Therefore, during combustion, some of the fuel components change into tar-like substances due to the high temperature and the presence of oxygen, which accumulates in the fire area and obstructs the supply of fuel to the fire area. The capillary for vaporization of is blocked,
It was either impossible to ignite or heat the fire, or the speed of the fire slowed significantly, producing a large amount of odor, soot, and carbon monoxide.

時、速やかに火まわりする。In order to achieve this object, the present invention has a combustion chamber configured between an inner flame tube and an outer flame tube having a large number of air holes, a main structure in which the upper side of the combustion chamber is exposed, and a fire-related auxiliary wick provided therein; and a shield provided between the main body and the fire-related auxiliary wick through which fuel does not pass, the lower end of the auxiliary wick being positioned above the fuel liquid level during combustion. In addition, air baffle plates are provided that protrude from the outer peripheries of the walls of the inner and outer flame tubes facing the main fuel vaporization section to form a pore flame. With this configuration, the auxiliary wick for the fire surroundings is in a dry firing state during combustion, there is no generation or accumulation of tar-like substances, and even during long-term use, the fire starts quickly when ignited.

さく弱い保炎が形成される。On the other hand, in steady combustion, at the beginning of use, a large amount of air is supplied by the air conditioning plate from the air holes below the air conditioning plate, so a small and weak flame holding is formed on the wall facing the fuel vaporization part despite the high fuel gas concentration. be done.

支障をきたすことも防止できるものである。Next, when tar-like substances are generated and accumulated in the fuel vaporization part due to long-term use, the fuel gas concentration decreases and the temperature of the fuel vaporization part and the surrounding area rises, causing a large and strong pore flame to form. . Most of the combustion heat increased due to the expansion of this pore flame is supplied to the fuel vaporization section to promote vaporization and recover the fuel vaporization amount (combustion amount), and also has the effect of thermally decomposing and removing tar-like substances. , fuel vaporization amount (
This will prevent a decrease in combustion amount). Furthermore, since the tar-like substances are decomposed and removed as described above, an increase in the thickness of the fuel vaporization part and adhesion to metal parts can be avoided, and it is also possible to prevent problems in vertical operation of the wick.

。In the above configuration, when a part of the fire wick 9C is ignited by an ignition heater or the like, the flame quickly moves to the entire length of the fire wick 9C, and at the same time, sequentially promotes the fuel vaporization of the main feature 9b,
The combustion chamber 6 transitions to a stable combustion state. In this combustion state, the lower end of the fire wick 9C is placed above the fuel liquid level as explained in Figure 2, and it is still separated from the main body 9b by the shield 9d, so it is new. There is no fuel supply, and when the fuel contained in the fire wick 8b is completely vaporized, there is no fuel, resulting in a so-called dry firing state. Therefore, during combustion, the fire wick 9C is in a dry state, and there is no accumulation of tar-like substances, and when the fire is extinguished, the lower end of the fire wick 9C is immersed in the fuel, and the fuel is quickly sucked up. Therefore, the above performance hardly changes even after long-term use.
A favorable state can be maintained. On the other hand, in steady combustion, fuel vaporizes from the surface of the main body 9b, but
(b) Since the surface is at a high temperature and comes into contact with oxygen, tar-like substances may be generated and accumulated. Particularly when part of the fuel is oxidized or altered, or when high boiling point components are mixed in, tar-like substances are generated and accumulated, and the capillary tubes on the surface or inside of main body 9b are clogged in a relatively short period of time. . This impairs the vaporization of the fuel, causing the air-fuel ratio to collapse and resulting in incomplete combustion, which causes the generation of odors, soot, carbon oxides, and the like. Therefore, in this embodiment, the sixth
As shown in the figure (m), since the fuel gas concentration near the air hole 32L is sufficiently high and the temperature is low, this is an area in which stomatal flame is normally difficult to form. In this embodiment, since the air baffle plate 1o is provided protruding from the outer periphery of the outer flame tube 3, a large amount of air is supplied from the air hole 3a below the air baffle plate 10, and the fuel gas concentration is high and the temperature is low. Nevertheless, a stable stomatal flame f is formed in the air holes 3&. In the initial stage of use, the pore flame f is formed small and weakly on the inner wall side of the outer flame tube 3 because the fuel gas concentration is sufficiently large, and steady combustion occurs in this state. On the other hand, when the tar-like substance t accumulates in the fuel vaporization section 9a as shown in FIG. Since the gas concentration decreases, a large and strong pore flame f comes to be formed on the side of the fuel vaporization section 9a. A slight decrease in the amount of fuel vaporization easily causes the expansion of the pore flame f, and the expansion of the pore flame f matches the degree of decrease in the amount of fuel vaporization.

ても上記の効果を十分発揮することができる。Since this pore flame fFi is located at a position facing the fuel vaporization section 9a, most of the combustion heat increased due to the expansion of the pore flame f is given to the fuel vaporization section 91L without being lost to other heat sources, promoting vaporization and increasing the amount of fuel vaporization. In addition to recovery, the accumulated tar-like substance t is also thermally decomposed and removed, thereby preventing a decrease in the amount of fuel vaporized. In this way, the pore flame f of the air hole 3a is expanded toward the fuel vaporizer 9a side in accordance with the amount of tar-like substance generated in the fuel vaporizer 91L, suppressing a decrease in the amount of fuel vaporizer, and
The tar-like substance t is decomposed and removed, and good combustion without producing odor, soot, carbon monoxide, etc. can be maintained for a long period of time. Note that the above-mentioned effects can be sufficiently exerted even when the air regulating plate 10 projects downward in an open angle shape or when it projects downward in a bent manner.

Figure 6 shows the effect of combustion using 1 volume of humid kerosene. In the conventional model (solid line B), the calorific value (kcal, 4) decreased to 70% of the rated value in about 10 hours, and the amount of carbon oxide and odor generated increased, but in the inventive model (solid line B), Even after 100 hours of combustion, the calorific value was still higher than the rated value of 9e, and almost no carbon oxide or odor was observed.

よい。Further, in the above configuration, since the tar-like substance t is decomposed and removed, stable and favorable performance can be maintained without impairing the ignitability and fireability upon ignition. In addition, the thickness of the fuel air large portion 92L, the inner core cylinder 6 and the outer core cylinder 7 are increased.
This also prevents the lamp from sticking to metal parts such as the lamp wick, and prevents the lamp from interfering with the vertical operation of the lamp wick 9. In this embodiment, the air baffle plate 10 is provided projecting from the outer periphery of the outer flame cylinder 3 with the main body 9b facing outside and the fire wick 9C facing inside, but the reverse may be used.

Defense +1-1 and the odor that follows this,
