Abstract

PURPOSE:To permit to obtain a larger variable width in the amount of heat and improve the characteristics of exhaust gas by a method wherein the heights of inner and outer flame cylinders are constituted so as to be equal substantially and the outer cylinder is provided with an air choking section. CONSTITUTION:A wick guide tube 4 is located below the inner flame cylinder 1 and a wick outer tube 5 is located below the outer flame cylinder 2 while a wick 6 is interposed between the tubes 4, 5 so as to be slidable in up-and-down direction. A flame expanding plate 9, integral with a cylindrical red-heat body 10, is fixed to an inner flame cylinder cap 8 by spot welding or the like. The inner flame cylinder 1 and the outer flame cylinder 2 are formed so as to have the same height. Further, the air choking section 14 is provided at a part of the outer cylinder 3, which is opposing to the upper ends of the inner and outer flame cylinders 1, 2. According to this constitution, air, which rises up through a space between the outer flame cylinder 2 and the outer cylinder 3, is supplied to the flames in an ample amount, and perfect combustion, which generates small amount of carbon monooxide or the like, may be effected since sufficient air is supplied. The variable width of calorific value, which is adjusted by regulating the amount of evaporation from the wick by moving the height of wick into vertical direction, may be obtained in a large range.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a combustion tube for an oil combustor.

Conventional structure and its problems The combustion tube of the conventional double-tube kerosene stove is a low-load type stove, and although it is possible to change the calorific value to some extent by adjusting the upper F of the wick, the range is very flexible. If you exceed the range
There were many problems, such as an increase in the occurrence of tar, and tar buildup on the core, making it unusable. -For example, in a /85 wick type stove, by changing the wick height from 12 to 7 mm and 5 mm, the output power can be changed from 2200 Kcal/h to 1.
800 Kc=, 1/h to 400 Kcal/h l
If the wick height is lowered, the CO2 will exceed the JIS regulated 00℃02=0.002.
There was a problem in that it caused

The invention of the monthly failure EJEI was made in view of this problem, and the purpose is to greatly reduce the fluctuation of the heat generating part and improve the exhaust gas characteristics by placing a fence around the high-load combustion cylinder. This is what I did.

Structure of the Invention In order to achieve the above-mentioned purpose, the present F! In J'4, the inner flame tube and the outer flame tube are configured to have approximately the same height, and an air throttle part that protrudes toward the outer flame tube is provided in a portion of the outer tube that faces the upper end of the outer flame tube.

Example theory 1:11. j An example of this will be described below with reference to FIG.

In Fig. 1, 1 is an inner flame tube, 2 is an outer flame tube set at the same height as the inner flame tube 1, and 31)-It is an outer tube, and two cross pins 13 constitute a double tube. .

1. At F of the inner flame tube 1, there is a wick guide tube 4, and below the outer flame tube 2 there is a wick outer tube 5, and a lamp wick 6 is interposed in the middle, making it slidable up and down. . An inner flame tube cap 8 is placed on the upper end of the small inner flame tube 1, and this cap has a plurality of six 8a
have. Inner flame cylinder camp 8 has a cylindrical red-hot body 10
A flame expansion plate 9 integrated with the flame expansion plate 9 is fixed by spot welding or the like, but the flame expansion plate 9 has no holes or the like and has a structure that does not allow air to pass through. Further, an outer cylinder cap 12 is attached to the upper end of the incandescent body 10 via an outer cylinder ring 11.
The glass tube 7 on the outer tube 3 is fixed via this outer tube camp 12. This outer cylinder ring 11 is located on the upper end surface of the incandescent body 10 and the glass cylinder 7, making this part a closed space, and in the center, a hole 11 with a diameter smaller than 1° of the incandescent body
It has a. The 14 parts that were cut were the inner and outer flame tubes of the above outer tube 3.
The air constriction part, which also serves as a support for the glass tube, is provided in the part facing the end of the glass tube, and injects the air that has risen between the outer flame tube 2 and the outer flame tube 3 into the flame formed above the inner and outer flame tubes. It is for the purpose of

To explain the combustion mechanism in the second section, when the wick 6 is cut out with a dial or the like (not shown) and a green flame is lit, the wick 6 vaporizes the absorbed kerosene due to its own heat. Air necessary for combustion is supplied from inside the core guide tube 4 and through the middle between the outer tube 3 and the outer flame tube 2. The air thus supplied and the vaporized kerosene are mixed together, then a flame is formed in the small hole provided in the outer flame tube 2, and while the mixture is being combusted, the unburned mixture is further drawn out by the draft effect of the heat. raise it to

Here, the air rising inside the inner flame cylinder 1 is ejected in the circumferential direction from the inner flame cylinder cap 8 having a relatively large 68a.
The mixture diffuses and mixes with the air-fuel mixture that has flowed between the inner and outer flame cylinders, forming a large flame around the entire circumference. is provided, and a large amount of air rising from between the outer flame cylinder 2 and the outer cylinder 3 is supplied toward the flame. Therefore, since sufficient air can be supplied to the flame, it is possible to achieve complete combustion with little generation of carbon monoxide, etc., and it is also possible to adjust the heat generation opening by adjusting the wick height by raising or lowering the wick height. As shown in Figure 2, it is now possible to make the stove larger than conventional stoves. Furthermore, the third
As shown in the figure, the height between the inner and outer flame tubes 1.2 is ±2 jn
It is possible to maintain this characteristic if it is about m.

In addition, the flame formed here has a rather small excess air ratio in the part where the wick is high because there are many vaporized parts, and in order to send thick air to the flame part, yellow flame combustion is performed and the wick height is lowered. Then, the excess air ratio increases, resulting in blue flame combustion, and the user can visually see the change in the heat generation temperature. Still, in the configuration of this embodiment as shown in FIG.
Since it is located at the upper end of the interior of the incandescent body, it must flow inside the incandescent body, which has the advantage of sufficiently emitting incandescent heat and increasing the fusion efficiency.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) Since air is supplied from the inside and outside in a concentrated manner to the flame forming part, complete combustion can be achieved and less C○ etc. are generated.

(2) Since exhaust gas characteristics can be cleared in response to changes in wick height, a wide combustion adjustment range can be achieved.

(31) Since it is possible to form a long flame, it is possible to create a high-load combustion cylinder that can generate heat even if the shape is small.
