Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves raw combustion of fuel injected into a gas generating cylinder along with forced air, heating the gas generating cylinder by the raw combustion flame, evaporating and vaporizing the injected fuel, and then performing vaporization combustion. The present invention relates to a vaporizing burner in which the state of

Previously, the applicant arranged a combustion tube below the gas generation tube,
It has a structure in which a gas generating tube and a combustion tube are connected to each other, and when the fuel is injected co-injected with forced air from the air outlet at one end of the gas generating tube, the combustion flame is ejected from the flame opening of the lower combustion tube. We developed a vaporization burner that heats the upper gas generation cylinder, vaporizes the fuel in the gas generation cylinder, and then evaporates and burns it in the lower combustion cylinder. The effect of this is being demonstrated.

By the way, in the above-mentioned vaporizing burner, the combustion tubes are stacked one above the other directly below the gas generating tube, so the height is high compared to the capacity of the burner. It is difficult to install and use it in equipment,
Perhaps because of the severe restrictions on its range of use, the gas generator is constantly shattered by the strong combustion flames ejected from the nozzle of the combustion tube located directly below it, causing it to become red-hot. In addition to the risk of burning out in a relatively short period of time, the fuel injected into the gas generating cylinder also has the disadvantage that it forms a ball of water on the inner surface of the cylinder and is not completely vaporized, often resulting in incomplete combustion. there were.

In view of the above, the present invention has combustion tubes arranged side by side on the same plane on both sides of the gas generation tube, so that the burner can be improved compared to the conventional one in which the gas generation tube and the combustion tube are stacked vertically. The height of the gas generator can be significantly reduced, and even small or short equipment can be installed without restrictions, making it possible to use it over a wide range of areas. The radiant heat of the combustion flames ejected from the flame port can rapidly heat the fuel to a temperature suitable for vaporizing it, thereby preventing short-term burnout of the gas generating tube, and also ensuring complete vaporization of the fuel, ensuring proper vaporization. This is an attempt to provide a vaporizing burner that can maintain a combustion state,
The configuration of the present invention will be described below with reference to preferred embodiments shown in the drawings.

In FIGS. 1 to 5, reference numeral 1 denotes a gas generating tube, and one end of the gas generating tube 1 is connected to a blowing tube 2. As shown in FIG.

3, 3 are combustion tubes, and the combustion tubes 3, 3 are arranged in parallel on both sides of the gas generating tube 1 on the same plane,
One end of the combustion tubes 3, 3 is closed, and the inside thereof is a gas chamber 4,
4, and the other end is connected to the other end of the gas generating cylinder 1 through a communication cylinder 5.

On the upper half of the Joetsu combustion tubes 3, 3 and on the surface facing the gas generating tube 1, there are many slit-shaped nozzles 6, 6...
・ is perforated on the outer peripheral surface opposite to that of the combustion tubes 3, 3.

A flame cover plate 7 having upper and lower overhangs is attached.

This flame stopper plate 7 serves to stabilize the combustion section by directing it inward.

The flame nozzles 6, 6, . . . of the combustion tube 3.degree. 3 may have a slit shape, a small circular hole, or any other suitable shape.

The CU inside the blower cylinder 2 and the oil pipe 8 are piped toward the gas generating cylinder 1, and the tip oil injection port 9 faces in a neutral position near the connection part with the gas generating cylinder 1.

Further, an opening window 10 is formed in the blower tube 2 at a portion corresponding to the tip oil port 9 of the oil feed pipe 8, and a lid plate 11 is applied to the opening window 10 from the outside. The periphery of 11 is detachably attached by set screws 12, 12, . . . .

An ignition plug 13 for generating main combustion is mounted on the inner surface of the lid plate 11, and a pair of electrodes of the ignition plug 13 face near the front of the oil injection port 9 at the tip of the oil pipe 8.

14 is an ignition window for generating vaporization combustion, and this ignition plug 1
4 is provided near one end of one combustion tube 3.

Note that the air supply port of the air tube 2 is connected to the air blowing side of a forced air generator (not shown).

FIGS. 6 and 7 are other examples of what has been described above.

That is, two combustion tubes 3, 3' and 3,3' are arranged in parallel on both sides of the gas generating tube 1 on the same plane as the gas generating tube 1, and these two combustion tubes 3, 3' on each left and right side are arranged in parallel. and 3
, 3' are connected to the gas generating cylinder 1 through a communication cylinder 5', and has the same effect as the previous one except that the combustion section is enlarged.

Note that one end of the combustion tubes 3, 3' and 3, 3', which are arranged in parallel on both sides of the gas generating tube 1, is closed, but it is also possible to make the left and right sides communicate with each other through the communication tube 15. .

Next, the operation of the present invention will be explained.

Now, if forced air is blown into the gas generating cylinder 1 from the blower cylinder 2, and fuel is injected into the gas generating cylinder 1 from the oil injection port 9 at the tip of the oil pipe 8, and ignited by the ignition plug 13, gas will be generated. Live combustion occurs in cylinder 1.

The combustion section by this raw combustion enters the combustion tubes 3, 3 from the gas generating tube 1 through the communication tube 5, and the flame nozzle 6,
The combustion section blows out from 6..., and the gas generating cylinder 1 is heated by the combustion section from both sides thereof.

Next, when the gas generating cylinder 1 reaches the vaporization temperature, the fuel supply from the oil pipe 8 is temporarily stopped, and the spark of the ignition plug 13 is stopped to eliminate the main combustion state, and then gas is generated from the oil pipe 8 again. When fuel is injected into the cylinder 1, the fuel immediately evaporates and vaporizes, and is stored in the gas chambers 4 of the combustion cylinders 3, 3 through the communication cylinder 5 while being mixed with forced air.

Then, the mixed gas is ejected from the flame nozzles 6, 6, . Mixing with the wind is maintained, and the state of vaporization and combustion is maintained.

In the embodiments shown in FIGS. 6 and 7, the combustion tubes 3', 3'[
Mixed gas is also sent to the nozzles 6, 6, . . . , and combustion portions are also generated.

By the way, since the gas generating tube 1 and the combustion tubes 3 and 3 (including the combustion tubes 3 and 3 in other examples) are provided on the same plane, the burner has a flat shape as a whole, and its height has been significantly reduced. It gets lower.

Therefore, it can be installed and used without any problem even in small or short equipment, and its usable range is extremely wide.

Further, the gas generating cylinder 1 has combustion cylinders 3 located on both sides thereof,

Although it is partially exposed to the combustion part generated by ..., it is mainly heated by the radiant heat, so the gas generating cylinder 1 is not overheated to a red-hot state and is heated to a temperature suitable for vaporizing the fuel. be done.

Therefore, not only can short-term burnout of the gas generating tube 1 be prevented, but the fuel injected into the gas generating tube 1 will never form a hot ball on its inner surface and suffer from poor vaporization, and the fuel will always be completely vaporized. Be able to maintain proper vaporization and combustion conditions.

Incidentally, since the ignition plug 13 provided inside the blower tube 2 is attached to the cover plate 11 of the opening window 10, maintenance, inspection, replacement, etc. of the ignition plug 13 can be easily and accurately performed by simply opening and closing the cover plate 11. In addition, since the ignition plug 13 is provided in the blower tube 2 through which forced air always flows, there is no risk of burnout of the ignition plug 13.

In short, the present invention forms gas chambers 4 on both sides of a gas generating cylinder 1 whose one end is connected to a blower cylinder 2, and has flame openings 6, 6,
