本発明は、ガンタイプ・バーナーの改良に関
し、特に青焔燃焼するガンタイプ・バーナーに関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a gun-type burner, and particularly to a gun-type burner that burns green flame.
ガンタイプ・バーナーは、油をノズルから噴霧
して霧化した油に着火して燃焼させるものであ

等を含まない高熱出力の安定した青焔燃焼を可能
とするバーナーについて、多くの試みがなされて
きた。
Gun-type burners spray oil from a nozzle, ignite the atomized oil, and burn it, which produces environmentally harmful soot, NOx , CO, and SO 3 in the exhaust gas.
Many attempts have been made to develop burners that enable stable blue-flame combustion with high heat output and no carbon dioxide.
例えば、ノズルから噴霧して霧化される油滴の
粒径を微細化・均一化したり、燃焼用に供給され

て油量と空気量のバランスがうまく取れず、燃料
と燃焼用空気の混合が不十分で、不完全燃焼によ
る煤やCO等が発生し、また保炎がなされず良好
な燃焼性能が得られないという欠点があつた。 For example, by making the particle size of the oil droplets that are atomized by spraying from a nozzle finer and more uniform, by creating a vortex in the air flow supplied for combustion, or by swirling the air mixture flow to improve ignitability. The aim was to improve flammability. However, with such conventional gun-type burners, stable blue flame combustion is possible only when a certain amount of oil and combustion air are supplied, and combustion with variable oil amount is possible. When adjusting the amount, even if you simply install a device that changes the amount of combustion air to follow the amount of oil, it will not be possible to maintain a good balance between the amount of oil and air over a wide variable range of combustion amount, and the amount of fuel and combustion air will change. The disadvantages were that the mixture was insufficient, soot and CO were generated due to incomplete combustion, and flame holding was not achieved, making it difficult to obtain good combustion performance.
本発明は、上記の欠点を解消するものであつ

The fuel pump No. 1 is operated to spray oil at a constant spray angle from the spray nozzle 6, and the oil is ignited by the ignition electrode 7. Then, the atomized oil starts to burn, and the combustion tube 12, the hollow cylinder for vaporization 13, and the vaporization tube 15 are heated by the combustion heat. moreover,
The oil droplets sprayed from the spray nozzle are vaporized by the heat, and from the combustion within each cylinder 12, 13, 14, the oil droplets are spread along the outer periphery of the hollow cylinder 13 in the direction of the arrow in FIG. Blue flame combustion starts in the combustion section 27 where the water has flowed out. In particular, the annular collision wall 17, the combustion tube 12,
The hollow cylindrical body 13 is heated, and the subsequently sprayed oil droplets are also vaporized while mixing with the combustion air.
Blue flame burning will continue. The secondary air flowing through the vent hole 28 flows into the combustion gas exhaust pipe 9, suppresses overheating of various parts of the burner, and serves to further stabilize combustion.

な青焔燃焼が可能となる。 By the way, the carburetor 15 of the present invention has an intake port 19.
Since it is formed into a truncated cone shape with a smaller diameter on the side and a larger diameter on the discharge port 18 side, the combustion air flows through the vaporization tube 15.
While the gas moves relatively slowly inside, it moves quickly inside the next vaporizing hollow cylinder 13. Therefore, the combustion air is completely combusted, and stable blue flame combustion with high heat output is possible.

れ、燃焼量の調節もできることが確認された。 It has been confirmed through experiments that this gun-type burner can vaporize the air-fuel mixture in a sufficiently stable manner, and the experimental data shows that the theoretical amount of air required for complete combustion is When supplying an air volume approximately 1.5 to 2.5 times the amount of air (10.4 m 3 per oil), stable blue flame combustion is ensured over a much wider range of variable combustion amount than previously known. It was also confirmed that the amount of combustion can be adjusted.
