本発明は、灯油等の燃料オイルをノズルから噴霧して燃

現するための方法に関するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for achieving good ignitability in a gun-type burner that sprays and burns fuel oil such as kerosene from a nozzle. .
(従来の技術〉
従来のガンタイプバーナとしては、例えば第4図に示す

。(Prior art) An example of a conventional gun type burner is the one shown in FIG. The oil for spraying is stored in an oil tank e and is pressurized by an electromagnetic pump g and supplied to a nozzle b via an oil supply line f.
このようなバーナaを着火するに際して、ノズルbの噴

ようなバーナaの電磁ポンプgには緩点火用のものを用
いて、燃焼開始時のオイル噴霧量を少なくすることによ
り緩点火を実現している。When igniting such a burner a, if there is a large amount of oil sprayed from the injection port C of the nozzle b, gradual ignition may not be achieved, a large amount of soot may be generated, a loud ignition noise may be produced, or even vibration combustion may occur. Since this type of burner a has poor ignition properties, such as the occurrence of ignition, the electromagnetic pump g of such a burner a is designed for slow ignition, and slow ignition is achieved by reducing the amount of oil sprayed at the start of combustion.
しかし、一般に緩点火用の電磁ポンプgは非常に高価で
あり、したがってこれを用いたバーナaのコストも高く
なるという課題がある。However, the electromagnetic pump g for slow ignition is generally very expensive, and therefore the cost of the burner a using it is also high.
本発明はこのような課題を解決することを目的とするも
のである。The present invention aims to solve such problems.
なお第4図の符号りはオイルストレーナを示す。Note that the reference numerals in FIG. 4 indicate oil strainers.

を少なくするものである。(Means for Solving the Problems) The means for solving the problems described above will be explained based on FIGS. 1 to 3 corresponding to Examples. The method of the present invention includes:
A bypass nozzle l is provided as an oil spray nozzle, and the bypass line 2 of this nozzle 1 is connected to the electromagnetic pump 5 of the oil supply line 4 to the nozzle 1 via the electromagnetic proportional control valve 3.
When the burner 7 is ignited, the gun type burner 7 has returned to its proper position on the upstream side of the oil tank 6 and on the downstream side of the oil tank 6.
The amount of oil sprayed from the injection port 8 of the nozzle 1 is reduced by driving the electromagnetic proportional control valve 3 to be fully open or close to fully open.

て、ノズル1の噴射口8から噴霧したオイルに、点火プ
ラグ9の放電により着火して、バーナ7の燃焼を開始さ
せる。(Operation and Examples) When the fuel oil stored in the oil tank 6 is pressurized by the electromagnetic pump 5 and supplied to the bypass nozzle 1 via the oil supply line 4, a part of it is sprayed from the injection port 8. However, the oil that was not sprayed returns to the bypass line 2,
The oil flows into the oil supply line 4 via the electromagnetic proportional control valve 3, and is again supplied to the nozzle 1 by the electromagnetic pump 5. Then, the oil sprayed from the injection port 8 of the nozzle 1 is ignited by the discharge of the spark plug 9, causing the burner 7 to start combustion.

できるもので、これを制御することによって、バイパス
糸路2へのノズルlからの還流オイル量、したがって噴
射口8からの噴霧オイル量を、広い範囲にわたって無段
階に調節することができる。The electromagnetic proportional control valve 3 can linearly change the opening degree by changing the voltage applied to the excitation coil 10, and by controlling this, the flow from the nozzle l to the bypass yarn path 2 is reduced. The amount of recirculated oil, and therefore the amount of oil sprayed from the injection port 8, can be adjusted steplessly over a wide range.

えることができる。Therefore, when igniting the burner 7, if a large voltage is applied and driven to the excitation coil 10 so that the electromagnetic proportional control valve 3 is fully open or close to fully open, the electromagnetic pump 5 can supply the nozzle 1 with a large voltage. As most of the oil flows back to the bypass line 2, the amount of sprayed oil from the injection port 8 can be extremely reduced. Therefore, if this oil is ignited by the discharge of the spark plug 9, it will be a slow ignition and ignite. It is possible to suppress the occurrence of soot, combustion noise, or vibrational combustion.
このように、電磁ポンプ5の出力圧にはかかわらず、バ
ーナ7を緩点火とし得るので、電磁ポンプ5は、例えば
運転開始から、その出力圧が一定の、比較的安価なもの
でも充分に使用可能である。In this way, the burner 7 can be ignited slowly regardless of the output pressure of the electromagnetic pump 5, so even a relatively inexpensive electromagnetic pump 5 whose output pressure is constant from the start of operation can be used satisfactorily. It is possible.
そして、バーナ7が着火した後、適当な時間経過したな
らば、電磁比例制御弁3の開度を調節することによって
、バーナ7を所望の燃焼状態にすることができる。Then, after a suitable period of time has elapsed after the burner 7 is ignited, the burner 7 can be brought into a desired combustion state by adjusting the opening degree of the electromagnetic proportional control valve 3.

いう効果がある。(Effects of the Invention) As described above, according to the ignition method of the present invention, it is possible to slowly ignite a gun type burner without using an expensive electromagnetic pump for slow ignition, so that soot and combustion noise are generated during ignition. The present invention has the effect of providing a gun-type burner with excellent ignitability, which has little vibration and does not cause oscillating combustion, at a relatively low cost.
