As is clear from Table 1 above, in the combustion cylinder structure provided with the outer flame cylinder top ring 19 of this embodiment, the exhaust gas after primary combustion is regenerated by this outer flame cylinder top ring 19. Since it can be burned (secondary combustion), the carbon monoxide concentration (CO value) in the exhaust gas can be greatly reduced compared to the conventional product that does not have the outer flame tube top ring 19 at all. The cleanliness (purification degree) of can be greatly improved. Although the secondary air circulation hole of the conventional product has a hole area of about 302 mm 2 , the outer flame tube top ring 1
Since it does not have 9, the exhaust gas purification rate is poor.

As described above, since the cylindrical secondary combustion promoting means (see the external flame tube top ring 19) having the predetermined height H is arranged above the pressing member (see the glass pressing member 18), This secondary combustion promoting means (outer flame tube top ring 19
The exhaust gas after the primary combustion can be re-combusted (secondary combustion) by the reference), and as a result, the carbon monoxide concentration in the exhaust gas, that is, the value of CO, can be significantly reduced, and exhaust gas purification (cleanliness (Improvement) can be achieved.

Further, by forming the above-mentioned secondary combustion promoting means (see the external flame cylinder top ring 19) into a non-perforated cylindrical shape having no hole (ventilation hole) in the cylinder wall, Simply by additionally arranging the secondary combustion promoting means (see external flame tube top ring 19) of a simple structure to the existing chimney structure while preventing the excess air from flowing into the cylinder from the outer circumferential direction of the cylinder. The above effects can be obtained.

Further, the mounting surface 18a of the holding member (see the glass holding member 18) on which the above-mentioned secondary combustion promoting means (see the outer flame tube top ring 19) is arranged is formed in a non-hole shape (see Table 1). Since the pressing member (see the glass pressing member 18) for the mounting surface 18a of this pressing member (see the glass pressing member 18) is omitted, the man-hours and costs for manufacturing the glass pressing member 18 can be reduced, and the pressing member 18 can be reduced. It is possible to re-combust by the above-mentioned secondary combustion promoting means (see the outer flame cylinder top ring 19) and to significantly reduce the carbon monoxide concentration in the exhaust gas while ensuring the mechanical strength and rigidity of effective.
