本発明は家庭用の暖房等に用いられる燃焼装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a combustion device used for home heating and the like.
従来の技術
従来、この種の燃焼装置としては石油ストーブ等に用い
られている吸い上げ気化方式の燃焼装置があるが、これ

熱を得ていた。BACKGROUND ART Conventionally, as a combustion device of this type, there is a suction vaporization type combustion device used in oil stoves, etc., but this has an inner flame tube 6 having a large number of air holes 11 as shown in FIG. The tip of the wick 1 is exposed in the combustion chamber 8 formed between the outer flame tube 7 and the outer flame tube 7, and the combustion is vaporized and combusted. Normally, the outer flame cylinder 7 forms a red-hot part 16 having a through hole 17 with a large opening area above the constriction part 15 of the outer cylinder 9, and the lamp wick 1
The fuel vaporized from the fuel and the air introduced into the combustion chamber 8 through the through holes 17 were mixed and combusted, causing the red-hot section 16 to become red-hot, thereby obtaining radiant heat.
発明が解決しようとする問題点
しかし、上記の様な構成では、次のような問題を生じて
いた。Problems to be Solved by the Invention However, the above configuration has caused the following problems.

がると多量のＣＯが発生する様な状態になっていた。以
上の現象は、燃焼筒内の排ガス測定を行った結果、内炎
筒６内部の流れに主原因があることが明らかになった。In normal strong combustion, as shown in Fig. 6, a secondary flame f1 is formed above the inner flame tube 6 and the outer flame tube 7, and the unburned components that have risen in the combustion chamber 8 are completely combusted, which is good. It shows excellent exhaust gas characteristics. However, when the exposed height of the lamp wick 1 is lowered to reduce the amount of combustion, the flame descends into the combustion chamber 8 and is formed as shown at f2. In this case, the flame f3 that was formed in the air hole 11 and the through hole 17 of the inner flame cylinder 6 is no longer formed above the flame f2. Conventionally, under such conditions, exhaust gas characteristics, particularly Co and /GO2, have deteriorated rapidly. In addition, if the combustion device is used for a long time in a well-sealed room (oxygen deficient condition), the amount of combustion will gradually decrease as the oxygen concentration decreases, but as mentioned above, if the flame descends into combustion chamber B, The situation was such that a large amount of CO was being generated. As a result of measuring the exhaust gas inside the combustion cylinder, it became clear that the main cause of the above phenomenon was the flow inside the inner flame cylinder 6.

良い部屋で長時間燃焼させ、酸素濃度が減少した場合（
酸欠状態）でも同様である。That is, the CO concentration at the line A-A' in FIG. 6 was more than 11,000 pp near the upper end during weak combustion (the flame descending into the combustion chamber 8 at f2). From this, it is clear that CO is diffusing from the combustion chamber 8 into the inner flame tube 6 inside the inner flame tube 6 as indicated by the broken line a, and the mixed gas containing this high concentration of CO is CO is directly released into the atmosphere from the air hole 11 above the flame f2.
/co2 characteristics deteriorate rapidly. This phenomenon occurs when combustion is performed for a long time in a well-sealed room and the oxygen concentration decreases (
The same is true for oxygen-deficient conditions.

This is provided with a flow control tube 25 that extends upward from near a position facing the lamp wick 1 inside the inner flame tube 6 and has a bottom surface in a space formed between the inner flame tube 6 and the inner flame tube 6.

上問題があった。This configuration realizes ■Separation of airflow and diffused unburned gas ■Prevention of diffusion to the inside of the inner flame cylinder ■Re-burning of unburned gas by air supplied from the upper part of the restriction cylinder, thereby reducing the deterioration of Co/C O2 It is prevented. With this configuration, it was possible to significantly improve Co/c O2, but with this configuration, the flow restrictor tube 25 has a bottom surface, so the supply of air to the inner flame tube 6 is restricted. Therefore, the amount of air on the air passage 20 side increases, the air balance in the combustion chamber 8 is disrupted, and yellow flame may occur in the combustion chamber B, which poses a problem in terms of appearance.

The aim is to obtain a large and safe combustion device.

する。したがって制流域２２には未燃ガスが充満する。In the above configuration, when the lamp wick 1 is ignited, combustion starts, and high-temperature combustion gas due to combustion rises in the combustion chamber 8, creating a thermal draft, and the air necessary for combustion is transferred to the inner flame tube 6 and the outer flame tube 7. The fuel is supplied into the combustion chamber B through the hole 11 and the through hole 17 of the red-hot section 16, and combustion continues. The flow of combustion gas and air inside the inner flame tube 6 and the combustion chamber 8 at this time will be explained with reference to FIG. 2. Air supplied from inside the inner flame cylinder 6 is divided into two parts: white arrow -, which is supplied from below the inner cylinder 21 to the vicinity of the lamp wick 1, and white arrow (white arrow), which ascends through the air introduction path 24. A part of the rising air passes through the control area 22 as indicated by the white arrow C and is supplied to the combustion chamber 8. Further, the air supplied to the inner flame cylinder s-h is supplied to the combustion chamber 8 and above from the air hole 11 and the vent hole 13 as indicated by the white arrow d. On the other hand, the fuel vaporized by the air flow becomes a mixed gas with air and rises in the combustion chamber 8 mainly as shown by the black arrow e. However, a part of the mixed gas diffuses into the control area 22 as shown by the black arrow f. Therefore, the control area 22 is filled with unburned gas.

、排ガス特性（ｃｏ／ｃｏ２）はあまり悪化しない。This unburned gas is suppressed from diffusing inside the inner cylinder 21 in the airflow portion 23 by the air flow arrow d, and is again supplied to the combustion chamber 8 as shown by the black arrow 9. Therefore, during strong twist firing, unburned gas and air are supplied from near the end of the inner flame tube 6-H to the end of the combustion chamber 8 in a well-mixed state, so the combustion efficiency is increased by 5 in the vicinity of area A, and further combustion is performed here. The remaining unburned gas is combusted by the flame f formed above. Next, when the exposed height of the lamp wick 1 is lowered to reduce the amount of combustion, the flame gradually descends into the combustion chamber 8 and becomes a flame f3. The flow in this case is the same as that during strong twist firing, but since the amount of vaporized gas is significantly reduced, the amount of unburned gas flowing into the control area 22 is also reduced. Therefore, the mixing area with the air flow mountain arrow d moves downward, and the vicinity of area B becomes a good mixing area,
A flame holding state is formed in this part, the wall surface of the inner flame cylinder 6 is made red hot, and combustion is completed with the flame f formed above. In this case, most of the unburned gas that has flowed into the control area 22 is supplied into the combustion chamber 8 by the air flow mountain arrow d and is combusted by the flame f3.
In No. 4, there is almost no unburned gas component, and the air discharged from the flame f and the air holes 11 and 13 above is clean, and the exhaust gas characteristics (co/co2) do not deteriorate much.

燃焼室Ｂ内への黄火の発生もない。Above, we have described the case where the exposed height of the wick 1 is lowered to reduce the amount of combustion during normal combustion, but the same problem can occur when burning for a long time in a well-sealed room (oxygen deficient condition). Effects can be obtained. In other words, under oxygen-deficient conditions, the amount of combustion decreases as the oxygen concentration decreases, and a phenomenon similar to that observed when the exposed height of the wick 1 is lowered to reduce the amount of combustion is observed. The characteristics also become better. Furthermore, in this embodiment, since air is supplied into the control area 22 from the lower end of the inner cylinder 21, the air balance within the combustion chamber 8 is not disrupted and no yellow flame is generated within the combustion chamber B.

FIG. 4 shows the results of measuring the o/GO2 characteristics and the oxygen deficiency characteristics. The oxygen deficiency characteristics were measured at an initial combustion rate of approximately 1250 and 6 al/hr.
本実施例はＣｏ／ｃ Ｏ２特性、酸欠特性とも大幅に改
良されており、本発明の効果が明確である。In this example, both the Co/c O2 characteristics and the oxygen deficiency characteristics were significantly improved, and the effects of the present invention are clear.

同様に悪化する。Figures 3 and 4 show the results when the diameter of the inner cylinder 21 is 90% of the inner diameter of the inner flame cylinder, but since this effect changes depending on the diameter of the inner cylinder 21, in order to obtain the effect, Setting the diameter of the inner cylinder is extremely important. FIG. 5 shows the ratio (dlo) of the diameter d of the inner cylinder 21 to the inner diameter of the inner flame cylinder 6 and co/co.
2 (the maximum value of the CO/CO2 curve as shown in FIG. 3). The above effect is dl
It appears when o is 80% or more, but when it is 8096 or less, there is almost no difference from the case where no inner cylinder is provided, and the effect of the present invention is not manifested. This is considered to be caused by the flow and resistance in the control area 22. That is, when dlo is 80% or more and the control area is narrow, the control area 2 is moved by the white arrow C shown in FIG.
In addition to the flow velocity increasing, the air supplied to the inner cylinder 21 increases from the lower end of the inner cylinder 21 to the inner cylinder 21 because the ventilation resistance within the control area 22 increases.
Diffusion of unburned gas inside is unlikely to occur. However, d/
When D becomes 80% or less and the control area 22 widens, the flow velocity indicated by the white arrow C decreases, and the ventilation resistance within the control area 22 also decreases, so that unburned gas flows from the lower end of the inner cylinder 21 to the inside of the inner cylinder 21. Gas diffusion becomes more likely to occur, and Go/GO2 deteriorates as in the conventional example.
したがって内筒２１の径は内炎筒の内径の８０％以上と
することが重要である。Therefore, it is important that the diameter of the inner cylinder 21 is 80% or more of the inner diameter of the inner flame cylinder.
発明の効果
以上のように、本発明の燃焼装置によれば、次の効果か
えられる。Effects of the Invention As described above, the combustion apparatus of the present invention provides the following effects.
■ 内炎筒内方に内筒を設けているため、内筒内側への
未燃ガスの拡散が抑制される。■ Since the inner cylinder is provided inside the inner flame cylinder, the diffusion of unburned gas inside the inner cylinder is suppressed.

通気孔から高濃度のＣＯが直接大気中に放出されること
はない。■ The flow of unburned gas leaking into the inner flame tube is blocked by the air supplied from the vent. Due to this shielding effect, the control area above the flame and the air introduction path contain almost no unburned gas, and high concentrations of CO are directly released into the atmosphere from the inner flame tube air vents and vents above the flame. It never happens.
■ 制流域内には拡散によって高濃度のＣＯを含む未燃
ガスぎ流入するが、通気部から供給される空気によって
燃焼室内に再導入されて燃焼される。(2) Unburned gas containing a high concentration of CO flows into the control area due to diffusion, but is reintroduced into the combustion chamber by air supplied from the vent and burned.
■ 制流筒下端から制流域に空気が供給されるので燃焼
室内の空気バランスか崩れることはなく燃焼室内での黄
火の発生もない。■ Since air is supplied to the control area from the lower end of the flow control tube, the air balance within the combustion chamber will not be disrupted and no yellow flame will occur within the combustion chamber.
以上の効果により弱燃焼時や酸欠状態での排ガス特性の
急激な悪化を防止することにより燃焼特性が良好で燃焼
