散が不充分となり、混合率が低下して不完全燃焼となり
、また、すす等の発生が増大するという問題があった。In conventional gun-type burners of this kind, internal flame combustion is common, and the spray pattern may become distorted due to dirt or scratches in the spray nozzle IV2, or the discharge pressure of the electromagnetic pump may decrease. There were problems in that the sprayed fuel did not diffuse sufficiently into the air A, the mixing ratio decreased, resulting in incomplete combustion, and the generation of soot and the like increased.
また、内炎燃焼では、燃焼温度があまり高くならないた
め、石油燃焼給湯器などの燃焼率を利用する機器におい
ては、その熱効率が高くないという問題があった。In addition, in internal flame combustion, the combustion temperature does not become very high, so there is a problem that the thermal efficiency of devices that utilize the combustion rate, such as oil-fired water heaters, is not high.
この発明の目的は、スプレーパターンが変動シたり、液
体燃料の噴霧圧が低下したとしても完全燃焼をほぼ維持
し、熱効率が高い液体燃料燃焼装置を提供することであ
る。An object of the present invention is to provide a liquid fuel combustion device that maintains almost complete combustion even when the spray pattern fluctuates or the spray pressure of the liquid fuel decreases, and has high thermal efficiency.
この発明の液体燃料燃焼装置は、液体燃料噴霧ノズルの
前方に配されるものであって、後端に空気吸引口を開口
した筒体と、この筒体の前端開口部に設けたメソシュ状
プレートとを備えたものである。The liquid fuel combustion device of the present invention is arranged in front of a liquid fuel spray nozzle, and includes a cylindrical body with an air suction port opened at the rear end, and a mesoche-like plate provided at the front end opening of the cylindrical body. It is equipped with the following.
この構成による作用は次のとおりである。■燃焼炎は前
記筒体およびメツシュ状ブレートヲ加熱しながら、メツ
シュ状プレートから排出される。The effects of this configuration are as follows. (2) The combustion flame is discharged from the mesh plate while heating the cylinder and the mesh plate.

される。At this time, the interior of the cylinder becomes negative pressure due to the high-speed spray flow from the nozzle, and the externally heated air surrounding the cylinder 8 is sucked into the cylinder from the air suction port at the rear end of the cylinder. (2) Since the cylindrical body and the meso-shaped plate are red-hot by the combustion flame, fuel with a large particle size in the combustion gas produced by the decrease in fuel discharge pressure is instantaneously vaporized when it comes into contact with the cylindrical body and the meso-shaped plate.

いものになる。■ Due to the synergistic effect of (2) and (2) above, blue flame combustion occurs and the combustion temperature becomes sufficiently high. Further, even if the spray pattern varies or the combustion discharge pressure decreases, almost complete combustion is maintained, and soot generation is also prevented. As a result of the above, the thermal efficiency is sufficiently high as a whole.

高温空気である。An embodiment of this invention will be described with reference to FIG. Reference numeral 8 denotes a cylinder (throat pipe) having a trumpet-shaped air suction port 8a opening at its rear end.
A mesh board 9a and a mesh board 9a with only the central part removed.
A frame consisting of a flame holding plate 9b fitted and fixed in the central notch of the
A shunt-like plate 9 is fitted and fixed. The liquid fuel combustion device B configured in this way is used by being placed in front of the air-fuel mixture injection/igniter C similar to that shown in FIG. BF is a blue combustion flame, and 80 is high-temperature air sucked into the air suction port 8a from around the cylinder body 8 and in front of and around the mesh-like plate 9.

料と空気との混合率を増す。At the start of combustion, the liquid fuel sprayed from the nozzle 2 diffuses into the air blown from the fan fiA, and the ignition electrode 3
It is ignited by the discharge spark, creating a combustion flame. The surrounding air is sucked into the cylinder 8 through the air suction port 8a, increasing the mixing ratio of liquid fuel and air.

があっても完全燃焼はほぼ維持される。As the combustion progresses, the cylindrical body 8 and the mesh plate 9 become red hot, the temperature of the suction air A becomes high, the flame becomes a blue combustion flame, and complete combustion occurs. A part of the flame is held by the flame holding plate 9b of the plate 9, and serves as an ignition source when there is a lift of the flame. Complete combustion is almost maintained even if there are variations in the spray pattern.
