An embodiment of the present invention will be described with reference to the drawings.
In the drawing, reference numeral 1 denotes a combustor main body, and the combustor main body 1 has a combustion tube 5 made of glass having a cylindrical cross section interposed between a burner 2 and an upper member 4 connected to an exhaust tube 3. Burner 2
A connecting portion where the upper member 4 and the combustion tube 5 made of glass are connected to each other is provided with a packing insertion groove 6, and a packing 7 is inserted into each of the packing insertion grooves 6, and The burner 2 and the lower end of the glass-made combustion tube 5 and the upper end of the glass-made combustion tube 5 and the upper member 4 are sealed.

To explain this further, the burner 2 is composed of a pot burner 2a having a large number of air holes 2a-1 formed in several steps around the outer cylinder 2c so that an air chamber 2b is formed around the pot burner 2a. And a blower 2d is provided in the air chamber 2b.
And forcibly supplies air to the air chamber 2b, and burns the pot burner 2a while supplying kerosene from an oil supply pipe (not shown). An annular packing insertion groove 6 was provided between upper ends of the outer cylinder 2c and the pot burner 2a. The upper member 4 is a heat exchanger 4a connected to the exhaust stack 3.
A cylindrical portion 4b connected to the upper end of the glass combustion tube 5 is provided at the lower center of the cylinder, and a packing insertion groove 6 is provided annularly at the lower end of the cylindrical portion 4b. In the embodiment shown in FIGS. 1 to 3, the packing 7 inserted into both the packing insertion grooves 6 is applied so as to divide the non-woven fabric 7 a made of heat and fire resistant ceramics or the like into and out of the non-woven fabric 7 a. It consisted of a metal foil 7b.

To explain this further, as shown in FIG. 3, the packing 7 is formed by attaching a metal foil 7b such as an aluminum foil to one side of a heat-resistant and fire-resistant non-woven fabric 7a such as a ceramic fiber.
After a cut a was made in the center of the opposite side, it was bent so that the side where the metal foil 7b was pasted overlapped as shown by a two-dot chain line in FIG. 3, and this was inserted along the packing insertion groove 6. To wear. At this time, the packing 7 is obtained by dividing the nonwoven fabric 7a into and out of the metal foil 7b. The upper and lower ends of the glass-made combustion tube 5 are sealed by the packing 7 by being inserted to an appropriate position between the metal foils 7b, 7b. In this case, sealing can be performed without applying stress to the glass combustion tube 5 and without exhaust gas leaking from the packing 7.

FIG. 4 shows another embodiment. In this embodiment, a packing 7 is made of a heat-resistant and fire-resistant non-woven fabric 7a such as ceramic fiber and the packing insertion groove 6 of the non-woven fabric 7a.
The metal foil 7b was formed on the surface exposed from the substrate.

In this case, the nonwoven fabric 7a was previously formed in a shape having a groove into which the glass combustion tube 5 was inserted, and a metal foil 7b was applied along the groove.

In this case, the glass combustion tube 5 can be sealed without stress and without leakage of the exhaust gas from the packing 7.

In the drawing, reference numeral 8 denotes a red-hot cylinder facing the glass combustion cylinder 5 and 9 denotes an outer frame for accommodating the combustor body 1.

[0015]

According to the first aspect of the present invention, there is provided a sealing device for a combustion tube for a heating machine having the above-mentioned structure, wherein the packing is formed by dividing a heat-resistant and fire-resistant nonwoven fabric such as a ceramic fiber into and out of the nonwoven fabric. With the configuration, the non-woven fabric forming the packing is divided inside and outside by the metal foil,
Exhaust gas cannot pass through the metal foil portion to prevent the exhaust gas from leaking to the outside, and it is extremely simple to apply a metal foil to the heat-resistant and fire-resistant nonwoven fabric so as to cut the inside and the outside. Problems such as an unpleasant smell filling the room can be eliminated.

According to the second aspect of the present invention, there is provided a sealing device for a combustion tube for a heater, wherein the packing is provided on a surface of the non-woven fabric such as a ceramic fiber which is heat-resistant and fire-resistant and exposed from the groove of the non-woven fabric. The exhaust gas can be prevented from leaking outside through the nonwoven fabric, and it is extremely simple to apply a metal foil to the heat and fire resistant nonwoven fabric so as to divide the exhaust gas into and out of the nonwoven fabric. Troubles such as the room being filled can be eliminated.
