本発明は液体燃料用燃焼器に用いられる燃焼芯
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combustion wick used in a liquid fuel combustor.
液体燃料を燃焼芯の毛細管現象によつて吸上

燃料の一部が酸化，重合反応等によつてタール状

ル状物質の生成，蓄積は著しく増大する。 The so-called wick vaporization type sucks up liquid fuel by the capillary phenomenon of the combustion wick, and vaporizes and burns the liquid fuel from the tip of the combustion wick exposed in the vaporization chamber, that is, the surface of the fuel vaporization section. Combustors are widely used in oil stoves, oil stoves, and the like. 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 are mixed into the fuel (for example, when machine oil, diesel oil, salad oil, etc. are mixed into kerosene), or if some of the fuel components are deteriorated (for example, if kerosene is left at high temperatures or under direct sunlight for a long period of time) (oxidants, peroxides, resins, etc.) that are generated during storage, the generation and accumulation of the tar-like substances increases significantly.
このタール状物質が燃料気化部に蓄積した時、
燃料気化部の表面あるいは内部の毛細管が閉塞さ
れ、燃料の吸上げや気化が阻害される。このため
燃料気化量が異常に低下し、燃焼室における空燃

これを支持する金属部とを固着させ、燃焼芯の機
械的動作を不可能ならしめ、燃焼芯を下げての消
火操作を不能とする様な危険な状態もあつた。 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, causing problems such as the air-fuel ratio in the combustion chamber being disrupted and the generation of odor, soot, and harmful 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, during which time the unstable transient combustion causes odor and soot. , and increased the generation of carbon monoxide, etc. Furthermore, there are dangerous situations in which the tar-like substance adheres to the combustion wick and the metal parts that support it, making it impossible for the combustion wick to operate mechanically, making it impossible to extinguish the fire by lowering the combustion wick. Ta.
本発明はこのような従来の欠点を解消するため
に、タール状物質の生成蓄積を抑制することを目
的とするものである。 The present invention aims to suppress the generation and accumulation of tar-like substances in order to eliminate such conventional drawbacks.
この目的を達成するために本発明は、セラミツ

部内部に浸透させるとともに気化部表面の毛細管
径を小にしたものである。 In order to achieve this object, the present invention provides that the blending ratio of silicic anhydride and inorganic pigment is 100% of silicic anhydride in at least a part of the combustion vaporized part of a porous body formed by adding a small amount of organic binder to ceramic fibers. On the other hand, it is impregnated with a paint consisting of silicic anhydride, an inorganic pigment, and a surfactant with an inorganic pigment content of 15 to 300%, which penetrates into the vaporization part and reduces the capillary diameter on the vaporization part surface.
この構成によつて、燃料気化部の毛細管径が小

タール状物質の生成蓄積が抑えられ、長期間安定
な燃焼を維持し得ることとなる。 With this configuration, the capillary diameter of the fuel vaporization section is reduced, and because the inorganic pigment is dispersed in the fuel vaporization section, high boiling point components and degraded components, which are the main causes of generation and accumulation of tar-like substances, are removed. However, the fuel is easily pushed out to the surface of the fuel vaporizing section, which is in a high temperature state due to capillary phenomenon, and the fuel is easily decomposed and vaporized by the catalytic action of inorganic pigments at high temperatures, which causes the fuel vaporization of the combustion wick to be delayed. The generation and accumulation of tar-like substances in the combustion chamber is suppressed, and stable combustion can be maintained for a long period of time.

易くなる。 That is, fuel F (solid arrow) is sucked up within the main core 1 and vaporized from the surface of the fuel vaporization section 4. At this time, in the conventional example, as shown in Fig. 2, the temperature of the fuel vaporization section 4 is high (around 150°C) during steady combustion.
Therefore, the fuel is not drawn up to the surface of the fuel vaporizing section 4 due to capillary action. For this reason, the fuel is easily vaporized from inside the fuel vaporization section 4, and the high boiling point components and deterioration components (white arrows), which are the main factors in the formation and accumulation of tar-like substances, are not sucked up to the surface of the fuel vaporization section 4. 4.Accumulated inside the body, turned into a tar-like substance, and accumulated. Furthermore, as shown in Figure 3, even when the blending ratio of silicic anhydride and inorganic pigment 5 is 5.10 to 100 silicic anhydride, there is no particular difference from the conventional example, such as high boiling point components and deterioration components. was accumulated inside the fuel vaporization section 4 and turned into a tar-like substance.
However, as shown in FIG. 4, the blending ratio of silicic anhydride and inorganic pigment 5 shown in this example is
When the ratio of the inorganic pigment 5 to 100 parts of silicic anhydride is 100 parts, the surface of the fuel vaporization part 4 is blocked to some extent by the inorganic pigments 5, and the capillary diameter becomes small. Therefore, even during steady combustion, the fuel is
The fuel is sucked up to the surface by capillary action, and along with this, high boiling point components and degraded components are also catalyzed by the inorganic pigment 5 that has penetrated into the fuel vaporization section 4, and the capillary diameter is reduced. Therefore, even if the fuel is in a high temperature state, the fuel permeates sufficiently and is sucked up and pushed out together with the fuel to the surface of the fuel vaporization section 4 where it is sucked up. As a result, high boiling point components and degraded components are decomposed and vaporized in the inorganic pigment 5 that acts as an oxidation catalyst on the surface which is hotter than the inside of the vaporizer (approximately 180°C during combustion), and become tarry. No formation or accumulation of substances such as However, as shown in FIG. 5, when the blending ratio of silicic anhydride and inorganic pigment 5 is 100 parts of silicic acid anhydride and 400 parts of inorganic pigment 5, the surface of the fuel vaporization part 4 is blocked by the inorganic pigment 5. As a result, the vaporization of the fuel is suppressed, and high boiling point components and degraded components are also not vaporized and are likely to accumulate as tar-like substances.

がわかる。 Incidentally, Figure 6 shows the results of combustion using a suction vaporization type oil combustor. The fuel used was a mixture of white kerosene and salad oil at 0.1% by volume, and when comparing the effect on the reduction in calorific value depending on the blending ratio of silicic anhydride and inorganic pigment 5, it was found that silicic anhydride 100% inorganic pigment It can be seen that when the temperature is between 15 and 300, the calorific value maintenance characteristics are extremely good.

わたる安定燃焼を維持できる。 As described above, the combustion wick of the present invention has a porous body formed by adding a small amount of an organic binder to ceramic fibers, and at least a portion of the fuel vaporization part thereof is impregnated with a paint consisting of an inorganic pigment, silicic acid anhydride, and a surfactant. ,
By setting the blending ratio of the inorganic pigment and silicic anhydride to 15 to 300 parts of the inorganic pigment to 100 parts of the silicic anhydride, the generation and accumulation of tar-like substances can be suppressed and stable combustion can be maintained over a long period of time.

制できる。 In addition, since the inorganic pigment that has penetrated into the fuel vaporization part acts as a catalyst and the capillary diameter is small, high boiling point components and degraded components in the fuel can reach the high temperature vaporization part surface. Precipitation and vaporization proceed smoothly, and tar formation can be significantly suppressed.
