Description

[Brief explanation of the drawing]

Fig. 1 is a vertical sectional view showing one embodiment of the combustion device of this invention, Fig. 2 is a similar vertical sectional view showing another embodiment of this invention, and Fig. 3 is a cross section of Fig. 2. The plan view and FIG. 4 are vertical sectional views showing a conventional combustion device. In the figure, 1 is a combustion tube, 1d is an annular wall around the tip, 5 is a vaporization mixing chamber, 6 is a burner plate, 9 is a flame, 11 is a heat insulator, 12 is an annular spring band, 13 is an air groove, and 14 is an outer tube. Shows a shaped wall. In other figures, the same reference numerals indicate the same parts.

Claims (1)

[Claims for Utility Model Registration] (1) A burner plate connected to the vaporization mixing chamber is installed, and the outer circumference of the annular wall at the tip of the combustion tube is heated by the flame generated in the burner plate. A combustion device characterized in that an annular reinforcing body for preventing deformation due to heating is arranged so as to be restrained from the outside. (2) The combustion device according to claim 1, wherein the annular reinforcing body is constituted by a separate annular spring band having a heat insulating material that is press-fitted to the outer peripheral surface of the outer peripheral annular wall at the tip. (3) The combustion system according to claim 1 of the utility model registration, wherein the annular reinforcing body is constituted by an outer cylindrical wall formed integrally with the outer circumferential annular wall at the tip so as to have a large number of air grooves in an annular shape between the annular reinforcing body and the outer circumferential annular wall.
