公報に記載されていて公知である。Conventional technology Conventionally, kerosene and other liquid fuels are evaporated from an initial raw combustion state, and the generated vaporized gas is stirred and mixed with combustion air to form a complete mixed gas, and the vaporized combustion flame is ejected from the tip side. In order to emit flame, there is a combustion cylinder equipped with a gas chamber.
A vaporizer cylinder with a closed tip, an open base end, and a fuel oil diffuser attached to the inner surface of the tip side is rotatably arranged, and inside the vaporizer cylinder there is a gas cylinder from the bottom wall side of the combustion tube to the tip side of the blower tube. A vaporizing burner facing the above is well known, having been described in, for example, Japanese Patent Application Laid-open No. 188911/1983 before the present application.

たものである。Problems to be Solved by the Invention By the way, in the above-mentioned known vaporizing burner, combustion air is blown into the vaporizing cylinder through the blower cylinder, and is stirred and mixed with the evaporated vaporized gas to generate air-fuel mixture. As a means of obtaining air flow, a blower tube whose tip opening is not constricted in any way, or a blower tube whose tip opening is slightly tapered and smaller is usually used.

り能率的に達成できない問題が生じた。However, when the combustion air is blown into the vaporization cylinder using the above-mentioned blower, the blowing pressure is weak, so the area of the blown combustion air is larger than the opening at the tip of the blower. At the moment when the combustion air is blown into the vaporization cylinder, the blowing pressure is further reduced, and most of the combustion air is not blown toward the top side of the inner surface of the vaporization cylinder, but is immediately diffused into the vaporization cylinder from the tip opening end. After that, a phenomenon occurs in which the combustion air is reversely circulated along the outer circumferential surface of the blower tube, and as a result, under the influence of the reversed eddy air flow generated by the reversed circulation of the combustion air, a fuel supply pipe is formed on the surface of the fuel diffuser. A part of the fuel that was being supplied from the opening at the tip of the fuel tank is forcibly attracted and scattered, hits the oil pipe and flows down, or is directly introduced into the gas chamber without hitting the inner surface of the vaporizer cylinder. Furthermore, it causes harmful effects such as part of the fuel supplied to the surface of the fuel diffuser being sprayed around, making it impossible to supply a predetermined amount of fuel toward the inner surface of the top of the vaporization cylinder, which results in stable vaporization. A problem arose in that combustion could not be achieved efficiently over a long period of time.

たものである。Therefore, the present invention opens a constricted air outlet in which the combustion air is actively concentrated and blown toward the inner surface of the top of the vaporizer cylinder along the surface of the fuel diffuser by means of a narrow wall provided at the tip side of the blower tube. A predetermined amount of combustion air can be easily obtained no matter how small the diameter of the narrowed air outlet is by opening a large number of auxiliary air outlets in the narrow wall around the narrowed air outlet. Furthermore, a fuel supply pipe with its tip facing the surface of the fuel oil diffuser is passed through with an air flow passage formed in one of the many auxiliary ventilation ports.
Even if a part of the fuel flows down the outer circumferential surface of the fuel supply pipe during refueling work, the blowing up action of the combustion air jetting out from the air flow passage will prevent any further flow of the fuel from flowing down. This prevents the falling fuel from flowing out of the burner, and allows the supplied fuel to be diffused and transferred over the surface of the fuel diffuser toward the inner surface of the top of the vaporizer cylinder by the intensively blown combustion air. The above problem has been solved by providing a vaporizing burner that can continue stable vaporizing combustion over a long period of time.

The gas is sent to the gas chamber 10 through the blast tube 19 and the vaporization tube 11, and finally the gas chamber 10 is also ejected upward. If fuel is supplied onto the surface of the fuel diffuser 25 under such conditions, the fuel will not be forcibly concentrated through the narrow air outlet 2G opened at the tip side of the blower tube 19, and the fuel will not be forced into the fuel diffuser. 25 surface toward the top inner surface of the vaporizer tube 11 and the rotational action of the fuel oil diffuser 25, the combustion air is diffused and transferred in the form of fine particles, and the fuel is supplied to the top inner surface of the vaporizer tube 11. Then, after being diffused and transferred with the inner surface of the vaporizing tube 11 facing the open side, it is ejected toward the inner periphery of the combustion tube 1, whereupon it is ignited and quickly burnt live.

継続させることができる。When the fuel flows into the combustion tube 1 and is burnt raw in this way, the entire vaporization tube 11 is heated by the raw combustion flame, and the inside temperature is quickly raised to the atmospheric temperature at which vaporization occurs. ,
The fuel supplied to the inner surface of the top of the vaporization tube 11 via the fuel diffuser 25 quickly evaporates and vaporizes while being diffused and transferred toward the base end open side along the inner surface of the vaporization tube 11. The gas is well stirred and mixed with the circulating heated combustion air to form a complete mixed gas, which is then pressurized into the gas chamber 10, and is then blown into the gas chamber under constant pressure to turn the vaporized combustion flame into a field. I can do it. Therefore, according to the invention described in item 1,
The heated combustion air vigorously blown out from the narrow air outlet 20 is blown out in a concentrated manner toward the inner surface of the top of the vaporizer cylinder 11 along the surface of the fuel diffuser 25 without any reduction in blowing pressure. This eliminates the scattering of fuel around the surroundings, which is caused by the combustion air flowing into the vaporization cylinder 11 and flowing in a reversed vortex state due to a decrease in blowing pressure in conventional vaporization burners, and always maintains a predetermined amount of fuel. By supplying fuel to the inner surface of the top of the vaporization cylinder 11, good vaporization combustion can be stably continued over a long period of time.

If the fuel supply pipe 26 facing the surface of the fuel oil diffuser 25 is penetrated so that an air passage 30 is formed between the auxiliary ventilation port 29 and the fuel supply pipe 26, a part of the fuel will be absorbed during the refueling operation. Even if a situation occurs in which the fuel flows down along the outer circumferential surface of the pipe 26 and flows out of the burner, the flowing fuel is transferred to the air flow path 30.
The heated combustion air blows out more forcefully and is forced up, preventing the fuel from flowing down and preventing fires from occurring.

This shows an example of a vaporizing burner that can prevent the flowing fuel from flowing into the burner even if a situation where the fuel oil flows out of the burner occurs. If so, the tip side of the fuel supply pipe 26 is passed through one of the auxiliary ventilation ports 29 opened in the narrow wall 21, and then the tip opening 2T is inserted into the fuel diffuser 25. The oil supply pipe 2 is exposed to the surface and penetrates through the auxiliary air outlet 29.
6, an air flow passage 30 is formed between the air flow passage 30 and the air flow passage 30.
A part of the heated combustion air is vigorously blown up to blow up the fuel flowing down along the outer circumferential surface of the fuel supply pipe 26 to prevent it from flowing down, thereby preventing the flowing fuel from accidentally flowing out of the burner. This eliminates the risk of fire and enables stable, fire-free combustion to continue for a long period of time.

を継続させることができる効果を奏する。Effects of the Invention In short, the present invention has the above-mentioned technical means, so that the fuel supplied to the surface of the fuel oil diffuser 25 through the fuel supply pipe 26 is supplied into the vaporization tube 11, and the nuclear fuel is blown into the combustion tube 1.・The heating effect of the live combustion flame evaporates and vaporizes the fuel supplied into the vaporization cylinder 11 to form a complete mixed gas, and the vaporization combustion flame is directed upward from the gas chamber 10. Even in the case of a vaporizing burner that uses field soil, a narrow air outlet 2G narrowed by a narrow wall 21 is opened on the tip side of the blower tube 19, and the combustion air that is vigorously blown out from the narrow air outlet 2G is used to transfer fuel to the fuel. It is possible to actively guide the gas toward the inner surface of the top of the vaporizer cylinder 11 while following the surface of the diffuser 25, and as a result,
During fuel refueling work, the fuel is reliably prevented from being sprayed into the vaporizer cylinder 11 by the reverse eddy air flow, and the vaporizer cylinder 11 is always maintained.
Is it possible to accurately supply fuel to the inner surface of the top, quickly convert all the fuel into mixed gas, and then combust it from the gas chamber 10? Even in the case where the openings are made on the tip side of the FP9, there are many auxiliary ventilation openings 29 opened in the narrowing wall 21 around the narrowing ventilation opening 20. By blowing air toward the inner surface of the top of the cylinder 11, it is possible to prevent a shortage of combustion air and easily maintain good vaporization combustion. One was used to penetrate the oil supply pipe 26, and the tip opening 2T was exposed to the surface of the fuel diffuser 25, and an air flow passage 30 was provided between the auxiliary ventilation port 29 and the oil supply pipe 26, so that the refueling operation was easy. Even if a part of the fuel flows through the outer peripheral surface of the fuel supply pipe 26 and flows out of the burner for some reason, the flowing fuel is transferred to the air flow passage 30.
This has the effect of preventing the combustion air from flowing downward by blowing up the combustion air, preventing an accident from flowing out of the burner, and allowing stable vaporization combustion to continue at all times.
