【発明の詳細な説明】
本発明は灯油等の液体燃料燃焼装置に関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for burning liquid fuel such as kerosene.
周知の圧力噴霧式バーナでは、粒子分布が２０〜２００
μとばらついているにもかかわらず、そのまま旋回又は
、擾乱を与えた燃焼用空気と強制混合させ燃焼させてい
た。In the well-known pressure spray burner, the particle distribution is between 20 and 200
Despite the variation in μ, the mixture was swirled as it was or was forcefully mixed with the disturbed combustion air and burned.
そのため油滴の蒸発速度の差による燃焼速度の乱れが空
気振動を起し騒音を生じたり、煤や一酸化炭素が発生し
易かった。As a result, the combustion rate is disturbed due to the difference in the evaporation rate of the oil droplets, which causes air vibration, which causes noise and tends to generate soot and carbon monoxide.
そこで本発明では、圧力噴霧された燃料粒子の一部を気
化器の周囲で燃焼させ、その燃焼熱により油滴群を気化
させる事により予混合を容易にし燃焼効果を上げかつ低
騒音のバーナの提供を目的とするものである。Therefore, in the present invention, some of the pressure-sprayed fuel particles are combusted around the vaporizer, and the combustion heat is used to vaporize the oil droplets, thereby facilitating premixing, increasing the combustion effect, and creating a low-noise burner. It is intended for the purpose of providing.

で構成される気化器８が設けられている。A cylindrical fuel vaporizer 6 and a fuel diffuser 7 are provided at the top of the pot 3.
A vaporizer 8 is provided.
一方９は、外箱２とポット３より形成されてなる燃焼空
気通路であって、該通路９には送風機１０が連設されて
おり、ポット３の周壁には適宜穿孔された補助燃焼用空
気供給小孔１１、一次空気供給小孔１２が設けられる。On the other hand, reference numeral 9 denotes a combustion air passage formed by the outer box 2 and the pot 3. A blower 10 is connected to the passage 9, and auxiliary combustion air is provided through appropriate holes in the peripheral wall of the pot 3. A small supply hole 11 and a small primary air supply hole 12 are provided.
さらに、ノズル挿入筒５に穿孔された点火用空気供給小
孔１３よりポット３内に入る空気の乱れをなくす作用を
持たせた、整流板１４が燃焼空気通路９内に置かれてい
る。Furthermore, a rectifier plate 14 is placed in the combustion air passage 9, which has the effect of eliminating turbulence in the air entering the pot 3 through the small ignition air supply hole 13 bored in the nozzle insertion tube 5.
又該通路９の上端は内方に傾斜した燃焼リング１５で閉
塞されており、該リング１５には多数の二次空気噴出小
孔１６が穿孔されている。The upper end of the passage 9 is closed by an inwardly inclined combustion ring 15, and the ring 15 has a large number of small secondary air injection holes 16 perforated therein.
なお図中１７は点火栓、１８は電磁ポンプを示す。In the figure, 17 indicates a spark plug, and 18 indicates an electromagnetic pump.
次に動作について、図面にもとづいて説明する。Next, the operation will be explained based on the drawings.
通電するとポンプ１８、点火栓１Ｔは同時に作動する。When energized, the pump 18 and the spark plug 1T operate simultaneously.
従って燃料タンク（図示せず）より流出した燃料油は、
電磁ポンプ１８に至り、ここで加圧され、噴霧ノズル１

火される。Therefore, fuel oil spilled from the fuel tank (not shown) is
The electromagnetic pump 18 is pressurized here, and the spray nozzle 1
The water is ejected into the pot 3 in an arc shape and is ignited by the ignition plug 17.
又、ポット３内の空気は燃焼必要量に対して充分低くお
さえであるので、炎面は瞬時にしてポット３外にも移動
する。Moreover, since the air inside the pot 3 is kept sufficiently low relative to the amount required for combustion, the flame surface instantly moves outside the pot 3 as well.
一方ポット３上部の気化器８の周囲の小孔１１より噴出
する空気のエジェクタ効果により、ポット３内に噴出す

分で加熱させ気化器８内を高温雰囲気にすると共に気化
用補助燃焼の高温廃ガスと混合させることにより気化器
８内に噴霧された燃料を気化する。On the other hand, due to the ejector effect of the air ejected from the small holes 11 around the carburetor 8 in the upper part of the pot 3, fine particles among the fuel particles ejected into the pot 3 are attracted and the fine particles are combusted around the carburetor 8. Accordingly, the fuel vapor 6 is divided into 1 to 2
The fuel sprayed into the vaporizer 8 is vaporized by heating the vaporizer 8 to create a high-temperature atmosphere within the vaporizer 8 and mixing it with high-temperature waste gas from auxiliary combustion for vaporization.
この液体燃料の気化ガスにポット３上部の一次空気供給
小孔１２より一次空気を与え燃焼リング１５の二次空気
供給小孔１６より二次空気を与えて燃焼させる。Primary air is supplied to the vaporized gas of the liquid fuel from the primary air supply hole 12 at the top of the pot 3, and secondary air is supplied from the secondary air supply hole 16 of the combustion ring 15 to cause combustion.

り熱分解されて可燃性ガスとなり、より高負荷燃焼が可
能となった。In this manner, the liquid fuel combustion device of the present invention burns a portion of the atomized fuel particles around the outer periphery of the fuel vapor, and uses the combustion heat as vaporization heat to convert the remaining fuel particles into vaporized gas. As a result, the mixture with combustion air is extremely good and a uniform concentration distribution is obtained, making it possible to lower the excess air ratio compared to conventional oil combustion machines, which improves combustion noise and improves vaporization. By mixing high-temperature waste gas from auxiliary combustion with vaporized gas, the vaporized gas is thermally decomposed by the high-temperature waste gas and becomes flammable gas, making it possible to perform higher-load combustion.
