Description
Technical Field
[0001] This utility model relates to the field of boiler burner technology, specifically to a cylindrical high-temperature alloy burner. Background Technology
[0002] A steam boiler, also known as a steam generator, is a device that produces steam. In a steam boiler, the burner is a crucial heating component; its flame heats water, turning it into steam. Currently, most burners used in steam boilers are direct-injection, meaning the length of the burner is aligned with the direction of the flame. However, with technological advancements, more advanced boilers are now coil-tube steam boilers, where the heat exchange coils surround the burner. Using a direct-injection burner would cause the direction of the flame to be inconsistent with the direction of the heat exchange coils, leading to a decrease in the boiler's thermal efficiency. Therefore, there is an urgent need to design a cylindrical high-temperature alloy burner to address these issues. Utility Model Content
[0003] The purpose of this invention is to provide a cylindrical high-temperature alloy burner to address the aforementioned shortcomings in the prior art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A cylindrical high-temperature alloy burner includes an outer cylinder, an inner cylinder inserted inside the outer cylinder, uniformly distributed through holes on the outer wall of the inner cylinder, a metal mesh cylinder welded to the bottom end of the outer cylinder, the bottom end of the inner cylinder extending into the interior of the metal mesh cylinder, and a high-temperature resistant coating on the outer wall of the inner cylinder.
[0006] Furthermore, the metal mesh cylinder includes metal wires, and the outer wall of the metal wires is provided with a high-temperature resistant coating.
[0007] Furthermore, a mounting plate is welded to the top of the outer cylinder, and the bottom outer wall of the mounting plate is provided with evenly distributed mounting holes. The top outer wall of the mounting plate is provided with insertion holes, and the top of the outer cylinder is inserted into the insertion holes.
[0008] Furthermore, an installation ring is welded to the outer wall of the outer cylinder, and a sealing layer is provided on the bottom outer wall of the installation ring. Both the outer walls of the installation ring and the sealing layer are provided with an installation hole.
[0009] Furthermore, the top outer wall of the inner cylinder is provided with a connecting groove, and the inner wall of the outer cylinder is fixed with a connecting column. The connecting column is located inside the connecting groove, and the interior of the connecting groove is integrally formed with a limiting plate that is adapted to the connecting column.
[0010] Furthermore, a sealing plate is welded to the bottom outer wall of the inner cylinder, and an operating rod is welded to the top inner wall of the inner cylinder.
[0011] In the above technical solution, the cylindrical high-temperature alloy burner provided by this utility model has the following advantages: by setting several through holes on the outer wall of the inner cylinder and attaching a metal mesh sleeve to the outside of the inner cylinder, the burner can evenly spray flames in all directions during use, making it more suitable for use in coil-type steam boilers and improving the thermal utilization rate of the coil-type steam boilers; through high-temperature resistant coating one and high-temperature resistant coating two, the burner has a stronger high-temperature resistance during use, thereby improving the service life of the burner; through the setting of the operating rod, connecting groove and connecting column, the inner cylinder can be limited inside the outer cylinder, thereby facilitating the disassembly of the inner cylinder from the inside of the outer cylinder, making the disassembly of the inner cylinder more convenient during maintenance.

Detailed Implementation
[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0021] like Figure 1-5 As shown in the figure, the cylindrical high-temperature alloy burner provided by this utility model includes an outer cylinder 1, an inner cylinder 4 inserted into the inner cylinder 1, and a uniformly distributed through hole 5 on the outer wall of the inner cylinder 4. A metal mesh cylinder 3 is welded to the bottom end of the outer cylinder 1, and the bottom end of the inner cylinder 4 extends into the interior of the metal mesh cylinder 3. A high-temperature resistant coating 13 is provided on the outer wall of the inner cylinder 4.
[0022] Specifically, in this embodiment, an outer cylinder 1 is included, and an inner cylinder 4 is inserted inside the outer cylinder 1. The outer wall of the inner cylinder 4 is provided with uniformly distributed through holes 5. During use, the gas flows out from the inside of the through holes 5. A metal mesh cylinder 3 is welded to the bottom end of the outer cylinder 1. The outer wall of the metal mesh cylinder 3 has several uniformly distributed micropores. The bottom end of the inner cylinder 4 extends into the inside of the metal mesh cylinder 3. The heat exchange coil of the coil-type steam boiler is annular. The burner is located in the annular center of the heat exchange coil. Utilizing the through holes 5 and the micropores on the outer wall of the metal mesh cylinder 3, when the gas flows out from the inside of the burner, it can be evenly sprayed in all directions, thereby enabling the flame to be sprayed and heated to the inner wall of the annular heat exchange coil. The outer wall of the inner cylinder 4 is provided with a high-temperature resistant coating 13. Both the outer cylinder 1 and the inner cylinder 4 are made of high-temperature resistant alloy material.
[0023] The present invention provides a cylindrical high-temperature alloy burner, which, by setting several through holes 5 on the outer wall of the inner cylinder 4 and attaching a metal mesh cylinder 3 to the outside of the inner cylinder 4, allows the burner to spray flames evenly in all directions during use, making it more suitable for use in coil-type steam boilers.
[0024] In another embodiment provided by this utility model, such as Figure 4-5 As shown, the metal mesh cylinder 3 includes metal wires 15, which are woven together. The outer wall of the metal wires 15 is provided with a high-temperature resistant coating 14. The high-temperature resistant coating 14 and the high-temperature resistant coating 13 are preferably molybdenum-chromium alloy coatings. Through the high-temperature resistant coating 13 and the high-temperature resistant coating 14, the burner has a stronger high-temperature resistance during use, thereby improving the service life of the burner.
[0025] In another embodiment provided by this utility model, such as Figure 1-2As shown, an installation plate 9 is welded to the top of the outer cylinder 1. The bottom outer wall of the installation plate 9 is provided with evenly distributed installation holes 10. A fan that mixes gas and air is installed above the installation plate 9. An insertion hole 11 is provided on the top outer wall of the installation plate 9. The top of the outer cylinder 1 is inserted into the insertion hole 11. The insertion of the outer cylinder 1 into the insertion hole 11 improves the sealing during welding. An installation ring 6 is welded to the outer wall of the outer cylinder 1. A sealing layer 7 is provided on the bottom outer wall of the installation ring 6. The sealing layer 7 is made of high-temperature resistant material. Both the outer walls of the installation ring 6 and the sealing layer 7 are provided with installation holes 8. The boiler body is installed at the bottom of the installation ring 6, so that the part below the burner installation ring 6 is installed inside the boiler body.
[0026] In another embodiment provided by this utility model, such as Figure 3 As shown, the top outer wall of the inner cylinder 4 is provided with a connecting groove 16, and the inner wall of the outer cylinder 1 is fixed with a connecting column 17. The connecting column 17 is located inside the connecting groove 16. The connecting groove 16 is integrally formed with a limiting plate 18 that is adapted to the connecting column 17. The limiting plate 18 serves to limit the connecting column 17. The bottom outer wall of the inner cylinder 4 is welded with a sealing plate 2, and the top inner wall of the inner cylinder 4 is welded with an operating rod 12. Through the operating rod 12, the connecting groove 16 and the connecting column 17, the inner cylinder 4 can be limited inside the outer cylinder 1, which makes it easier to disassemble the inner cylinder 4 from the inside of the outer cylinder 1, making the disassembly of the inner cylinder 4 more convenient during maintenance.
[0027] Working principle: When it is necessary to remove the inner cylinder 4 for maintenance, the inner cylinder 4 is pulled upward inside the outer cylinder 1 by operating lever 12, and then the inner cylinder 4 is rotated so that the connecting column 17 is disengaged from the connecting groove. Then the inner cylinder 4 can be pushed downward inside the outer cylinder 1 to remove the inner cylinder 4 from the inside of the outer cylinder 1.
[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
