The present invention relates to a combustor that burns a mixed liquid fuel of methanol and pure water as a liquid fuel.
液体燃料を燃焼する燃焼器（バーナ）は種々の加熱機器

てこの燃焼器の燃料としてはメタノールと純水の混合液
体燃料が使用されている。In a fuel cell power generation system in which a fuel cell and a fuel reformer are combined, this combustor is also provided in the fuel reformer. In a fuel reformer, the reformed gas used as fuel for the fuel cell is generated by reforming the reformed raw material under a reforming catalyst, and a reforming reaction is performed to generate this reformed gas. It is equipped with a combustor to raise the temperature of the reforming catalyst to a temperature suitable for the reforming reaction, and to continuously supply heat to the reforming catalyst since the reforming reaction is an endothermic reaction. . A mixed liquid fuel of methanol and pure water is used as fuel for this combustor.
ところで液体燃料を燃焼させるために燃焼器に液体燃料
を供給する方法としてノズルによる噴霧方式が知られて
いる。噴霧方式は液体燃料をノズルから噴出させて霧状
にし、燃焼空気と混合してイグナイターにより着火して
燃焼するものである。Incidentally, a spraying method using a nozzle is known as a method of supplying liquid fuel to a combustor for combustion. In the spray method, liquid fuel is ejected from a nozzle to form a mist, which is mixed with combustion air and ignited by an igniter for combustion.

燃焼酸化物は極めて臭気の激しいアルデヒドを生成し、
そのまま放出されて環境に悪影響を与えるという問題が
ある。In the above-mentioned nozzle spray method, the liquid fuel ejected from the nozzle does not ignite until it reaches a proper atomization state, so there is a problem that the liquid fuel may fall without being ignited or be released to the outside without being ignited. be. Note that when the liquid fuel from the nozzle is well atomized, ignition is smoothly performed using the igniter. However, in this case, since the directivity of the fuel jet direction is good, if there is an igniter within the directional range, there is an advantage that it will ignite immediately, but because the directivity is good, on the other hand, it does not mix well with the combustion air. Furthermore, since the particles sprayed by the nozzle are relatively large droplets, they have poor combustibility and are discharged to the outside unburned. Additionally, unburned oxides of methanol produce highly odoriferous aldehydes.
There is a problem that it is released as it is and has a negative impact on the environment.
この問題を解決するには、燃料と燃焼空気との混合を充
分に行わせるために、燃焼空気に充分な旋回流を与える
等の構造上の工夫が必要となる。To solve this problem, it is necessary to take structural measures such as providing sufficient swirling flow to the combustion air in order to achieve sufficient mixing of the fuel and combustion air.
またメタノールの燃焼性は、空燃比（λ）がλ−１より
大きく、１に近いところが良く、逆に燃焼空気量をそれ
以上増しても燃焼ガス中にＣＯ，アルデヒドが増加し、
またλが１に近いλ＝１．２〜１．３では燃焼空気量が

流が与えられない。また燃料改質器では燃料がメタノー
ルと純水の混合燃料であるために燃焼条件はさらに悪く
なる。そしてノズル噴霧方式では燃焼量の可変範囲が小
さく使用上の欠点がある。Furthermore, the combustibility of methanol is best when the air-fuel ratio (λ) is greater than λ-1 and close to 1; conversely, even if the amount of combustion air is increased beyond that, CO and aldehydes will increase in the combustion gas.
Further, when λ is close to 1 and λ=1.2 to 1.3, the amount of combustion air is relatively small, so that sufficient swirling flow for improving combustibility cannot be provided. Furthermore, since the fuel in the fuel reformer is a mixture of methanol and pure water, the combustion conditions become even worse. The nozzle spray method has a disadvantage in use because the range in which the combustion amount can be varied is small.

The mixed liquid fuel impregnated in the vaporized material is vaporized and combusted by the combustion heat during combustion.

に燃焼できる。A liquid fuel combustor that burns a mixed liquid fuel of methanol and water includes a porous vaporized body impregnated with the mixed liquid fuel, and combustion air that is placed near the vaporized body and supplies combustion air around it. The mixed liquid fuel is impregnated into the vaporized body, and the impregnated mixed liquid fuel is vaporized and combusted, so that it can be ignited without ejecting unburned droplets when ignited, and when it is ignited, the combustion It vaporizes and burns by receiving heat of vaporization from the heat medium generated by combustion in the combustor.In this case, the heat of vaporization for vaporizing the mixed liquid fuel can be taken from the heat medium generated by combustion in the combustor, so a large amount of heat of vaporization can be obtained. A mixed liquid fuel of methanol and water, which has poor combustion conditions, can be burned well.

The combustion gas transfers heat from the combustion chamber wall 16 around the combustion chamber 15 to the heating fluid flowing through the heating chamber 18, and is exhausted to the outside from the exhaust port 20. The heating fluid is supplied from the supply port 21, heated in the heating chamber 18, and then sent out to the outside via the discharge port 22.
ところで、上記のような燃焼装置は、燃料噴霧式のよう

空気供給量は滑らかに増減させなければならない。Furthermore, due to the structure of the above liquid fuel combustor, even if the mixed liquid fuel of methanol and water is increased or decreased in a pulsed manner, the amount of vaporized gas will not increase or decrease in a pulsed manner. If the amount of combustion air supplied is increased or decreased in a pulsed manner in the same way as the amount of liquid fuel supplied, the air-fuel ratio (λ) will change significantly, making it impossible to obtain good combustion. Therefore, the combustion air supply amount must be smoothly increased or decreased in contrast to the liquid fuel supply amount, which increases and decreases in a pulsed manner.

る。In FIG. 2, combustion air is supplied as shown at 24, and the glow heater is turned on as shown at 25 to heat the vaporized body 2. After that, mixed liquid fuel is supplied to the vaporized body and ignited and burned. Please note that once ignition and combustion occur, the glow heater is turned off.
Make it. When the amount of liquid fuel supplied during combustion changes in a pulsed manner as shown at 23, the amount of combustion air is changed not in a pulsed manner but smoothly in accordance with the amount of liquid fuel supplied which changes in a pulsed manner as shown in 24. By doing this, the amount of combustion air increases or decreases in proportion to the amount of vaporized gas of the mixed liquid fuel, so the air-fuel ratio is maintained at an air-fuel ratio that achieves good combustion as shown in 26, and therefore the combustion of the mixed liquid fuel Sexuality improves.

浸された混合液体燃料がなくなれば消火する。When the combustion is stopped and the fire is extinguished, the supply of liquid fuel is stopped as shown at 23, but at this time, the mixed liquid fuel still remains in the vaporized body 2. Therefore, if the amount of combustion air is reduced smoothly as shown at 24a and the combustion is stopped, the remaining mixed liquid fuel impregnated into the vaporized material will be vaporized and burned. Even during this combustion period, the air-fuel ratio is maintained at the ratio described above, and good combustion is performed. The fire is extinguished when the mixed liquid fuel impregnated with the vaporized substance is exhausted.

燃焼メタノール。As is clear from the above description, according to the present invention, liquid fuel is produced from a porous vaporized body impregnated with a mixed liquid fuel of methanol and water, and a combustion air chamber that supplies combustion air around the vaporized body. By configuring the combustor and vaporizing and burning the mixed liquid fuel impregnated in the vaporized body, at the time of ignition, the mixed liquid fuel is impregnated with the vaporized body, vaporized, and combusted. No fuel droplets are discharged to the outside, which improves ignitability. Also, during combustion, a large amount of vaporization heat can be given to the mixed liquid fuel from the combustion heat during combustion, improving combustibility and reducing the amount of combustion. This has the effect of making it easier to vary over a large range. In addition, due to improved combustibility, CO1 and unburned methanol are contained in the combustion exhaust gas.
アルデヒド等の有害なガスが極めて少なくなるので、環
境に悪影響を与えないという効果もある。Since harmful gases such as aldehydes are extremely reduced, there is also the effect that there is no negative impact on the environment.
