At the same time, it is an object of the present invention to provide a combustor that can stabilize combustion, perform complete combustion, and secure a sufficient amount of combustion over a long period of time.
灯芯気化式の液体燃料燃焼器は石油ストーブ、
石油コンロ等に従来より多く用いられているが、
これらには以下の様な種々の欠点があつた。 The wick vaporization type liquid fuel combustor is used in kerosene stoves,
It is more commonly used in oil stoves, etc., but
These had various drawbacks as described below.
点火時は点火ヒータ等により灯芯の一部もし

閉塞して、点火や火まわりが不可能となつた
り、あるいは著しく火まわりの速度が低下する
ためにその間に大量の臭気やススや一般化炭素
が発生していた。 When igniting, a part of the lamp wick or an attached auxiliary wick is ignited by an ignition heater, etc., and the flame spreads over the entire length of the wick, but this part of the lamp is always supplied with kerosene. It was hot. Therefore, during combustion, some of the fuel components change into tar-like substances due to the high temperature and the presence of oxygen, which accumulates in the fire area, obstructing the supply of fuel to the fire area, or reducing the amount of fuel in the area. Vaporizing capillaries were blocked, making it impossible to ignite or start a fire, or the speed of fire-starting was significantly reduced, producing large amounts of odor, soot, and generalized carbon.

大量の臭気やススや一酸化炭素が発生してい
た。 During combustion, the tar-like substance is similarly generated and accumulated in the fuel vaporization section of the wick, reducing vaporization of the fuel. In other words, this results in a decrease in the amount of combustion. As a result, the air-fuel ratio in the combustion chamber deteriorates, resulting in incomplete combustion, and a large amount of odor, soot, and carbon monoxide are generated even during regular use.
更に前記タール状物質が灯芯に蓄積すること
により、灯芯の上下操作が不能となり、消火し
得なくなる様な危険な状態を招く場合もあつ
た。 Furthermore, the accumulation of the tar-like substance on the wick makes it impossible to move the wick up and down, resulting in a dangerous situation in which it becomes impossible to extinguish the fire.
本発明は上記従来の欠点を解消し、長期間に渡
つて安定した点火、燃焼性能を示す液体燃料燃焼
器を提供するもので、以下その一実施例について
添付図面に基づき説明する。 The present invention solves the above-mentioned conventional drawbacks and provides a liquid fuel combustor that exhibits stable ignition and combustion performance over a long period of time.One embodiment of the present invention will be described below with reference to the accompanying drawings.

５に露出している。 In FIG. 1, reference numeral 1 denotes a combustion tube, in which an inner flame tube 2, an outer flame tube 3, and an outer flame tube 4 are arranged substantially concentrically. The inner flame tube 2 and the outer flame tube 3 each have a large number of air holes 2.
a, 3a are bored, and a combustion chamber 5 is formed between the inner flame tube 2 and the outer flame tube 3. A wick 8 is provided between an inner wick tube 6 and an outer wick tube 7 which are connected to the lower part of the combustion tube 1, and the tip of the wick 8 is exposed to the combustion chamber 5.

ｄは芯押え金具、８ｅは固定用のテープである。 As shown in FIG. 2, the lamp wick 8 is attached to the fire wick 8b with its tip protruding outside the main wick 8a, and the two are separated by a shield 8c such as aluminum foil that prevents the passage of fuel. Also fire wick 8
The lower end of b is the fuel liquid level during combustion (broken line A-A')
It is located higher up and is configured so that when the lamp wick 8 is lowered to extinguish the fire, it is immersed in the fuel (when extinguished, it is immersed in the fuel liquid level up to the point indicated by the broken line B-B'). 8
d is a tailing metal fitting, and 8e is a fixing tape.

As a result, the sum of the opening areas on the side of the fire wick 8b is determined by the main wick 8a.
Approximately 1/3 of the total opening area on both sides.

尽すと燃料の無い、いわゆる空焼き状態になる。 In the above configuration, when a part of the fire wick 8b is ignited by an ignition heater or the like, the flame quickly moves to the entire length of the fire wick 8b, and at the same time, sequentially promotes fuel vaporization in the main wick 8a. The combustion chamber 5 transitions to a stable combustion state. In this combustion state, the lower end of the fire wick 8b is placed above the fuel liquid level as explained in FIG. There is no fuel supply, and when the fuel contained in the fire wick 8b is completely vaporized, there is no fuel, resulting in a so-called dry firing state.

過大燃焼も無く、一酸化炭素発生量も著しく減少
させることができた。 Here, among the plurality of air holes 3a bored in the outer flame tube 3 facing the fire wick 8b, if the sum of the opening areas of those near the fire wick 8b is made larger like the other parts, here A large amount of flame is formed in the combustion chamber 5, causing a sudden increase in the amount of fuel vaporized.
Attempts are made to rapidly increase the amount of combustion, but the upper part of the combustion chamber 5, that is, the upper part of the inner flame tube 2 and outer flame tube 3, is still in a low temperature state and works to suppress the combustion reaction. This will increase odor, soot, carbon monoxide, etc. Therefore, in this embodiment, the fire wick 8 of the air hole 3a provided in the outer flame tube 3 is
Since the number and diameter of the holes near b are reduced to suppress the amount of air, the vaporization of the fuel is gradually promoted, and at the same time the fuel contained in the fire wick 8b is reduced, the vaporization of fuel from the main wick 8a is promoted. The fuel then gradually transitions to stable combustion in a form close to complete combustion. By the way, if you use a kerosene stove and set the ratio of air volume (opening area ratio) near the wick 8 to 1:1 between the inner flame tube 2 side and the outer flame tube 3 side, the change in combustion amount will be (100 %), and the amount of carbon monoxide generated at this time showed a significantly large value as shown in line a of FIG. 3B. Similarly, when the air ratio is 2:1, it becomes like the B line and b line, and when it is further changed to 3:1, like the C line and c line, there is no excessive combustion immediately after ignition, and there is no monoxide. The amount of carbon generated was also significantly reduced.
また燃焼中は火まわり芯８ｂは空焼き状態にあ

た時は火まわり芯８ｂ下端が燃料中に浸漬されて
速かに燃料が吸い上げられるから、上記の性能は
長期間の使用に於ても殆んど変化なく、好ましい
状態を維持することができる。 Also, during combustion, the fire wick 8b is in a dry state, and there is no accumulation of tar-like substances, and when the fire is extinguished, the lower end of the fire wick 8b is immersed in the fuel, and the fuel is quickly sucked up. The above-mentioned performance hardly changes even during long-term use, and can be maintained in a favorable state.

る。 On the other hand, during steady combustion, the fuel vaporizes from the surface of the main core 8a, but the surface of the main core 8a is at a high temperature and in contact with oxygen, so that tar-like substances may be generated and accumulated. In particular, when a portion of the fuel is oxidized or altered, or when high boiling point components are mixed in (e.g. salad oil, diesel oil, machine oil, etc. mixed into white kerosene), tar-like substances are generated and accumulated in large quantities.
The capillary tubes on the surface or inside the main core 8a are closed in a relatively short time. This impairs the vaporization of the fuel, leading to incomplete combustion and the generation of odors, soot, carbon monoxide, and the like. Therefore, in this embodiment, the opening area of the air hole 2a near the main core 8a of the inner flame tube 2 facing the main core 8a is increased to supply a sufficiently large amount of air, thereby ensuring a sufficient amount of fuel vaporization. The temperature of the main core 8a is lowered to suppress the generation of tar-like substances. Furthermore, when the amount of combustion vaporization decreases due to accumulation of tar-like substances, the air-fuel ratio near the main core 8a easily reaches a state where a flame can be formed because a large amount of air is supplied. Therefore, during steady combustion, the state of pore flame formation as shown in FIG. 4A changes to the state shown in FIG. 4B. Therefore, the main core 8a receives a sufficiently large supply of heat,
In addition to promoting the vaporization of the fuel and restoring the combustion amount, tar-like substances are thermally decomposed and removed by the pore flame facing the surface of the main core 8a, and the combustion amount can be maintained stably over a long period of time. It is possible to prevent an increase in odor, carbon monoxide, etc. In particular, if the diameter of the air holes 2a near the main core 8a of the inner flame tube 2 is increased, pore flames will easily form, and it will also be effective in removing tar-like substances. It is also a preferable means to satisfy the above effects by increasing the number of holes and making the pore diameter larger than 3a.

して、著しくクリーニングの効果を発揮し得る。 In addition, increasing the number or diameter of the air holes 2a facing the main core 8a allows the fuel supply to be stopped and combustion to continue, increasing the temperature of the main core 8a and removing tar-like substances. When carrying out so-called dry firing cleaning, a large amount of pomatal flame that promotes the temperature rise of the main core 8a can be obtained, and a remarkable cleaning effect can be exhibited.
尚本実施例に於ては主芯８ａを内側に、火まわ
り芯８ｂを外側にして、内炎筒２に穿けられた空

るが、この逆でも良い。 In this embodiment, the main wick 8a is on the inside, the fire wick 8b is on the outside, and the opening area of the air hole 2a bored in the inner flame tube 2 is made larger than the air hole 3a, but the opposite is true. But it's okay.

The amount of odor, soot, and carbon monoxide generated can be extremely reduced.
