本発明は灯油等の液体燃料を気化室内でガス化して青火
により燃焼させる液体燃料燃焼装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid fuel combustion device that gasifies liquid fuel such as kerosene in a vaporization chamber and burns it with green flame.

来構造の燃焼装置においては下記に列挙する欠点があっ
た。Conventional combustion devices of this type have a thick burner head with an air-fuel mixture injection hole and a throttle wall with a throttle opening in the center, and the burner head is connected to the opening at the tip of the burner body. The vaporization chamber was formed within the burner body. By the way, this combustion device of conventional structure has the following drawbacks.
（１） 絞り用開口を設けた絞り壁部によって気化ガ

つ良好な青火燃焼が行なえなかった。(1) Although the aperture wall with the aperture for the aperture promotes the mixing of the vaporized gas and the combustion air, the mixing condition is still poor, and the red flame is mixed with the blue flame, making it clean and good. It was not possible to perform a blue fire combustion.
（２）肉厚なバーナヘッドと一体に絞り壁部を形成して

熱するのに時間（１３〜１５分）がかかり、点火待ち時
間に長時間を要する欠点があった。(2) Since the aperture wall is formed integrally with the thick burner head, the heat capacity of these burner head members increases, which increases the time required to preheat the electric heater Tehana body at startup. 15 minutes), which had the disadvantage of requiring a long ignition wait time.
（３）噴出孔から噴出する混合気の速度の遅い弱燃焼を
長時間継続させると、絞り用開口を介してバーナヘッド

しやすい状態となり器具の損傷を招（恐れがあった。(3) If the slow, weak combustion of the air-fuel mixture ejected from the nozzle hole continues for a long time, the radiant heat from the burner head will abnormally heat the fuel atomizer in the vaporization chamber through the throttle opening. Combined with the slow flow rate of the gas, it was easy for backfire to occur in the vaporization chamber, potentially causing damage to the equipment.

じき飛ばされて空間中で気化する。The present invention is constructed as described above, and its operation will be explained below. When the heater (5) is energized in advance and the temperature of the chamber wall of the vaporization chamber (9) reaches a high temperature of approximately 300°C, the burner body (2)
The motor (4) is actuated by a temperature sensing device placed in an appropriate location, and fuel is supplied from the fuel supply pipe (c), and the fuel is sprayed into fine particles by the cone a4) and the rotating plate a stirring plate (17). It is blown to the surrounding wall of burner body (2). In this case, since the temperature of the surrounding wall (C) is approximately 300°C, the fine fuel particles are scattered and contact the surrounding wall (2) K, causing nucleate boiling, and some are vaporized there, while others are turned into ultrafine particles. The liquid is then instantaneously flung toward the center of the vaporization chamber (9) and vaporized in the space.

を停止しても気化燃焼が継続できる。The vaporized fuel gas is vaporized while repeating nucleate boiling and atomization in the vaporization chamber (9), and mixes with combustion air to form an air-fuel mixture.
The mixture flows from the gap (to) between the stirring plate aη and the throttle plate (c), through the throttle opening Gυ, and through the flow hole α1 (c) of the baffle plate (to), and then through the ejection holes (7) (7) of the burner head (8). ) to the combustion chamber (1
) and is ignited near the nozzle (force (7)) to form blue combustion flames (c) and (e) and burn. As the combustion progresses, the blue combustion flame 115 causes the burner body (
2) is heated, and the peripheral wall (c) of the burner body (2) maintains a high temperature due to the self-heating, so that vaporization combustion can continue even if the electricity to the electric heater is stopped.

少なくできるものである。In this combustion with blue flame, when the fine particulate fuel that is atomized in the vaporization chamber (9) is reliably vaporized and gaseous and mixed with the combustion air under sufficient pressure, a good blue flame is formed and a clean flame is produced. If part of the particulate fuel is ejected from the nozzle in an unvaporized state, red flame will be mixed with the blue flame. Therefore, in the present invention, the vaporization chamber (
The air-fuel mixture sent out from the baffle plate Gυ is focused once to promote the mixing state, and after this focused air-fuel mixture is brought into contact with the central part of the baffle plate, it is passed through a number of flow holes. ) (2) Since it was made to diffuse by circulating K, even if unvaporized fuel is mixed in the air-fuel mixture sent out from the vaporization chamber (9), this unvaporized fuel will come into contact with the baffle plate ■ and be dispersed. Since it is vaporized by the heat on the surface, unvaporized fuel, which is the main cause of red flames, does not spout out from the ejection holes (7). In addition, the air-fuel mixture is focused at the throttle port 6υ, diffused through the flow holes in the baffle plate, and detoured in the flow path, so the combustion air and vaporized gas are well mixed, resulting in a uniform and clean environment. It produces a blue-green combustion flame, and the amount of carbon in the exhaust gas can be extremely reduced.

I was able to shorten it to just one root.

Because of this baffle plate (l), it is possible to prevent the fuel atomization means in the vaporization chamber (9) from reaching a high temperature of 150°C or higher, and to prevent backfire into the vaporization chamber (9).
