にある。Detailed Description of the Invention The present invention relates to a combustion wick used in a liquid fuel combustor, and its purpose is to suppress the generation and accumulation of tar-like substances in the fuel vaporization part of the combustion wick and maintain stable combustion for a long period of time. The purpose of the present invention is to provide a combustion wick that can be used.

ール状物質の生成、蓄積は著しく増大する。 A so-called suction vaporization type combustor that sucks up liquid fuel by the capillary action of the combustion wick and vaporizes and burns the liquid fuel from the tip portion exposed in the vaporization chamber of the combustion wick, that is, the surface of the fuel vaporization section. is widely used in oil stoves, oil stoves, etc. In this type of combustor, the fuel vaporization section is exposed to a high temperature and oxygen-containing atmosphere, so some of the fuel contained in the fuel vaporization section is exposed to oxidation, polymerization, etc. during combustion. The phenomenon of turning into a tar-like substance and accumulating it in the fuel vaporizer easily occurred. In particular, if trace amounts of high-boiling components get mixed in during combustion (for example, when machine oil, light oil, salad oil, etc. get mixed into kerosene), or some of the fuel components change (for example, if kerosene is left at high temperatures for a long period of time or exposed to direct sunlight). Store under oxides, peroxides,
If resin, etc. are generated), the generation and accumulation of the tar-like substance increases significantly.

ず、危険な状態に至らせることもあつた。 When this tar-like substance accumulates in the fuel vaporization section,
The capillary tubes on the surface or inside the fuel vaporizing section are blocked, inhibiting fuel suction and vaporization. As a result, the amount of fuel vaporized is abnormally reduced, and as a result, the amount of heat generated is significantly reduced, causing problems such as the air-fuel ratio in the combustion chamber being disrupted and the generation of odor, soot, and toxic carbon monoxide. In addition, at the time of ignition, the tar-like substance prevents a rapid temperature rise in the fuel vaporization section and an increase in the amount of fuel vaporization, and it takes an extremely long time to reach stable combustion. Large amounts of soot, carbon monoxide, etc. were generated. In addition, the tar-like substance can cause the wick to stick to the metal parts that support it, making it impossible for the wick to move mechanically and making it impossible to lower the wick to extinguish the fire, which can lead to a dangerous situation. It was hot.
本発明はこれら従来の欠点を解消するために、

本発明の一実施例を添付図面と共に説明する。 In order to eliminate these conventional drawbacks, the present invention
This invention suppresses the generation and accumulation of tar-like substances, and one embodiment of the present invention will be described below with reference to the accompanying drawings.

は解消される。 FIG. 2 shows a conventional fuel vaporizing section, and FIG. 3 shows an embodiment of the present invention in which the surface of the fuel vaporizing section is covered by 30 to 50% from the tip. That is,
Fuel f (solid arrow) is sucked up inside the main core 1,
The fuel vaporizes from the surface of the fuel vaporizer 3. At this time, in the conventional example, as shown in FIG. 2, a large amount of the fuel f is vaporized from the tip of the fuel vaporizing section 3. However, trace amounts of high-boiling components and degraded components in the fuel do not easily vaporize. For this reason, high boiling point components and altered components accumulate at this tip, which changes into a tar-like substance t (white arrow) under the influence of temperature and oxygen. However,
In the embodiment of the present invention in which 30 to 50% of the fuel vaporization section 3 is covered from the tip, as shown in FIG. 3, the fuel f is vaporized to some extent from the tip of the fuel vaporization section 3; The amount of vaporization is smaller than in the case without it, and the emissivity of the upper part of the vaporization part increases due to the action of the coating material 4, making it more susceptible to the surrounding atmospheric temperature.As a result, heat is accumulated and the tip of this vaporization part Temperature rises. Therefore, trace amounts of high boiling point components and altered components in the fuel are thermally decomposed at this high temperature tip and easily vaporized. Furthermore, the inorganic pigment and silicic anhydride used as the coating material 4 are a kind of oxidation catalyst, and their catalytic action accelerates this thermal decomposition action. in this way,
In the embodiment of the present invention in which the fuel vaporization section 3 is covered from the tip by 30 to 50%, the surface of the fuel vaporization section 3 does not accumulate tar-like substances t and the surface always maintains porosity, so that the vaporization of the fuel f is prevented. Stable combustion is maintained without being inhibited, and various problems associated with conventional methods are eliminated.
ここで燃料気化部３は先端から10〜20％被覆し
たものにおいては、燃料気化部３先端からの気化

いては、気化面が閉塞されているため気化が不十
分であり、発熱量が少量であるため安定な燃焼を
なし得ない。また、そのためタールも蓄積しやす
くなる。 Here, if the fuel vaporizing section 3 is covered by 10 to 20% from the tip, tar-like substances tend to accumulate because the amount of vaporization from the tip of the fuel vaporizing section 3 cannot be sufficiently suppressed. In addition, in the case of 60 to 90% coating, vaporization is insufficient because the vaporization surface is blocked, and stable combustion cannot be achieved because the calorific value is small. This also makes it easier for tar to accumulate.
ちなみに吸い上げ気化方式の石油燃焼器を用い
て燃焼させた時の結果を示すと第４図の様にな

It can be seen that the decrease in calorific value is significantly reduced compared to the case No. 3 with 10 to 20% coating and the case No. 4 with 60 to 90% coverage.

This prevents the coating material 4 from peeling, cracking, etc., and the effectiveness of the coating material 4 during combustion can be sufficiently maintained.
