【発明の詳細な説明】
本発明は、引火性の大なるアルコールを水と混
合した混合燃料を燃料として用いた液体燃料燃焼
装置に関するものであり、その熱交換効率を高め
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid fuel combustion device that uses as fuel a mixed fuel in which highly flammable alcohol is mixed with water, and is intended to improve the heat exchange efficiency thereof.
従来のアルコールと水を混合した混合燃料を用
いた液体燃料燃焼装置では、水とアルコールを同
時に燃焼部へ供する為に、排気中に過剰な水分を
含み、この水分は燃焼熱を受けて気化した状態の
ままで器具外へ放出されるのでその熱交換効率が
悪いという欠点を有するものであつた。 In conventional liquid fuel combustion devices that use a mixed fuel of alcohol and water, because water and alcohol are supplied to the combustion section at the same time, excess moisture is contained in the exhaust gas, and this moisture is vaporized by the heat of combustion. It has the disadvantage that heat exchange efficiency is poor because it is discharged outside the appliance in its original state.
本発明はこのような従来の欠点を解消したもの
であり、以下その一実施例を添付図面を用いて説
明する。 The present invention eliminates these conventional drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.
図に示す気化部１には、アルコールと水との混
合燃料を熱板２上の傾斜上方へ滴下させる送油管
３が設けられている。 The vaporization section 1 shown in the figure is provided with an oil feed pipe 3 for dripping a mixed fuel of alcohol and water onto a hot plate 2 in an upwardly inclined direction.
前記熱板２は適当な加熱手段１０によつて、常
に水の沸点100℃とアルコールの沸点の間の任意
の温度に保たれている。このような熱板２へ滴下
した混合燃料は、瞬時に昇温し、アルコールを主
成分としたアルコール蒸気を発生する。そして熱
板２上にはアルコールを微量含有する水が残留
し、熱板２の傾斜に沿つて傾斜下方の排水口４よ
り排出される。また前記アルコール蒸気は気化部
１に接続している導管５を通過して、燃焼部６に
到り、適宜空気と混合して燃焼する。 The hot plate 2 is always maintained at an arbitrary temperature between the boiling point of water, 100° C., and the boiling point of alcohol, by a suitable heating means 10. The temperature of the mixed fuel dropped onto the hot plate 2 rises instantaneously, and alcohol vapor containing alcohol as a main component is generated. Water containing a small amount of alcohol remains on the hot plate 2 and is discharged along the slope of the hot plate 2 from the drain port 4 located below the slope. Further, the alcohol vapor passes through a conduit 5 connected to the vaporization section 1, reaches the combustion section 6, mixes with air as appropriate, and burns.
またポンプ７で混合燃料の滴下量を変えれば、
燃焼量を変えることができるが、多量に滴下した
場合、先に滴下した混合燃料に混らないことが必
要である。即ち、熱板２上に、アルコール濃度の
低い水分が残留している所に、更に次の滴下が行
われれば、低濃度の液相が熱板２を覆い、十分
に、アルコール蒸気を発生することができなくな
るからである。 Also, if you change the amount of mixed fuel dripping with pump 7,
The combustion amount can be changed, but if a large amount is dropped, it is necessary that it does not mix with the mixed fuel that was dropped earlier. That is, if the next drop is performed on the hot plate 2 where water with a low alcohol concentration remains, the low concentration liquid phase will cover the hot plate 2 and generate enough alcohol vapor. This is because it becomes impossible to do so.
従つて、常に熱板２に液相のない状態で混合燃
料を滴下しなければならず、そのような状態にす
れば熱板２と液滴の接触熱伝達は最良となり、十
分なアルコール蒸気と、より純粋に近い水を分離
することが可能となる。 Therefore, it is necessary to always drop the mixed fuel onto the hot plate 2 in a state where there is no liquid phase, and in such a state, the contact heat transfer between the hot plate 2 and the droplets is the best, and sufficient alcohol vapor and , it becomes possible to separate more pure water.
この目的の為に熱板２の傾斜は設けられている
のである。 The slope of the hot plate 2 is provided for this purpose.
前記排水口４より排出された水分は熱板２の温
度まで昇温しており、本実施例ではこの温水を熱
交換部８に於て前記送油管３と接触させて、混合
燃料と熱交換させることにより、予め混合燃料の
温度を高める構成とした。 The temperature of the water discharged from the drain port 4 has risen to the temperature of the hot plate 2, and in this embodiment, this hot water is brought into contact with the oil pipe 3 in the heat exchange section 8 to exchange heat with the mixed fuel. By doing so, the temperature of the mixed fuel is raised in advance.
このため、熱板２を加熱する加熱手段１０の消
費電力量を大巾に節約できる。又前記熱交換部８
を通過した水は器具外に排出する。 Therefore, the amount of power consumed by the heating means 10 for heating the hot plate 2 can be significantly reduced. Further, the heat exchange section 8
The water that has passed through is discharged outside the equipment.
以上のように本発明によれば、水とアルコール
の混合燃料を用いるので安全性が高く、また混合
燃料の水分を予め分離してより純粋なアルコール
だけを燃焼部へ供給するので排気中の水分は過剰
なものとならず、その分熱交換効率を高めること
ができる。 As described above, according to the present invention, since a mixed fuel of water and alcohol is used, safety is high, and since water in the mixed fuel is separated in advance and only pure alcohol is supplied to the combustion section, moisture in the exhaust gas is reduced. is not excessive, and the heat exchange efficiency can be increased accordingly.
またアルコールは水と非常に混合しやすいもの
であるが、本発明を用いれば、多少水が混入して
も燃焼に全く悪影響を与えることはない。 Further, although alcohol is very easily mixed with water, if the present invention is used, even if some water is mixed in, the combustion will not be adversely affected at all.
また石油を用いずに暖房・給湯等が行え、今後
の石油不足に対して有効なものである。 Additionally, heating and hot water supply can be performed without using oil, which will be effective against future oil shortages.
