本考案は、灯油その他の液体燃料を初期の生燃
焼状態から蒸発気化して気化燃焼させる気化バー
ナに関する。[Detailed Description of the Invention] The present invention relates to a vaporization burner that evaporates and burns kerosene or other liquid fuel from an initial raw combustion state.

空気を自動的に気化体内に吸引導入せしめて燃料
の拡散移行作用と混気ガスの起成ならびに逆火燃
焼の防止を行わせる上で甚だ有益である。 Conventionally, as shown in Japanese Utility Model Publication No. 52-32985, a gaseous body and a gas chamber provided on the inner periphery of a combustion cylinder are communicated via an intake cylinder, and an intake cylinder communicating with the intake cylinder is provided in the gas chamber. A blower impeller equipped with a kerosene vaporizing burner is positioned directly connected to a rotating shaft inserted into the combustion cylinder, and the intake cylinder is connected to the outside through an intake port provided in the combustion cylinder. This is extremely useful in automatically drawing air into the vaporizer to prevent fuel diffusion, generation of mixed gas, and backfire combustion.

気化体内部を直線的に流通してしない一定濃度の
混気ガスを起成させることができず、その結果、
安定した気化燃焼を長期に亘り継続させることが
できない欠点があつた。 However, as mentioned above, the combustion air generated by the suction action of the blower impeller is not restricted in any way, and flows inside the vaporized body in a straight state inside the fixed intake cylinder. When the combustion air is introduced by suction, the combustion air does not sufficiently stir and mix with the mixed gas generated inside the vaporized body, and generates a mixed gas with a constant concentration that does not flow linearly inside the vaporized body. As a result,
The drawback was that stable vaporization combustion could not be continued for a long period of time.

A mixed gas passage is provided, an air supply window is opened on the distal end side, and an inner cylindrical body with a pressure-feeding fan connected to the proximal open side is provided to integrate the rotary vaporizer, the inner cylindrical body, and the pressure-feeding fan. The inner cylinder body is rotatably connected, and the inside of the inner cylinder body is divided into a rotating blowing chamber communicating with the discharge port of the pressure-feeding fan, so that the inner cylinder body and the pressure-feeding fan are simultaneously rotated by the rotational operation of the rotary vaporizer, The swirling combustion air generated by the pressure fan is immediately blown into the swirling blower chamber, and the rotating inner cylinder provides even more swirling performance, allowing the accurately swirling combustion air to be sent to the blowing window. By regulating the amount of air blown to a constant level, the mixed gas passage is self-supplied, and the mixed gas is thoroughly stirred and mixed with the vaporized gas flowing through the mixed gas passage, resulting in a completely homogeneous mixed gas. The purpose of this invention is to obtain a vaporizing burner that can continue stable vaporizing combustion over a long period of time by generating fumes while An example will be described below.

である。 Note that it is preferable that the base end side of the inner cylindrical body 6 be located near the boundary between the combustion tube 1 and the ventilation tube 2. 12 directly sends the swirling combustion air sucked in the ventilation passage 2 into the swirling blowing chamber 9 from the discharge port 14, and forces the swirling combustion air to be further swirled by the inner cylinder 6. This is a pressure-feeding fan for supplying air from the air-feeding window 10 into the mixture gas passage 8 while regulating the amount of flow to be constant. It is integrally mounted on the side so as to be located within the ventilation passage 2, and this connects the boss portion 13 of the pressure fan 12 to the hollow rotating shaft 3.

に持続されるものである。 In FIG. 1, when starting the burner, if the rotary vaporizer 5 and the inner cylindrical body 6 are rotated at high speed by the hollow rotating shaft 3, the pressure feeding fan 12 integrated with the inner cylindrical body 6 is also activated. The swirling combustion air generated by rotating at high speed is swirled directly into the swirling blower chamber 9 from the discharge port 14, and further inside the swirling blower chamber 9, the rotational action of the inner cylinder body 6 is imparted with swirling properties. After
The mixed gas is introduced from the air supply window 10 into the rotating mixed gas passage 8 under a certain amount of rotation. Therefore, oil line 4
When the fuel inside is injected from the oil injection port 16, the fuel becomes fine particles by the fuel splashing bodies 17 and is sprayed into the mixed gas passage 8. This atomized fuel passes through the mixture gas passage 8 and is ejected from the gas outlet 11 to the inner surface of the combustion tube 1, so that when it is ignited by the spark plug 18, live combustion occurs within the combustion tube 1. . When raw combustion occurs in the combustion tube 1, the rotary vaporizer 5 is heated by the combustion flame, and the rotary vaporizer 5 rapidly reaches the fuel vaporization temperature. Therefore, the fuel sprayed in fine particles from the fuel oil scattering body 17 into the mixed gas passage 8 comes into contact with the inner circumferential surface of the rotary vaporizer 5 and is vaporized. This evaporated gas is a constant amount that is sent from the swirling air blowing chamber 9 through the air blowing window 10 into the mixed gas passage 8, and is combined with the swirling combustion air and the rotating mixed gas passage 8. The mixed gases are stirred and mixed in the combustion chamber to form a homogeneous mixed gas of a constant concentration, which is then ejected from the gas outlet 11 into the combustion cylinder 1, resulting in vaporization combustion. After the transition to vaporization combustion, the rotary vaporizer 5 continues to be heated to a high temperature by the combustion flame, so that vaporization combustion is maintained in a stable state.

果を奏する。 In short, the present invention provides a rotary vaporizer 5 with a closed tip and an open base end in a combustion tube 1 with an open tip and a proximal side connected to the ventilation passage 2, and an inner side of the rotary vaporizer 5. The rotary vaporizer 5 is equipped with an inner cylindrical body 6 having a mixed gas passage 8 at its distal end, an air supply window 10 opened at its distal end, and a pressure fan 12 connected to its proximal open side. The cylindrical body 6 and the pressure fan 12 are connected so that they can rotate together, and the interior of the inner cylinder 6 is divided into a swirling air chamber 9 that communicates with the discharge port 14 of the pressure fan 12, so that the rotary vaporizer 5, the inner cylindrical body 6 and the pressure feeding fan 12 are simultaneously rotated, and the combustion air for generating the mixed gas is swirled and introduced directly into the swirling blowing chamber 9 from the discharge port 14, and then the air is fed. The air can be blown from the window 10 toward the mixed gas passage 8 which is rotating under a swirling state while regulating the amount of air to a constant level, and as a result, the generated mixed gas and combustion air can be stirred and mixed. The combustion air introduced into the swirling blowing chamber 9 is forcibly given swirling properties by the rotation of the inner cylinder 6, so that the stirring and mixing with the vaporized gas is further improved. This results in the effect that a homogeneous mixed gas can be stably atomized over a long period of time, and good vaporization combustion can be continued.
