[0002] Gas burners are gas combustion devices that allow gas and air to enter the combustion zone separately or mixed to achieve stable combustion. Gas includes acetylene, natural gas or propane. Gas burners have been widely used in residential and industrial fields. Closed combustion technology is a comprehensive flue gas treatment technology that converts boiler exhaust gas into air-like gas. Closed gas burners are generally fed by a combustion tube nozzle, so that the combustion tube near the nozzle is in a high temperature environment for a long time.

[0003] The existing devices mainly use high-temperature resistant materials to prepare combustion tubes, which makes it difficult for some devices to effectively cool the combustion tubes in a high-temperature state, resulting in a shorter service life of some combustion tubes. At the same time, it is difficult for some cooling to adjust the retention time of cooling water according to the temperature of the combustion tube, resulting in a lower heat absorption ratio of some cooling water, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a high-temperature resistant combustion tube for a closed gas burner is proposed. Utility Model Content

The first partition 21 and the second partition 23 are alternately arranged. Through this design, cooling water can pass through the first through hole 22 and the second through hole 24 in sequence. A water inlet seat 25 is fixedly connected to the left side of the top of the outer tube 12, and a drain seat 26 is fixedly connected to the right side of the top of the outer tube 12. Through this design, cooling water enters between the inner tube 11 and the outer tube 12, so that the cooling water can absorb the heat of the inner tube 11.

[0024] The adjusting box 16 is provided with an adjusting mechanism 3 inside. The adjusting mechanism 3 includes a transmission worm 31. The left end of the transmission worm 31 is movably connected to the left side of the inner wall of the adjusting box 16. The right end of the transmission worm 31 passes through the adjusting box 16 and is fixedly connected to a twist cover 32. A transmission worm gear 33 is meshedly connected to the upper outer wall of the transmission worm 31. Through this design, the twist cover 32 drives the transmission worm 31 to rotate in a limited position.
