に拡張しうる効果がある。Therefore, it is possible to simplify the installation of the heat exchange duplex 19 to the duplex burner and reduce the number of installation steps, and it is also possible to expand the effective surface area of one heat exchange tube and greatly expand the heat transfer area, for example. Compared to a conventional heat exchanger in which the air flow rate and flow path length are the same, this has the effect of expanding the heat transfer area to approximately two or more areas.

効果がある。Therefore, the heat of the exhaust gas can be effectively conducted to the heat exchange tube 19, and the combustion air flowing inside the heat exchange tube 19 can be effectively heated to increase the heating temperature of the combustion air. For example, the combustion efficiency of a tube burner at a furnace temperature of 1900℃ is compared to that of a conventional tube burner.
It has the effect of increasing f2 melon from around 0% to 80% under the same FI condition.

る。In addition, since the combustion air heated to a high temperature is fed into the vicinity of the base end of the air supply pipe 5, passes through the swirler 12, and is supplied to the air supply port 5a while swirling, the high temperature air is supplied as a gas. It is possible to distribute the gas evenly around the tip of the tube 7 and send it out, improving the combustion state of the gas and making the temperature distribution inside the inner burner tube 14 uniform. This has the effect of not only improving the durability of the inner tube 14 but also ensuring proper combustion of the gas even if the gas is supplied at a pressure of 11 to the gas supply pipe 7.

ができる。In addition, in this example, the inner burner pipe 14 is supported by the support rod 15, the support ring 16, and the support plate 17 so as to be able to freely move in the axial direction, so that the expansion and contraction behavior caused by the expansion and deformation of the inner barb pipe 14 is absorbed. Thus, the supporting state of the inner burner tube 14 can be stabilized.
