のであ−、た。The combustion tube has an inner and outer flame tube and an outer tube on the outside, and the petroleum gas vaporized from the core undergoes thermal decomposition and oxidation reactions while rising through the gap between the inner and outer flame tubes.The combustion tube flows into the gap through a small hole in the outer flame tube. Combustion occurs near the pores due to the air generated. If the pressure balance in this combustion tube is disrupted and some of the gas in the gap comes out to the outside of the outer flame tube, if the small hole is small, the flame in the gap will be pushed outward through the small hole. When a fire is lit, heat is absorbed by the outer flame cylinder and the flame is extinguished, generating a trap /I/ that releases incomplete combustion gas directly to the outside. However, it is known that when the small hole diameter of the outer flame tube is large, combustion can be maintained on the outer surface of the outer flame tube without extinguishing the flame, and the outer flame tube can also be heated from the outside to obtain a good glowing state. (Refer to Japanese Patent Publication No. 57-55083) [Problem to be solved by this invention] In this combustion state, the high molecular weight hydrogen ash gas that should rise in the gap between the inner and outer flame tubes flows between the outer flame tube and the outer tube. When this hydrogen ash gas comes out into the gap, it may not be able to be completely combusted by combustion only through the small holes, and there is a risk that it will be discharged as is in an unburned state. Therefore, it is necessary to mix this unburned ganu with air and supply it again to the combustion flame of the fish meat between the inner and outer combustion bodies at the upper part of the outer flame cylinder for complete combustion. For this reason, in the past, it was necessary to use the entire fish meat between the inner and outer combustion bodies to perform combustion in such a way that a flame was formed above the gap, and combustion with the flame height lower than that of the outer flame cylinder resulted in incompletely combusted gas. 9. It was difficult to remove the combustion amount by moving the wick up and down.

。7 is attached to the upper end of the outer flame tube 2, and the inner edge is the inner and outer flame tubes 1 and 2.
This is an outer flame cylinder top plate located above the gap and whose outer edge holds the upper end of the heat-resistant heat transmitting cylinder 3. The combustion tube of the embodiment forms a secondary combustion chamber above a double-tube type combustion part, and constitutes a reburner by expansion combustion, and 8 is mounted on the outer edge of the outer flame tube top plate 7,
The flame tube 9 that constitutes the wall of the secondary combustion chamber is a flame expansion device installed at the tip of the flame expansion tube 11 attached to the upper part of the inner flame section top plate 10, and the gap between the outer flame tube 2 and the outer tube 3 is The air flows in from the small hole at the upper end of the outer flame tube 2 and rises inside the inner flame tube 1.
White-yellow flame combustion is performed by static electricity flowing from the flame spreader 9.

熱分解と酸化反応を行ないながら上昇し、二次燃焼室内
の拡炎装置によって完全燃焼するものである。This invention, which has a partial configuration, performs combustion almost in the same way as a conventional combustion tube, and the oil gas in the gap between the first and second combustion tubes rises while performing thermal decomposition and oxidation reactions, and enters the secondary combustion chamber. Complete combustion is achieved using a flame spreader.
ところで、上記燃焼中に芯下げ操作によって芯からの気

になる。By the way, when the amount of vaporization from the wick is reduced by the wick lowering operation during the combustion, the flame formed in the secondary combustion chamber becomes smaller and eventually comes to be located within the gap between the inner and outer flame tubes 1 and 20.

ない原因となっていた。Conventionally, a receiving portion extending to the outer flame tube 2 was attached within the gap between the outer cylinder 3 and the outer flame tube 2, as shown in FIG. The size of the gap between the tip of the receiving portion and the outer flame tube 2 is set in relation to the amount of heat generated by the combustor, and static electricity passing through this gap is drawn into the surface of the receiving portion. For this reason, the static electricity above the receiving part will be diffused throughout the gap, and due to this empty circulation, the gas in the gap between the inner and outer flame tubes 1 and 2 will easily leak to the outside of the outer flame tube 2. By enlarging the small holes, combustion can now take place outside the outer flame tube 2. However, the combustion gas generated during combustion on the outer surface of the outer flame cylinder spreads throughout the gap due to the airflow that is drawn into the upper surface of the receiving part and the airflow that diffuses throughout the gap, so it is not possible to widen the combustion amount during adjustment. It was the cause.

ようになった。In this invention, the tip of the receiving part 4 facing the outer flame tube 2 is bent upward to form the cylindrical part 5, and the cylindrical part 5 and r#
An air hole 6 is formed in the receiving part 4 between the thermal heat transmitting cylinder 3', and the air flow rising through the gap between the inner edge of the receiving part 4 and the outer flame cylinder 2 continues to flow at a high velocity into the cylindrical part 5. The combustion gas generated during combustion on the outer surface of the outer flame tube also began to flow upward. In addition, the air sword that has flowed into the gap between the cylindrical part 5 and the heat-resistant heat transmitting cylinder 3 from the air hole 6 also rises, and the cylindrical part 5
Since the combustion gas rises smoothly without creating turbulence at the tip of the cylinder, the combustion gas is difficult to diffuse due to static electricity rising on the inner wall of the heat-resistant heat-transmitting tube 3#, and a state of low combustion gas can be maintained. It became so.

。For this reason, when the wick is raised, combustion is carried out by the airflow rising through the entire gap, and when the wick is lowered, the air that does not contain combustion gas near the heat-resistant heat-transmitting tube 3' flows into the outer flame tube 2. It can now pass upward through the small hole in the second part. Experiments have shown that in a conventional product in which the inner edge of the receiving part 3 is located approximately at the center of the gap, the carbon dioxide concentration in the combustion exhaust gas is reduced to 2°6 when the wick is lowered.
%, the amount of carbon monoxide emitted was 98 PPM, but in a combustion tube with a cylindrical part on the inner edge and an air hole 6 in the receiving part 4, the wick was lowered and the carbon monoxide in the combustion exhaust gas was lowered. The amount of carbon monoxide emitted when the gas concentration is 2.6% is 52 PPM.
It was confirmed that the combustion condition was improved when the wick was lowered.
以上のようにこの発明では耐熱性熱透過筒３を載架する
受け部４の内縁に上方へ折曲げた筒状部５を形成し、か
つ受け部４に空気孔６をあける極めて簡単な構造の追加
によって、芯下げ時の燃焼状態は格段に向上させること
ができたものである。As described above, the present invention has an extremely simple structure in which an upwardly bent cylindrical part 5 is formed on the inner edge of the receiving part 4 on which the heat-resistant heat transmitting cylinder 3 is mounted, and an air hole 6 is formed in the receiving part 4. By adding this, we were able to significantly improve the combustion condition during core lowering.

範囲を大きくすることができたものである。For this reason, in the past, it was not possible to lower the wick until the red-hot outer flame tube 2 became dark and burn it, but with this invention (1♂ζ construction makes this possible, and the combustion amount adjustment range of the combustion tube is It was possible to increase the .
