[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a combustion device, particularly a premix combustion device, which can immediately shift body fuel from raw combustion to vaporization combustion. be.

[Prior art] Conventionally, when liquid fuel such as kerosene is vaporized and burned,
It was common to vaporize kerosene, etc. on a high-temperature wall. However, this method requires a heater to heat the wall surface.

Moreover, the preheating time had elapsed, and it was not possible to cause instantaneous combustion.

[Object of the Invention 1] This invention was made in order to eliminate the drawbacks of such conventional devices, and is fixed to nine rotating shafts.

a vaporizer cylinder having a tapered outer wall surface whose open end has a larger surface than its j pressure surface; an oil pipe that supplies liquid fuel to the outer wall surface; the liquid fuel is sprayed and scattered from the open end to cause live combustion; The liquid fuel on the outer wall surface is vaporized by this combustion heat, and a passage for vaporized fuel and air surrounds the vaporization cylinder.

The combustion tube that makes up the passage above, inside this combustion tube.

A combustion plate provided along the open end and having an upper portion thereof as a combustion space, and a combustion plate provided on the combustion plate.

By configuring the combustion device with a flame hole through which a mixed gas of the vaporized fuel and the air is ejected from the passage into the combustion space, it is intended to provide a premix combustion device capable of instant ignition.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The drawing is a longitudinal sectional view showing the main parts of a combustion device according to an embodiment of the present invention. In the figure, (ri is the rotating shaft, (2) is the rotating shaft +1) and is fixed by a tensioning tool (8).

The upper part of the combustion plate is the combustion space I, and the side a is the combustion plate a.
A mixed gas of vaporized fuel and air is ejected from the passage (9) into the combustion space I through the flame hole provided at O. (13 is the open end (
3) and the fuel scattering gap between the combustion plate u0, (the old one is the spark plug, (I61 is the main combustion flame, 07) is the vaporization combustion flame.

Next, the operation will be explained. In the figure, when the rotating shaft (1) rotates, the carburetor cylinder (2) and the fuel receiver cylinder (7) both rotate. Spark plug in the dark! 9 and start the blower (not shown) and turn on
J J louse is allowed to flow along the outer wall surface (5) of the vaporizer cylinder (2) and at the same time, oil is sent onto the fuel pan cylinder (7) from the oil feed pipe (6).

Then, the liquid fuel is diffused in a tapered shape along the outer wall surface (5) of the vaporization cylinder (5) due to centrifugal force, and is further uniformly diffused by the injection action of forced air (9), and is then diffused into the open end (3) of the vaporization cylinder (2). ) The spray is dispersed in finer particles and the main combustion Uυ is caused by the ignition of the ignition plug U. During this main combustion, part of the 9 forced air is blown out through the combustion plate αυ, resulting in complete combustion. The rotating vaporizer cylinder (2) is heated by the combustion heat generated by the above main combustion, and the temperature of the outer wall surface (5) of the vaporizer cylinder (2) is quickly raised to the vaporization temperature. Therefore, the liquid fuel sent onto the outer wall surface (5) is quickly vaporized during the above-mentioned diffusion transition process, becomes a gaseous vaporized fuel, is mixed with the forced wind 9, and a part of it is transferred to the fuel scattering gap αυ. At the same time, most of the remaining mixed gas of vaporized fuel and air is ejected from the flame hole α provided in the combustion plate (lυ) to perform good vaporization combustion aη.

In addition, the vaporization tube (2) is concave with respect to the combustion space IJ4), and the temperature of the vaporization tube (2) is maintained by a balance between combustion of the combustion exhaust gas by the bacterial ring and heat radiation to the air supplied from below. is the optimum temperature for fuel vaporization (200°C for kerosene).
~25G'C). Moreover, the carburetor (2)
As shown in Fig. 1, the fuel tray tube (7) is fixed with a thin gap between the fuel tray tube (7), so that the fuel tray tube (7) is hardly heated, and the liquid fuel is not vaporized here and is Since the fuel is evenly supplied to the vaporization cylinder (2), the fuel is diffused and vaporized very smoothly.

[Effects of the Invention] As described above, according to the present invention, the vaporizer cylinder is fixed to a nine-rotating shaft and has a tapered outer wall surface whose open end is larger than its bottom surface, and a liquid fuel is provided on the outer wall surface. An oil pipe that supplies liquid fuel, a main combustion by spraying liquid fuel from the open end, and a passage for vaporized fuel and air created by vaporizing the liquid fuel on the outer wall surface with this combustion heat, surrounding the vaporization cylinder. , a combustion tube forming the passage; a combustion plate provided inside the combustion tube along the open end and having a combustion space above the combustion plate; and a combustion plate provided on the combustion plate for mixing the vaporized fuel and air. Since the combustion device is configured with a flame hole through which gas is ejected into the combustion space from the above-mentioned passage, it promotes the diffusion and transfer of the supplied liquid fuel, quickly generates vaporized gas, and brings the liquid fuel out of the main combustion state. This has the effect of providing an instant ignition premix combustion device that can immediately shift to vaporization combustion.
