Description

Technical Field

[0001] This utility model relates to the field of combustion equipment technology, specifically to a low-NOx high-speed burner that is easy to install. Background Technology

[0002] The burner is the core component of combustion equipment, belonging to the terminology of metallurgical engineering. It is mainly used for fuel ignition and flame stabilization and is commonly found in boiler systems in the steel industry. This device achieves mixed combustion by adjusting the flow rate of gas and air. It is adaptable to blast furnace gas and coke oven mixed fuels. Its working stability directly affects the boiler's operating efficiency, energy consumption control, safety and environmental protection indicators. Low-NOx high-speed burners are a type of combustion equipment that reduces nitrogen oxide emissions by optimizing the combustion process and are widely used in industrial boilers, kilns and other scenarios.

[0003] Low-NOx high-speed burners are an essential component of combustion furnaces. To meet environmental protection requirements, reduce nitrogen oxide emissions, improve combustion efficiency, and adapt to high-temperature conditions, low-NOx high-speed burners are necessary. A search revealed Chinese patent CN222597720U, which discloses a high-speed low-NOx burner comprising an air shell, a gas pipe, a burner head, and a burner nozzle. The gas pipe is located at the center of the air shell, with its inlet extending outside the air shell. The burner head is located at the outlet of the gas pipe, and the burner nozzle is located on the side of the air shell near the burner head. The nozzle has an outlet at the end away from the air shell. An inner cavity is opened inside the burner nozzle, and the burner head is located inside the inner cavity. The burner head can mix the fuel gas with a small amount of air to create an oxygen-deficient state. Incomplete combustion occurs in the oxygen-deficient state, which can reduce the combustion temperature and reduce NOx production. The incomplete combustion gas enters the inner cavity through the outlet and mixes with the excess air in the inner cavity for combustion. The mixed gas can be sent into the furnace for combustion, which can convert CO into CO2. Only a combination of three simple structures is needed to achieve efficient and reliable reduction of NOx and CO production during burner combustion.

[0004] The existing technical solutions mentioned above have the following drawbacks: In the process of using the low-NOx high-speed burner, it is mostly installed and fixed by bolts. The installation process is cumbersome, which not only increases the user's installation time and cost, but also causes the bolts to be damaged or stripped due to improper operation by the user, resulting in unstable connection of the low-NOx high-speed burner and the phenomenon of the low-NOx high-speed burner detaching from the combustion furnace.

The positioning mechanism 4 has its inner wall fixedly connected to the right side of the burner 2 surface. The positioning mechanism 4 includes a fixing ring 401, the inner wall of which is fixedly connected to the right side of the burner 2 surface. A protrusion 402 is provided on the right side of the fixing ring 401, and the right side of the protrusion 402 is fixedly connected to the right side of the inner wall of the mounting plate 1. The left side of the protrusion 402 extends through to the left side of the fixing ring 401. A positioning block 403 is provided inside the fixing ring 401. The side of the positioning block 403 closest to the protrusion 402 extends through to the inside of the protrusion 402, and the side of the positioning block 403 away from the burner 2 extends to the outside of the fixing ring 401 and is fixedly connected to a ring 404. The inner wall of the ring 404 is slidably connected to the surface of the fixing ring 401. Support component 5, the top of support component 5 is fixedly connected to the left side of the bottom of burner 2.

[0018] refer to Figure 4 The support component 5 includes a fixing block 501. The top of the fixing block 501 is fixedly connected to the left side of the bottom of the burner 2. A bottom block 502 is provided at the bottom of the fixing block 501. A vertical rod 503 is fixedly connected to the front and rear sides of the top of the bottom block 502. The top of the vertical rod 503 extends through the interior of the fixing block 501. A push block 504 is provided at the bottom inside the fixing block 501. The left side of the push block 504 extends through the left side of the fixing block 501. A limit block 505 is fixedly connected to the front and rear sides of the left side of the push block 504. The left side of the limit block 505 extends through the interior of the vertical rod 503.

[0019] As a technical optimization of this utility model, the support component 5 can limit the position of the burner 2 and prevent the burner 2 from tilting due to its weight during use.

[0020] refer to Figure 3 The right side of the fixing ring 401 has a through hole 6 that works with the protrusion 402, and the surface of the protrusion 402 has a positioning hole 7 that works with the positioning block 403.

[0021] As a technical optimization of this utility model, the burner 2 can be positioned by setting the through hole 6 and the positioning hole 7, so as to prevent the burner 2 from falling off the mounting plate 1.

[0022] refer to Figure 3 A spring 8 is fixedly connected to the side of the positioning block 403 away from the protrusion 402. The side of the spring 8 away from the positioning block 403 is fixedly connected to the inner wall of the fixing ring 401. A gasket 9 is fixedly connected to the bottom of the bottom block 502.

[0025] As a technical optimization of this utility model, the position of the ring 404 can be limited by the combined use of the connecting block 10, the locking block 11 and the arc block 12, so as to prevent the ring 404 from rotating when it is not needed.

[0026] refer to Figure 4 The surface of the vertical rod 503 is provided with a limiting groove 14 that works in conjunction with the limiting block 505. A spring piece 15 is fixedly connected to the right side of the push block 504, and the right side of the spring piece 15 contacts the inner wall of the fixing block 501.

[0027] As a technical optimization of this utility model, the position of the vertical rod 503 and the bottom block 502 can be limited by the setting of the limiting groove 14. The setting of the spring piece 15 can facilitate the reset of the push block 504 and the limiting block 505, and at the same time prevent the push block 504 and the limiting block 505 from moving when they do not need to move.

[0028] The working principle and usage process of this utility model are as follows: When in use, the user pushes the push block 504 to the right, causing the limiting block 505 to disengage from the limiting groove 14. The push block 504 moves to the right to compress the spring 15, and then pulls the bottom block 502 upward to disengage it from the mounting plate 1, making it easier for the user to move the burner 2. After that, the user pulls the locking block 11 outward to rotate it outward around the rotating axis, causing the locking block 11 to disengage from the locking hole 13. Then, the user rotates the locking block 11 counterclockwise, causing the connecting block 10, the ring 404, and the positioning block 403 to rotate around the fixing ring 401, causing the positioning block 403 to disengage from the positioning hole 7. The positioning block 403 rotates counterclockwise to compress the spring 8. After that, the user pulls the burner 2 to the left, causing the fixing ring 401 to disengage from the mounting plate 1 and the protrusion 402 to disengage from the through hole 6. At this time, the burner 2 can be disassembled. The operation is reversed during installation to fix the position of the burner 2.

[0029] In summary, this easy-to-install low-NOx high-speed burner uses a positioning mechanism 4 to position the burner 2, preventing it from detaching from the mounting plate 1. Then, the support assembly 5 provides limiting support for the burner 2, preventing it from tilting due to its weight. This solves the problem that most low-NOx high-speed burners are installed and fixed with bolts, a cumbersome process that increases user time and cost. Improper operation can also damage or strip the bolts, leading to unstable connections and the burner detaching from the combustion furnace.
