[0003] The utility model with publication number CN218174814U discloses a combined quartz tube burner structure and pipe expander, comprising: annular hydrogen main pipe, annular oxygen main pipe, multiple external burners and multiple internal burners, both kinds of annular main pipes are formed by two oppositely arranged arc-shaped gas inlet pipes, the external burners are uniformly distributed on the inner side of the main pipe, and their wick pipes are connected to the hydrogen main pipe, and their lamp housings are connected to the oxygen main pipe, the internal and external burners are coaxially and oppositely arranged, when in use, the butt joint part of the quartz tube is arranged between the internal and external burners, the arc-shaped gas inlet pipes on the left and right sides are synchronously close to the part, the external burners spray flames inward toward the butt joint center, and the internal burners can spray flames outward from the center on the circumference, and form a counter-spraying form with the annular inwardly sprayed flames, at the same time, the distance between the two arc-shaped gas inlet pipes can be flexibly adjusted to adapt to quartz tubes with different diameters, so that the butt joint part is always burned at the highest temperature of the flames, which helps to improve the heating efficiency and prevent the quartz tube from deforming and other quality problems.

[0004] In the prior art, the annular burner mainly has the following problems:

[0005] Firstly, the mainstream quartz material annular burner is difficult to burn, and the burning precision is not easy to control, in addition, due to the low strength of quartz material and poor resistance to rapid temperature change, it is easy to break in actual engineering application. Due to process limitations, the annular burner burned has a large volume, so that the quartz material annular burner is limited in engineering application, especially for applications with very compact volume requirements.

[0006] Secondly, the existing annular burner of metal material is mostly processed by bending pipe welding, which leads to poor precision, large volume, and difficulty in simultaneously meeting the requirements of circulating water cooling and rapid replacement of the flame nozzle, and also has limitations in engineering application.

[0007] Thirdly, the traditional burner has safety hazards in the mixing mode of fuel gas and oxygen. Most traditional annular burners adjust the flow at the gas inlet and mix fuel gas and oxygen, and the mixed gas needs to flow through a long path before burning. The volume of combustible mixed gas stored in the pipeline is large, which makes it easy to appear backfire during ignition or extinguishing process, and has safety hazards.
