Title of invention

Liquid fuel combustor with wick

5 This invention relates to a liquid fuel combustor that can vary the amount of fuel vaporized from a wick that sucks up liquid fuel such as petroleum and easily adjust the amount of combustion.o

BACKGROUND ART-A conventional wick type liquid fuel combustor such as an oil stove has a configuration in which an upper portion of a wick protrudes between an inner flame tube lO and an outer flame tube. By changing the amount of fuel, the amount of fuel vaporized from this wick can be varied, and this is the reason! ) The amount of combustion was adjusted. However, if the projecting height of the wick was too low, the adhesion of tar to the wick was promoted, as is well known.i> The amount of CO in the exhaust gas increased, so the combustion amount could be substantially controlled. Did not. In addition, the recent deterioration in petroleum circumstances has led to the heavy use of kerosene that will be obtained in the future. It is becoming increasingly difficult to completely burn them with 'things.

0 In such a wick-type liquid fuel combustor, a large amount of tar adheres to the upper part of the wick when used for a long period of time. (Even if burned oil, such as white kerosene and altered oil mixed with vertical oil and engine oil (oxidized white kerosene), excessive tar is generated in the burner portion of the wick, and the amount of combustion extremely reduced. , 5: The fire cannot be extinguished because the wick cannot be moved up and down. • There was a title. For this reason, in the past, the so-called baking operation, in which the supply of liquid fuel to the lamp was cut off to continue combustion, was performed, but the internal flame near the lamp core was reduced so that a large amount of co and odors were generated during ignition. Since the diameter of the air holes provided in the cylinder and the outer flame cylinder is reduced, the air

5 The amount was small, so the temperature of the wick was unlikely to rise during emptying, and even with this open burning, it could adhere and kill tar.

DISCLOSURE OF THE INVENTION

In view of this, the present invention provides an inner flame cylinder or an outer flame cylinder in which at least one of the inner flame cylinder and the outer flame cylinder is detachably provided with a cylinder having a large number of pores below 下部 θ.

D. It is intended to provide a liquid fuel combustor whose combustion amount can be easily adjusted.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 2 is a half sectional view of a liquid fuel combustor in an embodiment.

BEST MODE FOR CARRYING OUT THE INVENTION

.- In Fig. 1, a cylindrical core outer cylinder 3 is attached via a packing 2 to the upper opening of the fixed tank 1 that stores white kerosene used as an example of liquid fuel. Have been. A cylindrical core guide tube 4 is welded to the lower five openings of the fixed tank 1 so that the • A cylindrical light core ⁵ is provided on the outer periphery of the tube 4 so as to be vertically movable. The wick 5 serves to suck up the white kerosene in the fixed tank 1 and vaporize it from above. The outer pans 3 and 7 above the core outer cylinder 3 and the core guide cylinder 4 have cylindrical outer flame cylinders S, inner flame cylinders 9, outer cylinders 10 and 5 and a substantially disk-shaped net. A combustion cylinder 14 composed of ¹¹ , a coil ¹² , and a disk-shaped partition plate ¹³ is mounted. Each of the outer flame tube S and the inner flame tube 9 is provided with a large number of air holes 15, and the air that has flowed in from the air holes 5 is mixed with white kerosene vaporized from the upper part of the wick 5, and the external flame Combustion takes place in the combustion chamber 16 formed between the cylinder S and the inner flame cylinder 9.

Here, the inner flame cylinders ¹ and 7 and the outer flame cylinder 18 are detachably attached to the lower part of the inner flame cylinder 9 and the outer flame cylinder 8 of the combustion cylinder 14 as shown in Fig. 2. Is done. Also, you provided with each rather large number of air holes ¹ 9 of FIG. 3 in the inner flame cylinder "! 7] ?, the total area the height of the inner flame cylinder 1 Ryo 5 of the air hole 1 9 The total area of a plurality of air holes ¹⁵ provided in the lower portion of the inner flame cylinder ⁹ having the same dimensions as Α is larger than the total area of the plurality of air holes ^{15. Further} , as shown in FIG. The total area of the air holes 20 is also equal to the total area of the air holes 15 provided in the lower part of the outer flame cylinder S having the same dimensions as the height A of the outer flame cylinder 18. ¾O The lower part of the inner and outer flame cylinders 9 and 8 is press-fitted into the outer flame cylinder 1 and the inner flame cylinder 18 described above, but the screw coupling and the bayonet coupling In this case, it is possible to prevent protrusions from coming out in the combustion chamber 16 as much as possible in order to prevent turbulence in the fuel and deterioration of the material department.

In 5 above configuration, the liquid侔燃family retardant ^ vessel is shown in FIG. ¹ £ ·-The inner and outer flame cylinders 17 and 18 were used with the inner and outer flame cylinders 17 and 18 attached as shown in Fig. 2. As a result, the overall height of the fuel cylinder 14 changes, and the draft in the combustion chamber 16 changes, and the amount of combustion increases or decreases accordingly. That is, the amount of combustion can be adjusted. However, by attaching and detaching the outer flame cylinder 18 and inner flame cylinder 1T]), the flow rate of air near the wick 5 changes, so that kerosene of different quality can be more completely burned. As a result of various tests, kerosene with many components with a low boiling point has a small opening area for air intake near the wick 5 to reduce the air flow rate and contains many components with a high boiling point It is known that kerosene will produce less tar when the air flow is increased by increasing its opening area], and it is known that it will burn completely.], Inside and outside By attaching and detaching the flame tubes 17 and 18, the air flow rate can be changed to cope with the combustion of different kerosene. This is the inner and outer flame cylinder

1 7, 1 have variously prepared et to the air hole ¹ 9, 2 also of 0 different Ru of total opening area of the S, when vMedia.Creating exchange, yo can sufficiently correspond to Ruru. Due to this, even if kerosene is becoming heavier in the future, it is necessary to replace the entire equipment if it is necessary to replace the inner and outer flame cylinders. Make sure that you can deal with it by replacing the

-In addition, as in the case of this example, if the inner cylinder 1a and the outer cylinder 1S with large total opening area of the air holes 19, 20 are used, the air inflow near the wick 5 when these are installed When the wick 5 becomes large, the swelling of the wick 5 becomes active near the wick 5, the change of the wick 5 is high, and the

CMFI • It is easy for the file to disappear. For this reason, wicks that had become unusable due to the adhesion of tar can be reused by supplying white kerosene to wick 5 and baking them.

Meanwhile Among the aforementioned, outer flame cylindrical body ¹ §, 1 S will be this is also further doubling inexpensive der Re Invite effect. Therefore, the inner and outer flame tubes 17 and 1S should be as inexpensive as possible and their height should be as low as possible. However, the projecting height of the tip of the wick 5 should be high so as not to significantly affect combustion. In other words, the height of the tip of the wick 5

If by increasing the height of 8, and the above佤, outer flame Quai body ¹ §, ¹ and S, of the combustion cylinder 1 4, and隱間occurs in seams between the outer flame cylinder 9, 8 However, it has the advantage of not significantly affecting combustion.

Next, FIG. 5 shows another embodiment. In this embodiment, the outer flame cylinders 8 and 9 of the combustion cylinder 14 are divided into upper and lower parts, and the lower inner part and the outer flame part are placed inside. In this embodiment, the inner and outer flame cylinders are attached to the inner and outer flame cylinders S and 8 and the outer flame cylinders ¹ and 3 are used. Since the flame cylinder 1S is covered by the outer cylinder ¹ O, the inner and outer flame cylinders # ¹ T and 18 are discomforted, and the combustion is disturbed by the wind. There is an advantage.

Figs. 6 and 7 show an example in which only the outer flame tube S or only the inner flame tube 9 is divided into upper and lower parts. Effect can be obtained just by changing the hole area

Also, on the top of the wick ⁵ , 芯 ^ ¾ ¾ ceramic] ¾ ¾ べべべ用いる用いる用いる用いる用いる用いる. The effect is further increased.

Industrial applicability

As described above, according to the present invention, the draft of the combustion chamber is changed by the attachment and detachment of the inner and outer flame tubes 侔, so that the fuel vaporization amount is varied without changing the projection height of the wick, and the combustion amount is changed. It is possible to completely burn at least two types of liquid fuel by changing the amount of air near the wick by attaching the inner and outer flame cylinders.
