Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a petroleum vaporization and combustion device, and more specifically, it is equipped with two or more vaporizers and burners, and one or more burners can be burned as required. The present invention relates to a petroleum vaporization combustion device.

<Prior art and its problems> In an oil vaporization and combustion apparatus equipped with a plurality of burners and a plurality of vaporizers in order to increase the combustion capacity range of the burner, a plurality of vaporizers with small capacity are used. The total surface area as a whole increases, and as a result, the power consumption of the heater for keeping the carburetor at a constant temperature increases,
There was a problem that running costs were high.

Therefore, an object of the present invention is to provide a petroleum vaporization and combustion device which can minimize heat radiation loss when using a plurality of vaporizers and consumes less electric power and has a low running cost.

<Means for Solving the Problems> In order to achieve the above object, the petroleum vaporization and combustion apparatus of the present invention includes a plurality of vaporizers heated by electric heaters, and vaporizes gas corresponding to each vaporizer. An oil vaporization and combustion device equipped with a plurality of burners for receiving and burning,
The plurality of vaporizers are provided close to each other and are housed in one shielded room.

<Operation> According to the features of the present invention described above, since the plurality of vaporizers are housed in one shielded room, heat dissipation to the outside is prevented,
Power consumption can be reduced. The surface area of the shielded chamber is smaller than that of the shielded chamber provided for each vaporizer, and the heat radiation loss is reduced. Further, since the vaporizers are also placed close to each other in the shielded room, the shielded room itself can be made small, and heat can be kept well in the small shielded room. Therefore, it is possible to reduce power consumption and running cost for heating and holding the vaporizer.

<Embodiment> FIG. 1 is an overall configuration diagram of an embodying device of the present invention, FIG. 2 is a perspective view of essential parts, and FIG. 3 is a plan configuration diagram of the embodying device.

Two burners 11 and 21 are provided in parallel in the combustion can body 2, a blower fan 3 is provided at a lower part of the can body 2, and a heat exchange part 4 of a hot water supply pipe is provided at an upper part thereof. Further, vaporizers 12 and 22 are provided in parallel outside the can body 2, and electric heaters 13 and 23 are provided to the vaporizers 12 and 22, respectively. Further, nozzles 14 and 24 are arranged in parallel from the vaporizers 12 and 22 and face the gas intake ports 11a and 21a of the burners 11 and 21, respectively. 15 and 25 are needle valves for opening and closing the nozzles 14 and 24, and 16 and 26 are the needle valves 15 and 25.
Is a solenoid that moves.

Oil is sent to the vaporizers 12 and 22 from the oil tank 5 by hot water supply pumps 17 and 27 through supply paths 18 and 28, respectively, and vaporized. Nozzle for vaporized gas 1
The air is injected into the gas intake ports 11a and 12a of the burner from 4 and 24, and the ejector effect generated at that time sucks the primary air from the surroundings for combustion. The entire device is covered with an outer casing 1.

The nozzles 14 and 24 are arranged in parallel, and are arranged so as to project into the primary air chamber 30. As shown in FIG. 2, the primary air chamber 30 is provided with nozzle mounting holes 31 and 32 through which the nozzles 14 and 24 are inserted, and the gas of a burner mounted so as to face the nozzles 14 and 24, respectively. Intake port 11a, 21a
Mounting holes 33 and 34 are provided. Further, the inside of the primary air chamber 30 is partitioned by a shielding plate 40 into the mounting holes 31 and 33 side and the mounting holes 32 and 34 side at the central portion. 35, 36
Is an inlet for primary air provided in each isolated room. The intakes 35 and 36 may be provided on both sides of the primary air chamber 30.

Since the shielding plate 40 is provided between the nozzles 14 and 24 as described above, the ejector effect produced by the vaporized gas from the nozzle 24 being ejected toward the gas intake port 21a of the burner 21 is the nozzle 14 and the gas. It does not affect the intake port 11a side. On the contrary, the behavior of the side where the nozzle 14 and the gas intake 11a are located does not affect the nozzle 24 side. That is, vaporized gas and primary air are completely independently supplied to the burner side on both sides separated by the shield plate 40. Therefore, as a result of stable injection of vaporized gas to the burner side and suction of the combustion primary air to the burner side on each side, stable combustion is ensured.

The carburetors 12 and 22 are provided in parallel, and the vaporizers 12 and 22 are appropriately arranged close to each other so that the whole is housed in the shielded room 50. In this case, the vaporizers 12 and 22 are arranged so that the shielded room 50 itself is not in contact with the shielded room 50 as much as possible. Vaporizers 12 and 22 in one shielded room
By putting it in 50, it is possible to effectively prevent the dissipation of heat with a smaller surface area than in the case of covering the vaporizers one by one. Further, since the vaporizers are housed in the shielded chamber 50 in close proximity to each other, the volume inside the shielded chamber 50 is small, and the heat retaining effect by the vaporizers is improved.

In the above-mentioned embodiment, the case where the number of burners, nozzles and vaporizers is two has been described, but it is needless to say that the shielding plate 40, the primary air chamber 30 and the shielding chamber 50 can be similarly applied when there are three or more.

<Effect> The present invention has the above-mentioned configuration, and according to the petroleum vaporization and combustion apparatus of the first aspect, a plurality of vaporizers are brought close to each other and housed in one shielded room. The low-surface-area shielded chamber can effectively prevent heat dissipation from the vaporizer, and can effectively keep the vaporizers mutually warm in the shielded chamber.
