本発明は、家庭用石油ストーブから工業窯炉までの幅広
い範囲における液体燃料の燃焼に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to the combustion of liquid fuels in a wide range of applications, from household kerosene stoves to industrial kilns.
（従来の技術）
液体燃料の燃焼には、ストーブのように暖房を目的とし
た燃焼や、被加熱物を加熱するための燃焼、あるいは内
燃機関のような動力発生機関としての燃焼等がある。(Prior Art) Combustion of liquid fuel includes combustion for the purpose of heating as in a stove, combustion for heating a heated object, and combustion as a power generating engine such as an internal combustion engine.
従来の燃焼は、液体燃料を直接気化させて燃焼させるか
、または噴霧装置によって一度細かい霧状に***させて
燃焼させるかのいずれかの燃焼方法が用いられている。Conventional combustion methods include either directly vaporizing liquid fuel and combusting it, or splitting it into fine mist using a spray device and then combusting it.

０）に代表される。The former type of direct vaporization combustion is widely used in general household oil stoppers, and includes the pot type (Japanese Unexamined Utility Model Publication No. 58-35713) and the wick type (Japanese Unexamined Utility Model Publication No. 58-203307, Unexamined Japanese Unexamined Patent Publication No. 1988-60-).
64134 publications) or vaporization type (, MS30°3
0).
ポット式は燃料を蒸発皿によって蒸発燃焼させる方式で
、気化部と燃焼部が一体となっている。The pot type uses an evaporating dish to evaporate and burn the fuel, and the vaporizing part and combustion part are integrated.
芯式は燃料タンクの中に挿入したアスベスト等の芯に燃
料を吸収して蒸発しやすいようにその表面積が拡大され
ている６着火すると炎は芯金部に広がり燃焼を継続する
。In the wick type, a wick of asbestos or other material inserted into the fuel tank absorbs the fuel and its surface area has been expanded to facilitate evaporation.6 When ignited, the flame spreads to the core and continues combustion.
また、気化式は燃料を気化室又は気化管内で蒸発さ・せ
た後、燃焼部で燃焼させる方式で、気化部と燃焼部が区
分されているものである。In addition, the vaporization type is a method in which the fuel is evaporated in a vaporization chamber or a vaporization tube, and then burned in a combustion section, and the vaporization section and the combustion section are separated.

はかられる方式である。On the other hand, spray combustion is used in some household kerosene stoves, but is mostly used in industrial furnaces and boilers. This combustion atomizes the liquid fuel into fine oil droplets,
This method increases the contact area with air and promotes evaporation and combustion reactions.

に、点火時や消火時の臭いはいかんともしがたく、石油
ストーブは臭いのするものであるといった観念のあるこ
とは周知の事実である。Commonly used oil burners are rotary burners, jet burners (steam spray, air side [mechanical spray)], special burners (gun type high pressure spray, low pressure side [etc.).They are also used as a kind of ignition device. There are also examples of turning liquid fuel into foam and igniting it with an electric spark. (
(Japanese Patent Publication No. 49-42018, Japanese Patent Application Laid-open No. 47-38368) (Problems to be solved by the invention) In combustion methods such as pot 2, which directly vaporizes liquid fuel, the combustion chamber is fully lit after ignition. Until then, it is difficult to rapidly increase the amount of combustion, and in oil stoves and the like, it takes a considerable amount of time until the ignition level is reached. Furthermore, it is a well-known fact that there is a perception that kerosene stoves are smelly, and that the smells produced when igniting or extinguishing a fire are unbearable.
特に消火時の臭いは安全性との兼合いもあって、速やか
に消す必要があり（例えば、ＪＩＳでは地震等の振動ま
たは誤まって器具を転倒させた場合には１０秒以内で消
えることを義務づけている）、その反動として、消火時
の臭いがかえって強くなる傾向にあるのが実情である。In particular, the odor when extinguishing a fire must be extinguished quickly for reasons of safety (for example, JIS stipulates that odors must be extinguished within 10 seconds due to vibrations such as an earthquake or when equipment is accidentally knocked over. As a reaction to this, the fact is that the smell when extinguishing a fire tends to become stronger.
これは、消火操作後、それだけ早く炎がなくなることで
あり、例えば石油ストーブの場合には、消火後も灯芯や
ポットから燃料蒸気が蒸発しており、それがまだ熱い燃
焼筒内を通過する時に、刺激臭を有するアルデヒド等に
酸化されるため強い臭いとなり、不快感を与える等の問
題となっている。This means that the flame disappears quickly after the extinguishing operation. For example, in the case of a kerosene stove, fuel vapor evaporates from the wick or pot even after the extinguishing operation, and when it passes through the still hot combustion cylinder. , it is oxidized to aldehydes and the like that have a pungent odor, resulting in a strong odor and causing discomfort.
一方、噴霧燃焼方式として、幾種類もの燃焼器はあるも
のの、いずれも油滴が空気と共に噴霧される時に、油滴
群は広い粒径分布を有し、各粒子は互いに相互作用を呈
しながら、異なった方向に異なった速度で移動する。On the other hand, although there are many types of combustors for the spray combustion method, in all of them, when oil droplets are sprayed together with air, the oil droplets have a wide particle size distribution, and each particle interacts with each other. Move in different directions and at different speeds.
従って、噴霧燃焼は均一性を欠き、油滴は蒸発と混合の
過程が不十分のまま、火炎前面に到達し拡散炎にかこま
れることになり、不拘−炎となり易い。従って、被加熱
物の局部過熱を起し易い等の問題がある。Therefore, the spray combustion lacks uniformity, and the oil droplets reach the front of the flame without being sufficiently evaporated and mixed, and are surrounded by a diffusion flame, which tends to result in an unconfined flame. Therefore, there are problems such as local overheating of the object to be heated.
また、油を噴霧するための設備が必要となり、動力費等
のランニングコストも高くなる欠点があった。In addition, equipment for spraying oil is required, which has the disadvantage of increasing running costs such as power costs.

はなりえない。Japanese Patent Publication No. 49-42018 and Japanese Patent Publication No. 47-3836
The example presented in Publication No. 8 functions as an ignition device and cannot be used as a means for stably performing continuous combustion.

のである。(Means for Solving the Problems) The present invention provides a new combustion method for improving the above-mentioned drawbacks. In other words, the present invention provides a method for converting liquid fuel into foam and continuously burning it in a combustor in order to freely adjust the amount of combustion immediately after ignition of a kerosene stove, to prevent odor during ignition and extinguishing, and to improve the unrestrained flame of spray. In particular, the effect is remarkable when applied to kerosene stoves.
ここで、泡沫とは、液体燃料の薄膜で空気や酸素等の気
体を包囲した気泡の集合体をいう。Here, the foam refers to an aggregate of bubbles surrounding a gas such as air or oxygen with a thin film of liquid fuel.
この泡沫の燃焼において、注目すべき特性は、従来と違
った状態で、燃料と空気との接触面積を増大させること
ができ、蒸発と燃焼反応の促進がはかられることである
。A noteworthy characteristic of this foam combustion is that it is possible to increase the contact area between the fuel and air, which is different from conventional methods, and promotes evaporation and combustion reactions.
以下、本発明を図面にもとづいて説明する。Hereinafter, the present invention will be explained based on the drawings.
第１図に示す設備において、燃料タンク１から供給管８
を通して、集泡筒３内の所定の高さまで燃料油を供給す
る。集泡筒３内には、発泡させるための焼結金属エレメ
ント２が配置されていると共に、その上部外側には燃焼
用２次空気を供給するための風箱４が設置されている。In the equipment shown in FIG. 1, from the fuel tank 1 to the supply pipe 8
Through this, fuel oil is supplied to a predetermined height inside the bubble collecting cylinder 3. A sintered metal element 2 for foaming is disposed inside the bubble collecting tube 3, and a wind box 4 for supplying secondary air for combustion is installed outside the upper part thereof.
焼結金属エレメント２は多孔質であり、これに気体供給
管６から気体を吹き込むことによりエレメントの孔から
燃料油中に気体が供給され、燃料油（灯油、軽油等）・
は発泡しなから集泡筒３内を上昇する。なお、エレメン
ト２は金属に限らず、多孔質のセラミックス等も利用で
きる。The sintered metal element 2 is porous, and by blowing gas into it from the gas supply pipe 6, the gas is supplied from the pores of the element into the fuel oil, and the fuel oil (kerosene, light oil, etc.)
The bubbles rise inside the bubble collecting cylinder 3 without being foamed. Note that the element 2 is not limited to metal, and porous ceramics or the like may also be used.
この際、同時に燃焼用２次空気管７から風箱４を介して
、燃焼に必要な空気を供給し燃焼させるものである。か
くして、泡沫９は容易に安定した燃焼を継続するという
結果を得た。At this time, air necessary for combustion is simultaneously supplied from the secondary air pipe 7 for combustion via the wind box 4 to cause combustion. In this way, the result was obtained that Foam 9 easily continued stable combustion.
そして、気体供給管６から供給する空気量を多くして泡
沫生成量を増加させると共に、２次空気管７からの空気
量を増やすことにより燃焼量を容易に増加させることが
できる。また、泡沫生成量を一定にして２次空気管７か
らの空気量を増加させるほど、火炎は短かくなるという
結果も得た。Then, by increasing the amount of air supplied from the gas supply pipe 6 to increase the amount of foam generated, and by increasing the amount of air from the secondary air pipe 7, the amount of combustion can be easily increased. It was also found that the flame became shorter as the amount of air from the secondary air pipe 7 was increased while keeping the amount of foam generated constant.
このような結果は、泡沫が火炎面と焼結金属エレメント
２との間で液体燃料の薄膜が蒸発して、泡沫中の空気と
、それ以外の泡沫に寄与しない空気および２次空気との
混合により、安定燃焼するものと考えられる。Such a result is caused by the fact that a thin film of liquid fuel evaporates between the flame surface and the sintered metal element 2, and the air in the foam is mixed with other air and secondary air that does not contribute to the foam. This is thought to result in stable combustion.
これはガス燃焼における１次空気と２次空気の比率を変
えて、火炎形状等の燃焼特性を制御する方法と似ている
。なお、本発明は直接気化燃焼におけるアスベスト等の
芯を利用して点火する方式に比べ、生成した泡沫に直接
点火源を接触させるだけで容易に着火できる。This is similar to the method of controlling combustion characteristics such as flame shape by changing the ratio of primary air to secondary air in gas combustion. In addition, in the present invention, compared to a method of igniting using a wick of asbestos or the like in direct vaporization combustion, ignition can be easily ignited by simply bringing an ignition source into direct contact with the generated foam.
また、消火も気体供給管６への空気の吹込みを停止する
ことで泡沫はなくなり、直ちに消火する。Furthermore, when extinguishing a fire, the foam is eliminated by stopping the blowing of air into the gas supply pipe 6, and the fire is extinguished immediately.
従って、消火後の燃料蒸気の発生もなく臭いは感じない
。Therefore, no fuel vapor is generated after the fire is extinguished, and no odor is felt.
このように、燃料を泡沫化して燃焼することにより、気
体供給管６からの空気吹込量を調整することと、および
２次空気管７からの空気供給量を変えることで、燃焼量
と火炎形状等の燃焼特性を自在に制御することができる
。また、従来技術では成し得なかった石油ストーブでの
即暖、臭いなし燃焼を可能とした。In this way, by combusting the fuel into foam, by adjusting the amount of air blown from the gas supply pipe 6 and by changing the amount of air supplied from the secondary air pipe 7, the combustion amount and flame shape can be adjusted. It is possible to freely control combustion characteristics such as It also enables immediate heating and odorless combustion in kerosene stoves, which was not possible with conventional technology.
次に本発明における２次空気管７から別に空気を供給し
なければならない理由について説明する。Next, the reason why air must be separately supplied from the secondary air pipe 7 in the present invention will be explained.
灯油や軽油等の液体燃料のみで得られる泡沫の発泡倍率
（泡沫体積／液体燃料体積）が、通常５〜５０倍程度で
ある。しかしながら完全燃焼させるに必要な空気のａ・
要倍率は約９０００倍であり、それに泡沫中の空気量は
到底及ばないためである。The foaming ratio (foam volume/liquid fuel volume) of foam obtained only with liquid fuel such as kerosene or light oil is usually about 5 to 50 times. However, the amount of air required for complete combustion is
This is because the required magnification is about 9,000 times, and the amount of air in the foam is nowhere near that.
しかし、燃焼には気体供給管６から供給した空気が、泡
沫中にとどまらないでそのまま燃焼用空気として、直接
利用できる分もあるので、２次空気管７から供給される
空気量は、理論燃焼空気量の６０〜９８％でよい、これ
は通常、工業窯炉等で使用されているノズルミックスタ
イプのガスバーナ燃焼とほぼ同程度である。However, for combustion, some of the air supplied from the gas supply pipe 6 does not remain in the foam and can be used directly as combustion air, so the amount of air supplied from the secondary air pipe 7 is The amount of air may be 60 to 98%, which is approximately the same level as the nozzle mix type gas burner combustion normally used in industrial kilns.
また、液体燃料にポリマーや界面活性剤を添加して発泡
倍率を高めることにより、より燃焼反応を促進すること
も可能である。It is also possible to further promote the combustion reaction by adding a polymer or a surfactant to the liquid fuel to increase the expansion ratio.
一方、被加熱物を加熱するためのバーナ燃焼に、この泡
沫燃焼を利用する場合には、軽油を除いて他の液体燃料
のみで生成させた泡沫では、泡沫径の均一性や発泡性の
安定化にやや問題がある。従って、発泡剤として、液体
燃料にポリマーや界面活性剤あるいはそれらの混合物、

加および表面張力を低下させて、発泡性を改善すること
で安定した泡沫生成が可能となり、バーナから噴射され
る泡沫の燃焼は安定した均−炎を保ち、被加熱材の局部
加熱を防止する効果を発揮することができる。On the other hand, when using this foam combustion for burner combustion to heat the object to be heated, foams generated only with other liquid fuels other than light oil will not have uniform foam diameter or stable foaming properties. There is a slight problem with the conversion. Therefore, as blowing agents, polymers, surfactants, or mixtures thereof can be added to liquid fuels.
Alternatively, by mixing light oil with good foaming properties to increase the surface viscosity and lower the surface tension, it is possible to generate stable foam by improving foaming properties, and the combustion of the foam injected from the burner is stable. It is possible to maintain an even flame and prevent local heating of the heated material.
（実施例）
次に第１図の燃焼装置で燃焼した時の実施例について詳
しく説明する。(Example) Next, an example in which combustion is performed using the combustion apparatus shown in FIG. 1 will be described in detail.

熱したニクロム線を接触させて点火した。Kerosene 5 at a temperature of 20°C is passed from the fuel tank 1 through the supply pipe 8.
Air 12j! is supplied from the zero-order secondary air pipe 7 through the wind box 4 to a predetermined height in the bubble collecting tube 3. /min while supplying air at a rate of about 31/min from the gas supply pipe 6 to form bubbles 9 with a particle size of 1 to 3 on the liquid surface in the bubble collecting tube 3.
The foam was filled up to a height of approximately 1100 a, and a red-hot nichrome wire was brought into contact with the top of the foam 9 to ignite it.
この時の燃焼状態は青白い火炎で、完全燃焼状態を安定
して継続した。The combustion state at this time was a pale blue flame, and the complete combustion state continued stably.
また、２次空気管７からの空気量を減少させていくと、
その火炎は徐々に橙色を呈する様子がうかがえた。この

The amount of air was also increased to 55j'/min for combustion.
この時は、火炎長さは若干長くなるが、やはり火炎は青

その後、気体供給管６からの空気を停止すると直ちに泡
沫は消滅し、消火した。この時には臭いの発生もなかっ
た。Thereafter, when the air supply from the gas supply pipe 6 was stopped, the foam immediately disappeared and the fire was extinguished. At this time, no odor was generated.
このように、本発明の泡沫燃焼は、燃焼能力を可変する
ことの容易さおよび火炎形状の制ｊｎ性等が容易にでき

また、以上の説明において、吹込む気体は一般に空気を
使用するが、更に燃焼効率を高めるために酸素単体ある
いは空気への酸素エンリンチガス等も使用できる。Furthermore, in the above description, air is generally used as the gas to be blown in, but in order to further improve the combustion efficiency, oxygen alone or oxygen enriched gas for air can also be used.

泡沫の生成方法を限定するものではない。In addition, in this experiment, foam was generated by the so-called air supply method in which air is introduced into the element 2 having a hole of a certain diameter, but there are also other methods such as stirring method, shaking method, boiling method, depressurization method, and solubility reduction method. Alternatively, there are methods that combine these methods, but the present invention does not limit the foam generation method.
また、燃焼装置の外で所望の泡沫を生成させた後、燃焼

制御も簡単にできる。(Effects of the Invention) As explained in detail above, the present invention is a method of turning liquid fuel into foam and burning it in a combustor, which does not require the use of a wick during ignition, compared to the conventional method of direct vaporization and combustion. Not only can it be easily ignited, but it can also easily control the amount of combustion immediately after ignition.
従って、ストーブに適用した場合の即暖を可能とした。Therefore, when applied to a stove, immediate heating is possible.
