Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gun-type burner for vaporizing and burning oil such as kerosene.

Generally, this type of gun-type burner sprays oil from a nozzle to atomize it and ignites the atomized oil to combust it, but in this case, a large amount of combustion air is required, so an air blower device is not used. If combustion is carried out in a combustion cylinder with a porous wall, so-called green-fire combustion becomes difficult, and the amount of air or oil needs to be adjusted, and stable combustion cannot be achieved unless these adjustment devices are attached. Therefore.

A one-rotation scattering plate is installed inside the combustion cylinder inner cylinder, and this rotating scattering plate?
IC11Jd was used to squirt oil from the nozzle and ignite it to heat the rotating scattering plate first.

It is known that the oil ejected is then heated and vaporized into a fine mist, resulting in blue flame combustion. However, in this case, a rotating scattering plate must be provided in front of the nozzle, and its rotational drive source is integrally connected to the shaft of the drive motor in the air blower for supplying combustion air, so the air blower inevitably Since it is an axial fan type, the diameter of the fan has to be increased, which increases the size of the combustion device as a whole and increases the cost.
Furthermore, in this type of burner, if the rotating scattering plate does not have a temperature sufficient to promote the vaporization of the oil, the unvaporized oil will fall as drops, and therefore, when ignited, it is inevitable that so-called red-flame combustion will occur. . Also in front of the nozzle.

There is also a blade body that has fixedly installed elongated holes arranged in a radial manner and a cover plate that provides the opening degree of the elongated holes KFIfrI-.
This blade body suppresses the amount of oil spouted out rather than promoting the vaporization of oil, so when the oil that initially spouted toward the blade body does not pass through the long diameter, it drips as drops. This results in so-called red-flame combustion and stable combustion is not achieved.

Therefore, the present invention has been made with the aim of solving such an IC problem, realizing stable combustion from the beginning of ignition in a gun-type burner, and simplifying its structure. 4111, a nozzle which is fixedly provided in the cylinder inner cylinder and spouts oil toward the inside of the vaporizer cylinder is installed at the back of the oil blowing hole in the combustion cylinder inner cylinder. .

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 shows the central longitudinal section of the gun-type burner for oil vaporization combustion, and Figure 2 shows its front view in Figure 0. 2 is a combustion cylinder, and 2 is an inner cylinder of the combustion cylinder, which is a bottomed cylinder with a porous wall 8 inserted and fixed at the tip of the combustion cylinder l, and an oil blowing hole 3 is provided in the center of the bottom. 4 is a nozzle fixedly arranged facing the blowing hole 3, and 5 is an ignition electrode. The l end of the combustion tube is equipped with an appropriate air blower such as a turbo fan (not shown) VC.
They are connected to form a combustion air supply path 9 to provide forced ventilation to the combustion cylinder inner cylinder 2. On the other hand, on the inside of the combustion cylinder inner cylinder 2, a vaporization cylinder 6 made of a cup-shaped body with an open pressure is fixedly provided. This vaporizer cylinder 6 is fixed to the combustion cylinder inner cylinder 2 by a whipped plate 7 with its open part facing the nozzle 4, and is located in such a position that the oil spouted from the nozzle 4 is accommodated inside the vaporizer cylinder 6. . The vaporizer cylinder 6 is made of a heat-resistant thin metal plate.

In order to quickly raise the specified temperature at the same time as the burner ignites, the wall thickness is set to LO■ in the embodiment, and as shown in Figure 5, it is an integrally molded product with a round bottom shape and a skirt portion 6a. Further, the skirt portion 6aK hole may be bored. Note that the vaporizing cylinder 6 is not limited to a round-bottom cylinder, but may be a rectangular cylinder with a bottom, and if the ignition electrode 5 is arranged in the same manner as the conventional one, the combustion cylinder inner cylinder 2 has a bottom. Since this would be a hindrance, it is placed and fixed at a position sufficiently rearward from the tip of the nozzle 4 to ignite the ejected oil.

Therefore, the oil injected into the blowing hole 3 from the nozzle 4 is ejected at a constant ejection angle so as to be accommodated in the vaporizer cylinder 6, and at the same time! When the fire electrode 5 is ignited, the vaporizer cylinder 6 is immediately heated to a temperature sufficient to vaporize the ejected oil. Therefore, the oil ejected from the nozzle 4 will be heavily vaporized in the vaporizer cylinder 6, and combustion air will be supplied through the gap between the skirt part 6a of the vaporizer *6 and the inner surface of the combustion cylinder inner cylinder 2, resulting in primary combustion. At the same time, a green flame is ejected from the front of the combustion cylinder inner cylinder 2.

↓ On the other hand, Figure 31Il and Figure 4 show other examples of am,
In this example, the combustion cylinder inner cylinder 2a has a stepped configuration in which a plurality of porous cylinders having different diameters are connected, and the vaporization cylinder 6 is fixed to the middle part thereof and is provided facing the nozzle 4. ,
The air blowing area is designed to be large enough to supply a sufficient amount of combustion air to easily cause the atomized or vaporized oil to turn into green flame and burn completely. Also in this example, the vaporizer cylinder 6 has the same properties as the vaporizer cylinder 6 in the previous embodiment.

Therefore, the oil injected into the blow hole 3 from the nozzle 4 is injected between the combustion cylinder inner cylinder 2a and the vaporization cylinder 6, is vaporized in the vaporization cylinder 6, and is combusted with the skirt part 6m of the vaporization cylinder 6. The fuel is primarily combusted between the fuel and the inner surface of the cylinder inner cylinder 2a, and is emitted to the outside.

The flame released was blue and completely burned.

In this way, according to the 9-fire 1jik, it is sufficient to install the combustion cylinder inner cylinder, which is a vaporizing cylinder, in a fixed position facing the nozzle, so it is possible to simplify the configuration and reduce costs, while at the same time starting from the beginning of the first ignition. Stable combustion is achieved, combustion efficiency is good, and only a few additions are needed to the conventional gun-type burner.Since the carburetor cylinder does not rotate, a small motor is sufficient, and the combustion air is exclusively used for combustion.
Turbofans are available to provide energy. In addition, since the vaporization tube is made of thin plate material, it maintains the temperature necessary for atomization of oil in a short time, so incomplete furnace burning such as red flames can be avoided at the beginning of F11 ignition. is configured in multiple stages,
By increasing the area of the porous walls to increase the amount of combustion air supplied, the efficiency of complete combustion is also high, and thus, according to the present invention, a gun-type burner with high stable combustion from the beginning of ignition, similar to the rotary gasification method, is achieved. get.
