Detailed Description of the Invention [Industrial Field of Application] The present invention provides a system for maintaining the fuel nozzle and the fuel diffuser surface even when the temperature near the fuel supply position to the fuel diffuser surface becomes high due to continued vaporization combustion. The swirling combustion air is actively blown into the vaporizing cylinder to maintain a preset oil feeding interval between the two and to constantly send a predetermined amount of fuel to the fuel diffuser in a stable manner. The present invention relates to a vaporizing burner that can achieve highly stable vaporizing combustion by further promoting stirring and mixing of vaporized gas generated by combustion and combustion air.

However, when the fuel supply operation is performed using a pipe-shaped fuel supply pipe as described above,
Due to the continuation of combustion, the area near the fuel supply position,
When the inside of the carburetor cylinder becomes abnormally high temperature, the fuel supply pipe itself will be slightly twisted due to the temperature change. It may become impossible to maintain the preset oil supply distance between the fuel and the diffuser surface, and as a result, a predetermined amount of fuel cannot be continuously and accurately delivered, making it impossible to achieve the desired vaporization combustion. When starting combustion, the combustion air that is blown into the vaporization cylinder from the blower tube generally travels straight, so the vaporized gas that evaporates and vaporizes in the vaporization cylinder does not easily mix with the circulating combustion air. However, there were problems such as the inability to continuously obtain a homogeneous mixed gas, and as a result, stable vaporization and combustion could not be expected.

[Function] In the first invention shown in FIGS. 1 and 2, the carburetor cylinder 107 is now rotated at high speed and at the same time the combustion air is supplied from the air passage 102 to the blow guide cylinder 112.
When the combustion air is blown into the combustion chamber 101, the combustion air is blown into the vaporization tube 107 through the communication passage 113, and then passes through the vaporization tube 107 into the gas chamber 105, and finally, the combustion air is sent from the gas chamber 105 into the combustion tube 101. be done. Therefore, when fuel is supplied into the oil feed path 114 under the above conditions, the fuel is supplied from the fuel nozzle 116 to the surface of the rotating fuel oil diffuser 120, and then diffused along the surface of the fuel oil diffuser 120. while transferring to the inner surface of the top of the vaporizer cylinder 107, and furthermore, the vaporizer cylinder 1
07 After being diffused and transferred along the inner circumferential surface in a thin film form due to the rotational centrifugal action and the jetting action of combustion air, the combustion air is transferred from the open end of the vaporization pipe 107 to the combustion pipe 10.
1. It is sprayed in the form of fine particles toward the inner peripheral surface, and is ignited to cause live combustion. When a raw combustion flame is generated in the combustion tube 101 as described above, the vaporization tube 107 is quickly heated. During the diffusion and transfer, the vaporized gas is evaporated and vaporized, and the generated vaporized gas is stirred and mixed with the circulating combustion air, becomes a complete mixed gas, and is injected into the gas chamber 105 under equal pressure. Fumes are emitted all at once from 105, and the fuel 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 tube 107 reaches an abnormally high temperature due to the continuation of vaporization combustion, the oil feed path 114 for supplying fuel will not be able to reach the thick-walled ventilation guide tube 112. Since the fuel nozzle 116 and the fuel diffuser 120 are provided integrally within the vaporizer cylinder 107, the oil feed passage 114 itself does not twist due to changes in the atmospheric temperature inside the vaporizer cylinder 107, and its position is maintained. A predetermined amount of fuel is continuously supplied to the surface of the fuel diffuser 120 without causing any fluctuation in the refueling interval and always maintaining a preset refueling interval to vaporize a predetermined amount of fuel. Combustion can be continued stably.

In addition, in the vaporizing burner using the air guide tube 112 according to the second invention shown in FIGS. On the inner circumferential surface of the ventilation passage 113, swirling air passage grooves 121 for swirling and blowing combustion air in the same direction as the rotational direction of the carburetor cylinder 107 are carved at multiple intervals. The combustion air blown from the ventilation path 102 into the ventilation guide tube 112 flows through the ventilation path 113 and then flows along the swirling air path groove 121 to the vaporization tube 107.
The fuel nozzle 1
The fuel supplied from 16 to the surface of the fuel oil diffuser 120 and the fuel transferred along the inner surface of the vaporization tube 107 are diffused and transferred to become atomized while forming an even thinner film due to the jet action of the swirling wind. Therefore, the evaporation effect can be further promoted, and the generated vaporized gas is well stirred and mixed with the swirling wind, and a homogeneous mixed gas can be obtained at all times.As a result, compared to the vaporizing burner of the first invention, Thus, the vaporizing burner of the second invention is capable of continuing even more stable vaporizing combustion over a long period of time.

[Effects of the Invention] In short, the present invention provides a gas chamber 105 disposed within a combustion tube 101 connected to an air blowing passage 102, and a vaporization tube 107 communicating with the gas chamber 105 in a central open portion 106 of the gas chamber 105. Even if the vaporizing cylinder 107 is arranged rotatably, the ventilation passage 113 is opened on the distal end side of the inside of the vaporization cylinder 107, and the ventilation passage 113 is opened on the proximal side.
An air blowing guide tube 112 is provided which communicates with the air blowing tube 112, and an oil feed passage 114 is integrally provided inside the air blowing guide cylinder 112, and an oil feed passage 114 is provided inside the top of the vaporization cylinder 107 on the tip side of the oil feed passage 114. fuel oil diffuser 120,
Since the fuel nozzle 116 facing the surface of the fuel nozzle 120' is provided, the fuel is automatically transferred from a raw combustion state to a vaporization combustion state, so that if the vicinity of the combustion supply position, that is, the inside of the vaporization cylinder 107 becomes abnormally high temperature. Even in the case of
20 and 120' planes, and a predetermined amount of combustion is always carried out between the fuel diffuser 1
20 and 120', and as a result, there is no need to finely adjust the opening position of the tip of the oil supply pipe during the assembly process for mass production of vaporizing burners. Since it is formed with a slightly thick wall, it is difficult to generate a vortex of combustion air in the vicinity of the ventilation passage 113, and in addition, the combustion air passing along the ventilation passage 113 is blown directly along the outer peripheral surface of the fuel diffuser 120. It goes without saying that the fuel can be guided in the direction of the ventilation to ensure that it is diffused and transferred onto the surface of the fuel diffuser 120 in a thin film state. A vaporizer cylinder 107 is provided on the inner peripheral surface of the passage 113.
Since a plurality of swirling air passage grooves 121 for swirling and blowing combustion air in the same direction as the rotating direction of The air is forcibly turned into swirling air by the channel grooves 121 and blown into the vaporization cylinder 107, and is further stirred and mixed well with the vaporized gas generated in the vaporization cylinder 107, thereby continuously forming a homogeneous mixed gas. This has the effect of allowing stable vaporization combustion to continue over a long period of time.
