ていた。BACKGROUND OF THE INVENTION Conventionally, this type of combustion device has a lamp wick 1 exposed in a combustion chamber C formed between an inner flame tube 6 and an outer flame tube 7 having a large number of air holes 11, as shown in FIG. This vaporizes and burns the fuel. Normally, the outer flame cylinder 7 has a red-hot part 15 in which the opening surface of the air hole 16 is considerably enlarged above the constricted part 14 of the outer cylinder 9, and a large amount of air flows from this air hole 16 into the primary combustion chamber 8. Air was introduced, mixed with the fuel vaporized from the lamp wick 1, and burned, making the red-hot part 15 red-hot and 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様な種々の問題を生じ
ていた。Problems to be Solved by the Invention However, the above configuration has caused various problems as described below.
(1)通常の燃焼では内炎筒6と外炎筒7の上端間で二
次炎f1を形成するが、過大燃焼をさせた場合は、二次
炎11は空気不足となるために黄火が生じ、極端な場合
にはスヌを多量に発生することがあった。(1) In normal combustion, a secondary flame f1 is formed between the upper ends of the inner flame tube 6 and the outer flame tube 7, but if excessive combustion occurs, the secondary flame 11 becomes yellow due to lack of air. In extreme cases, a large amount of sunu may occur.
(2)灯芯1の露出高さを低くして発熱量を小さくした

排出量が急激に増加する。また、赤熱部と端付近の赤熱
輝度も低下して外観上も不具合であった。(2) When the exposed height of the lamp wick 1 is lowered to reduce the amount of heat generated, the flame descends into the primary combustion chamber 8 and is formed as shown at f2. In this case, the air holes 11.1 of the inner and outer flame tubes 6.7
The flame f3 that was formed at 5 is no longer formed above the flame f2, and a large amount of air is guided in the direction of arrow a because the ventilation resistance is reduced. Therefore, the tip of the flame f2 and the vicinity of the contact point between the inner and outer flame tube 6.7 and the flame f2 are cooled, so the combustion reaction is suppressed here, and the combustion exhaust gas is released without the combustion reaction being completed. Carbon oxide emissions will increase rapidly. In addition, the red glow brightness at the red hot part and near the edges was also reduced, which was a problem in terms of appearance.

プリング18と一体で形成している。In FIG. 1, reference numeral 1 denotes a cylindrical lamp wick, which is set between an inner wick tube 2 and an outer wick tube 3 so as to be freely movable downward. The ends of the inner core tube 2 and the outer core tube 3 form an inner flame tray 4 and an outer flame tray 5, respectively, and an inner flame tube 6 and an outer flame tube 7 are placed thereon. During combustion, the two ends of the wick 1 are exposed in a combustion chamber 8 formed between an inner flame tube 6 and an outer flame tube 7, where the fuel is vaporized. Reference numeral 9 denotes an outer cylinder, and the inner flame cylinder 6, outer flame cylinder 7, and outer cylinder 9 are arranged in a substantially concentric circle in order from the inside, and are integrated and fixed by two clonupins 1o. Reference numeral 11 indicates a large number of air holes provided in the inner flame tube 6 and the outer flame tube 7. Reference numeral 12 denotes a secondary flame port formed in the inner flame tube 6 at the upper end of the primary combustion chamber 8, and the vertical and horizontal air hole intervals are smaller than those of other inner flame tube air holes.
It also has large diameter and densely packed air holes. Also, this secondary flame opening is set so that the air holes at the top and bottom have a large diameter. In this embodiment, the secondary flame port 12 is arranged vertically in four directions.
It is formed by a group of air holes in stages, and is divided into two stages, upper and lower, with the lower two stages having a larger diameter, but it is also possible to divide it into certain areas like this and change the diameter, or to gradually decrease the diameter from the bottom. It may also be used as a configuration. Reference numeral 13 denotes an inner flame tube top plate that closes the upper end opening of the inner flame tube 6. The outer flame tube 7 on the side from the throttle part 14 of the outer tube 9

る。In the above configuration, when the lamp wick 1 is ignited, combustion starts,
High-temperature combustion gas from combustion rises in the primary combustion chamber 8, creating a thermal draft, and the air necessary for combustion flows through the air holes 11 of the inner flame tube 6, the outer flame tube 7, and the through holes 16 of the red-hot part 15.
The fuel is then supplied into the secondary combustion chamber 8 and combustion continues. Second
As shown in the figure, a flame F is generated between the flame holding part 21 and the secondary flame opening part 12.
is formed. In this case, the air holes in the secondary flame port 12 have a larger diameter than the air holes 11 in the inner flame tube 6 and are densely packed together, so a large amount of air is supplied above the inner flame secondary combustion chamber 8. Flame Fr is less likely to run out of air, and even if it is over-combusted, little yellow flame is generated and no soot is generated. In addition, since the flame holding part 21 protrudes into the primary combustion chamber 8, the ventilation resistance in the secondary combustion chamber 8 increases, and the amount of air flowing into the primary combustion chamber 8 from the through holes 16 and air holes 11 is suppressed. It will be done.

火炎Fsが冷却されたシ、赤熱部15の上方が冷却され
ることはなく、燃焼排ガスの悪化を防ぐことができる。Therefore, the combustion amount in the secondary combustion chamber 8 can be reduced by 2, and even if the combustion amount is limited, the flame Fr is prevented from falling into the primary combustion chamber 8, so deterioration of combustion exhaust gas can be suppressed. . Furthermore, when the combustion amount is reduced as shown in Fig. 3, the flame becomes small like F8, but since the secondary flame port 12 is subdivided into dense air holes, the flame is spread through the upper air holes. The flame gradually disappears, but the flame remains below. In particular, in this embodiment, the secondary flame port 12 is divided and the air holes in the upper region 12a and lower region 12b are made larger, so that the flame in the upper region 12a becomes unstable as shown in FIG. Even if the flame is extinguished, the flame can be relatively stably maintained in the lower region 12b having a large pore diameter. In addition, flame holding part 2
Since a vortex is generated near the end of 1, it is effective in holding the flame firmly. Therefore, even when the combustion amount is reduced, while the flame Fs is cooled, the upper part of the red-hot part 15 is not cooled, and deterioration of the combustion exhaust gas can be prevented.
また赤熱体15を高温に保つことができるので、燃焼量
の広い調節幅にわたって良好な赤熱状態を保つことがで
き、大きな輻射を得ることができる。Furthermore, since the incandescent body 15 can be kept at a high temperature, a good incandescent state can be maintained over a wide adjustment range of combustion amount, and large radiation can be obtained.

る。In this embodiment, only the structure shown in FIG. 1 has been described, but other embodiments include one having a secondary combustion chamber 22 on the side of the primary combustion chamber 81 as shown in FIG. Similar effects can also be obtained with a structure having a secondary combustion chamber 22 and an upper incandescent body 23 within the secondary combustion chamber 22, as shown in FIG.
発明の効果
以北の様に本発明の燃焼装置によれば次の効果が得られ
る。In addition to the effects of the invention, the combustion apparatus of the present invention provides the following effects.
(1)二次炎口部を他の空気孔よりも径大とし、かつ縦
、横の空気孔間隔を小さく密集化しているため、−次燃
焼室と部へ多量の空気を供給することができるので過大
燃焼をさせても黄火、スヌの発生を抑制することができ
る。(1) The diameter of the secondary flame port is larger than that of other air holes, and the vertical and horizontal air hole spacing is small and dense, making it possible to supply a large amount of air to the secondary combustion chamber. Therefore, even if excessive combustion occurs, it is possible to suppress the occurrence of yellow fire and sunu.
(2)二次炎口部は細分割された密集空気孔であるため
、燃焼量を絞って火炎が小さくなり、二次炎口部の上方
領域の火炎が消滅した場合でも下方領域で火炎を保持し
、火炎の落ち込みを防止するので、燃焼排ガスの悪化を
防止することができる。(2) The secondary flame nozzle is a finely divided dense air hole, so the combustion amount is reduced and the flame becomes small, so even if the flame in the upper area of the secondary flame nozzle is extinguished, the flame in the lower area is still maintained. Since the flame is maintained and the flame is prevented from falling, deterioration of combustion exhaust gas can be prevented.
(3)保炎部の端部付近では渦流が形成され、火炎を強
固に保持するので、火炎の燃焼室内への落ち込みを防止
するのに更に効果がある。(3) A vortex is formed in the vicinity of the end of the flame stabilizing section to firmly hold the flame, which is more effective in preventing the flame from falling into the combustion chamber.
(4)保炎部は一次燃焼室内に突出しているため、燃焼
室内の通気抵抗が大きくなり、−次燃焼室内へ流入する
空気量が抑制されるので、−次燃焼室内での燃焼量を少
なくすることができ、したがって燃焼量を絞った場合で
も火炎が一次燃焼室内へ落ち込むのを防止することがで
きる。(4) Since the flame holding part protrudes into the primary combustion chamber, the ventilation resistance within the combustion chamber increases, and the amount of air flowing into the secondary combustion chamber is suppressed, reducing the amount of combustion in the secondary combustion chamber. Therefore, even when the combustion amount is reduced, it is possible to prevent the flame from falling into the primary combustion chamber.
