のCOを発生し始めるという問題があつた。Conventional structure and its problems In general, this type of combustion tube has an inner flame tube 1 and an outer flame tube 2 each having a large number of pores 1a and 2a, as shown in FIG.
An outer cylinder 3 covering the outer lower part of the outer flame cylinder 2 and a heat transmitting cylinder 4 provided on the upper part of the outer cylinder 3 so as to cover the outside of the outer flame cylinder 2 are arranged concentrically. be. As shown in FIG. 4, between the outer cylinder 3 and the heat transmitting cylinder 4, the amount of air flowing into the space 5 between the inner and outer flame cylinders and between the outer flame cylinder 2 and the heat transmitting cylinder 4 is regulated. A regulating ring 7 is provided, and the pores 2a' of the outer flame tube 2 below the air regulating ring 7 are formed almost uniformly to the lower end of the outer flame tube. For this reason, there was a problem in that when the oxygen concentration in the room decreased (hereinafter referred to as an oxygen-deficient state), a large amount of CO began to be generated.

生する。 In other words, under normal conditions other than an oxygen-deficient state, combustion takes place well in the portion between the inner and outer flame tubes 5 that faces the heat transmission tube 4, and the draft between the inner and outer flame tubes 5 is generated between the outer flame tube 2 and the heat transmission tube 4. Sufficiently larger than the draft of 6,
As a result, the air flowing in from the lower part of the outer cylinder 3 enters between the inner and outer flame cylinders 5 through the pores 2a' as shown by the broken line arrow, mixes with the petroleum vapor evaporated from the wick 8, forms a flame-holding state in the pores 2a', and the wick 8 Continue to burn some of the oil vapor that becomes more vaporized. However, when there is a lack of oxygen, internal
The combustion in the portion of the outer flame tube 5 facing the heat transmission tube 4 gradually shifts downward and begins to decrease, and the draft thereof becomes extremely weak compared to the normal state. As a result, the air that was drawn by the draft between the inner and outer flame tubes 5 and flowing as shown by the broken line is now transferred to the air between the air regulation ring 7 and the outer flame tube 2, which has less resistance than the air holes 2a'.
It begins to rise as shown by the solid arrow through the pores 2 and 2.
The amount of air flowing into the space between the inner and outer flame cylinders 5 from a' becomes extremely small. Therefore, the petroleum vapor evaporated from the lamp wick 8 cannot be combusted, the flame holding that had been formed in the pores 2a disappears, and all the petroleum vapor evaporated from the lamp wick 8 rises without being combusted. become. Moreover, between the inner and outer flame tubes 5
Since the combustion power at the portion facing the heat transmission tube 4 is reduced, a portion of the oil vapor is released outside the combustion tube without being completely combusted, and a large amount of CO is generated.

The same parts as the conventional example will be given the same numbers and the explanation will be omitted, and only the different parts will be explained. Among the pores 2a' below the air regulation ring 7, the pores 2a'' near the air regulation ring 7 are set to have a larger opening area than the pores 2a further below. The opening area of the pores 1a'' on the side closer to the air adjustment plate 9 of the inner flame cylinder 1 below the air adjustment plate 9 is made larger than that of the pores 1a below it.

る。 Therefore, with this configuration, even if the draft between the inner and outer flame cylinders 5 becomes weaker than normal due to oxygen deficiency, the air holes 2 near the air regulation ring
Since the opening area of a'' is large, even with the weak draft mentioned above, air can sufficiently flow into the space between the inner and outer flame cylinders 5 as shown by the arrow.
It mixes with petroleum vapor evaporated from the lamp wick 8 and continues to form a flame-holding state in the pores 2a''.In particular, the group of pores 2a'' with a large opening area is provided near the bottom of the air regulation ring 7, so that the outer cylinder 3 The air flowing in from this direction hits this air regulating ring 7 and changes its direction toward the outer flame tube 2 side, so that the above-mentioned air inflow is secured in a sufficient amount to form a flame holding state. Become. Therefore, part of the petroleum vapor that continues to evaporate from the lamp wick 8 is burned in this flame-holding part, so that less unburned petroleum vapor rises, and the inner and outer flame tubes facing the heat transmitting tube 4 are reduced. During the interval 5, the unburned petroleum vapor is almost completely combusted.
特に本実施例では内炎筒側の気孔１a″，１a″に
ついても外炎筒と同様の配慮がしてあるので、前
述した作用は内炎筒側でも行なわれることにな
り、より完全な燃焼が期待できる。 In particular, in this embodiment, the pores 1a'' and 1a'' on the inner flame tube side are given the same consideration as the outer flame tube, so the above-mentioned action is also performed on the inner flame tube side, resulting in more complete combustion. can be expected.
第５図は従来のものに対する本実施例品の排ガ

いずれの方法であつても同様の効果が得られる。 Note that the air hole 2a'' near the air regulation ring of the outer flame tube 2 and the air hole 1 near the air adjustment plate of the inner flame tube 1 are
a'' may be increased by increasing the opening area by increasing the diameter of each pore, or by increasing the pore density while keeping the diameter of each pore the same,
Similar effects can be obtained with either method.

る。Effects of the Invention As described above, the present invention makes the opening area of the pores in the inner flame tube and the outer flame tube below the air regulation ring larger in the area closer to the air regulation ring and smaller in the area below it, thereby deficient in oxygen. Since a stable flame is reliably formed even in the case of oxygen depletion, the amount of CO generated during oxygen deficiency is extremely small, making it highly safe.
