to the rotating shaft that directly connects the vaporization cylinder, and is evenly distributed under an even air distribution state. The present invention relates to a vaporizing burner that can easily generate more uniform vaporized gas and homogeneous mixed gas by blowing air to the burner, and can continue stable vaporizing combustion over a long period of time.

は給油管８の先端を臨ませたものである。Conventional technology Conventionally, a vaporizing burner that can vaporize and burn the fuel from a raw combustion state by diffusing and transferring the fuel supplied to the fuel diffuser through the fuel supply pipe toward the inner surface of the rotating vaporizing cylinder has not been fully developed. This is well known as described in, for example, Japanese Unexamined Patent Publication No. 57-188911 before the application, and this will be explained using FIG. 4. That is, the combustion tube 1 has an open tip and a closed base end.
A combustion plate 3 with a large number of gas ejection holes 4 perforated therein is disposed, a gas chamber 2 is provided between the combustion tube 1 and the combustion plate 3, and a gas chamber is provided in the central open part 5 of the gas chamber 2. A vaporizer cylinder 6 communicating with the evaporator 2 is rotatably disposed, and
The tip of a fuel supply pipe 8 faces the surface of a fuel diffuser 7 disposed inside the top of the vaporizer cylinder 6.

とができない問題が生じた。 However, when the fuel supply operation is carried out using a pipe-shaped fuel supply pipe as described above, when the vicinity of the fuel supply position, that is, the inside of the carburetor cylinder, becomes abnormally high temperature due to continued combustion, The fuel supply pipe itself may slightly kink due to temperature changes, and this kink phenomenon becomes particularly large as the vaporizing burner becomes smaller. The oil gap cannot be maintained,
As a result, it is not possible to achieve the desired vaporization combustion because a predetermined amount of fuel cannot be continuously and accurately delivered, and when starting combustion, in order to generate vaporized gas or mixed gas, The blower tube for blowing combustion air into the vaporizer cylinder from the air passage is usually made of thin material, so when the temperature inside the vaporizer tube becomes abnormally high as mentioned above, the blower tube The heat itself causes distortion and deformation, and the combustion air is no longer blown into the vaporization cylinder under an even air distribution state, and as a result, the fuel sent to the inside of the vaporization cylinder is unevenly blown. Due to the blowing action of the combustion air that is blown in a distributed state, it is diffused and transferred in a non-uniform state, and it goes without saying that it is not possible to evaporate and vaporize all the fuel in a uniform state. The agitation and mixing of the generated vaporized gas and the combustion air also became unstable, making it impossible to obtain a homogeneous mixed gas, resulting in the problem that stable vaporization combustion could not be continued for a long period of time.

せることができる。Operation Now, when starting the burner, if the carburetor cylinder 107 is rotated at high speed and combustion air is blown from the air passage 102 into the air guide cylinder 112 at the same time, a part of the combustion air will pass through the air passage 113. After air is blown into the hollow fuel diffuser 112, the vaporizer cylinder 10 is opened from the top side.
At the same time, other combustion air is blown directly into the vaporizer cylinder 107 from the air outlet 121 . The combustion air then passes through the vaporization tube 107 into the gas chamber 105 and is finally injected into the combustion tube 101 from the gas chamber 105. Therefore, if fuel is supplied into the oil supply passage 115 under the above conditions, the fuel will be transferred from the oil supply passage 115 to the rotating hollow fuel diffuser 11.
9 is supplied to the inner circumferential surface of the vaporizer tube 107, and after being diffused and transferred in a thin film on the inner circumferential surface by the blowing action of the combustion air blown from the ventilation port 113, the inner circumference of the vaporizer tube 107 is released from the top side together with the combustion air. It is sprayed towards the surface. The fuel sprayed toward the inner circumferential surface of the vaporization tube 107 as described above is formed into a thin film by the rotational centrifugal action of the vaporization tube 107 and the blowing action of the combustion air directly blown from the air outlet 121. After being diffused and transferred, it is sprayed in the form of fine particles from the open end of the vaporization tube 107 toward the inner circumferential surface of the combustion tube 101, and is ignited to be burned live. When a live combustion flame is generated in the combustion tube 101 in this way, the vaporization tube 107 is quickly heated, so that the hollow fuel diffuser 11
9 The fuel supplied to the inner circumferential surface of the hollow fuel diffuser 11
The vaporized gas is evaporated and vaporized while being diffused and transferred along the inner circumferential surfaces of the vaporizer cylinder 107 and the vaporizer cylinder 107, and the generated vaporized gas is stirred and mixed with the circulating combustion air, becomes a complete mixed gas, and is pressurized into the gas chamber 105. The gas is then injected all at once from the gas chamber 105 under an equal pressure condition, and is vaporized and combusted by ignition. By the way, as mentioned above, even if the vicinity of the fuel supply position, that is, the inside of the vaporization cylinder 107 becomes abnormally high temperature due to the continuation of vaporization combustion,
Since the oil supply passage 115 for supplying fuel is provided integrally within the thick-walled ventilation guide cylinder 112, the oil supply passage 115 itself does not twist due to changes in the atmospheric temperature inside the vaporization cylinder 107. Since the position is maintained, the oil feeding gap formed between the tip opening end of the oil supply passage 115 and the surface of the hollow fuel oil diffuser 119 is always maintained constant.
A predetermined amount of fuel can be continuously supplied to the surface of the hollow fuel diffuser 119 to stably continue vaporization and combustion of a predetermined amount, and at the same time, the air blowing guide tube 112
Since the wall is thick enough not to be unnecessarily deformed due to thermal changes, the air guide tube 112
The combustion air blown into the interior is distributed through the hollow fuel diffuser 119 through the ventilation opening 113 under an even distribution state.
Also, air is blown into the carburetor tube 107 from the air outlet 121, and the supplied fuel is uniformly diffused and transferred by combustion air with an even distribution of air, and quickly spreads over the entire inner circumference of the carburetor tube 107. At the same time, the vaporized gas generated is stirred and mixed with evenly distributed combustion air to obtain a homogeneous mixed gas, which allows stable vaporization and combustion to continue over a long period of time. .
