Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a vaporization burner of a type that vaporizes and burns liquid fuel, mainly kerosene.

(Prior Art) Conventionally, a fuel diffusion plate is provided in a vaporization cylinder composed of a cylinder extending in a substantially horizontal direction, and fuel supplied onto the fuel diffusion plate is vaporized in the vaporization cylinder, and this is vaporized. An evaporative burner which is mixed with air supplied from one end of a cylinder and supplied to a burner communicating with the other end of the evaporative cylinder for combustion is known from Japanese Utility Model Laid-Open No. 59-175828.

(Problems to be solved by the invention) However, in this case, although the fuel supplied to the diffusion plate spreads on both sides of the diffusion plate, the dispersion in the lengthwise direction of the vaporization cylinder is insufficient. According to this, there is a problem in that the air is not sufficiently vaporized at the beginning of combustion and is supplied to the burner by the wind from the blower to form a so-called red fire that burns and burns.

The object of the present invention is to obtain a vaporization burner without such a defect.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a vaporization burner according to claim 1, wherein a fuel diffusion plate is provided in a vaporization cylinder formed of a cylinder extending in a substantially horizontal direction. The fuel supplied onto the fuel diffusion plate is vaporized in the vaporization cylinder, mixed with air supplied from one end of the vaporization cylinder, and supplied to a burner communicating with the other end of the vaporization cylinder. In the vaporizing burner to be burned, the fuel diffusing plate is gradually lowered toward the upstream side of the flow of the air supplied to the vaporizing cylinder, and the fuel is dispersed and flows down between both side portions and the inner wall surface of the vaporizing cylinder. A fuel passage gap is provided, and the lower surface of the fuel diffusion plate serves as a passage for the air-fuel mixture. In the vaporization burner according to a second aspect of the present invention, a metal mesh is interposed between both side portions of the diffusion plate and the inner wall surface of the vaporization cylinder to form a fuel passage gap through which the fuel is dispersed and flows down.

(Embodiment) An embodiment of the present invention will be described with reference to the attached drawings.

In the drawing, 1 is a vaporization cylinder consisting of a cylinder extending in a substantially horizontal direction,
2 is a fuel diffusion plate provided in the vaporization cylinder 1, 3 is a fuel supply pipe for supplying fuel onto the fuel diffusion plate 2, 4 is a blower connected to one end of the vaporization cylinder 1 via a duct 5, Reference numeral 6 denotes a burner communicating with the other end of the vaporization cylinder 1, and the fuel vaporized in the vaporization cylinder 1 is mixed with the air sent out by the blower 4 and sent to the burner 6 for combustion.

The configuration so far is no different from the conventionally known configuration. In the present invention, the fuel diffusion plate 2
Is gradually lowered toward the upstream side of the flow of the air supplied to the vaporization cylinder 1, and a fuel passage gap is provided between both side edges and the inner wall surface of the vaporization cylinder to disperse and flow the fuel. The lower surface of the diffusion plate 2 serves as a passage 7 for air-fuel mixture.

This will be described in more detail. In the fuel diffusion plate 2, the fuel diffusion plate 2 is composed of a metal plate, and the fuel diffusion plate 2 is formed of the metal plate.
Along the upper surface of the fuel vaporization plate 2 and the inner wall surface of the vaporization cylinder 1 below the fuel diffusion plate 2 are partially deformed and fixed to a cylindrical wire netting 8 by welding or other means and supported by the wire netting. It was designed to be installed in the cylinder 1.

Thus, when the fuel is supplied to the upper surface of the fuel diffusion plate 2 from the fuel supply pipe 3, the fuel is vaporized in a state where the fuel spreads widely on the diffusion plate 2. Most of the vaporized fuel is the diffusion plate 2
The fuel mixed with the air from the blower 3 on the upper side of the blower 3 and sent to the burner 6 side through the lower surface of the diffuser plate 2 as shown by the arrow, and when passing through the lower surface of the diffuser plate 2, the fuel passing through the fuel passage gap is carried. Flows to the burner 6 side.

In the illustrated example, an electric heater 9 is attached to the outer surface of the upper side of the vaporization cylinder 2 to heat and vaporize the fuel on the diffusion plate 2. This is an ignition that operates only at the time of ignition as shown in the conventional example. It is also possible to heat it with a burner for use. When combustion in the burner 6 starts, the vaporization cylinder 1
Is heated by the heat from the burner 6. The numeral 10 indicates the flame of the burner 6.

(Effect of the Invention) Since the present invention is configured as described above, it has the following effects.

In the vaporization burner according to claim 1, the fuel supplied onto the fuel diffusion plate spreads in the length direction of the vaporization cylinder, flows down toward both sides, and spreads thinly and widely on the fuel diffusion plate. Therefore, it is extremely easily vaporized, and mainly vaporizes on the fuel diffusion plate. After the fuel is mixed with air on the fuel diffusion plate, it is supplied to the burner side through the lower part of the fuel diffusion plate, so that the fuel is well mixed and stirred with air, and furthermore, it cannot be vaporized on the fuel diffusion plate. The fuel flowing downward through the fuel passage gap is dispersed when passing through the fuel passage gap, so that it is reliably vaporized and does not cause red fire as in the conventional example. As described above, when the wire net is interposed between the both side portions of the diffusion plate and the inner wall surface of the vaporization cylinder, the fuel passage gap can be easily formed to disperse and flow the fuel.
