化燃焼させている。In a vaporizing burner, fuel oil such as kerosene is dispersed into fine particles in a vaporizing cylinder, evaporated and vaporized, and mixed with combustion air supplied as forced air to form a mixed gas that is vaporized and burned. The humid gas generated in the vaporization cylinder is first stored in the gas chamber, and then ejected from the start hole at a constant pressure to vaporize and burn.

発生を未然に防止せしめた。Therefore, when the amount of oil supply and air blowing are significantly reduced in order to reduce the amount of vaporized combustion using a vaporizing burner as described above, the moisture gas The amount of gas decreases extremely, and the false pressure from the false flame hole becomes unable to maintain the de-stable pressure.As a result, the gas mixture jetting speed and pressure from the flame hole decreases significantly, and this causes the gas chamber to deteriorate. There is a risk of flashback development, which could ignite.
Therefore, in order to solve this problem, the present applicant has provided an opening/closing body that opens or closes some of the numerous flame holes drilled in the combustion disk, so that it can be adjusted up and down in the gas chamber. Even when the amount of lacrimal gas generated is extremely small, the jet pressure in the gas chamber is maintained at a predetermined pressure to prevent backfire combustion from occurring.

じた。However, even with the above-mentioned configuration, if the combustion disk is bent due to the heating action during the continuation of vaporization combustion, and the closing action of the gas nozzle becomes inaccurate, "air mixture" may occur. A small portion of the gas leaked out from the closed false flame hole and was combusted, resulting in the drawback that accurate weight loss combustion could not be maintained.

添附図面に示された好適な実施例について説明する。In view of the above, the present invention divides a gas chamber into two chambers, a royal chamber and an auxiliary chamber, by a partition wall in which a gas passage is provided at an upper position, and the auxiliary chamber is connected to a lotus chamber through an air supply chamber adjacent to a combustion cylinder and an air supply hole. Through the opening and closing body, an opening and closing body which is adjusted to rise and fall while forming a small gap between it and the partition wall is housed in the sub-chamber. When the adjustment is made, a gas-blocking air curtain is generated that blows from the air gap toward the gas passage to reliably block the flow of muddy gas from the room into the auxiliary chamber, thereby reducing the amount of combustion only by the room. When adjusting the lowering of the opening/closing body, the air supply hole is closed and both main chambers are filled with mixed gas to achieve good increased combustion, thereby reducing the amount of mixed gas generated. The present invention is intended to provide a vaporizing burner that achieves more accurate combustion during combustion, and the configuration of the present invention will be described below with reference to preferred embodiments shown in the accompanying drawings.

方向に向け回転させる。In this state, fuel is supplied from the fuel supply pipe 13 to the fuel diffuser 12.
As shown in the figure, the fuel is atomized by the fuel diffuser 12 and transferred to the inner surface of the vaporization tube 8, and then transferred along the vaporization tube 8 due to the rotation of the vaporization tube 8 and the purging action of forced air. After being further dispersed into fine particles, the fuel is scattered into the combustion tube 1 through the fuel diffusion gap 16, and is ignited by the spark plug 21 to generate raw combustion. When raw combustion occurs in this way, the combustion heat rapidly heats the vaporizer tube 8 to a high temperature, so that the fuel that is subsequently scattered in the vaporizer tube 8 is evaporated and vaporized while flowing through the moisture passage 11. It is mixed with the combustion air blown from the blower tube 10 to become a humid gas, which is stored in the gas chamber 4 consisting of the rain chambers 4a and 4b. Then, the hawk gas stored in the gas chamber 4 is ejected into the combustion tube 1 at a constant pressure from a large number of flame holes 3, and as it is vaporized and burned by ignition, a part of the generated hawk gas is also vaporized. The gas enters the gas dilution chamber 18 and attempts to combust into the combustion tube 1 from the tip side. However, since combustion air is sent into the mixture gas lean chamber 18 via the vent pipe 20 from the start of vaporization combustion, the incoming moat gas mixes with this combustion air, resulting in a lean mixture. It becomes a gas and is ejected into the combustion tube 1 without being combusted, and is vaporized and burned only after being mixed with the previous vaporized combustion flame. Therefore, during the continuation of vaporization combustion, the base end side of the vaporization tube 8 is prevented from being burnt out and deformed, and this allows normal rotational operation to continue good vaporization combustion. It is possible to completely eliminate flammable combustion. By the way, when reducing the above-mentioned vaporization combustion amount for the purpose of use and performing a small amount of vaporization combustion, after reducing the amount of oil supplied from the oil supply pipe 13 and the amount of air blown from the air supply chamber 5, the sliding Zen 29 is Rotate clockwise in the state shown in Figure 2.

態を得るよう調整できる効果を奏する。Then, both the movable ring body 30 and the push-up swash plate 32 are rotated clockwise, and the push-up pin 27 mounted on the push-up swash plate 32 is raised. The body 26 rises horizontally to close the numerous flame holes 3 facing the chamber 4b, and then the opening/closing body 26 rises and moves to the operation of opening the flame holes 3. The closed air supply hole 24 is closed, and a part of the combustion air is forced into the subchamber 4b from the air supply chamber 5. As a result, the injected combustion air flows between the partition wall 22 and the opening/closing body 26. From the warm air gap 25 formed between them, fumes are emitted all at once toward the gas passage 23, and the gas passage 2
3 is forcibly shut off with an annular air curtain to reliably prevent moisture gas from entering the Liu room 4b from the royal room 4a. Therefore, when the amount of vaporized combustion decreases, it may be possible to accurately prevent eel gas from leaking and burning from the closed false flame hole 3, even if the combustion disk 2 bends during the continuation of vaporized combustion. Even if the closing action of the flame hole 3 by the opening/closing body 26 is inaccurate, it prevents leakage and combustion of the moat gas and at the same time prevents backfire combustion into the gas chamber 4, so that a good symptom is maintained. Quantitative vaporization combustion can be achieved. In short, since the present invention has the above-mentioned specific configuration, a small amount of flame generated when the opening/closing body 26 is ascended to close the false flame hole 3 facing one of the auxiliary chambers 4b forming the gas chamber 4. Is it possible to inject a small amount of concentrated gas only into Royal Room 4a and cause a small amount of vaporization combustion?
The opening/closing body 26 is lowered to connect the main and sub-chambers 4a and 4b to the gas passage 2.
3, it is possible to successfully achieve a large amount of vaporization combustion, and when a small amount of vaporization combustion is carried out, a part of the combustion air in the air supply chamber 5 can be Antechamber 4
b, and the combustion air is directed from the gas chamber 4 to the gas passage 23 through a small warm air gap 25 provided between the partition wall 22 and the opening/closing body 26 between the two main chambers 4a and 4b. An air curtain is formed to cut off the gas, and this air curtain is used to cut off the gas passage 23 to reliably prevent the mixed gas from flowing out from the royal chamber 4a to the auxiliary chamber 4b. This prevents part of the mixed gas from leaking out from the flame hole 3 and combusting, thereby eliminating the pressure drop of the moisture gas in the chamber 4a, and creating a stable small amount vaporization state without causing backfire combustion. It has the effect of being able to be adjusted to obtain.
