Description
Technical Field
[0001] This utility model relates to the field of burner technology, and in particular to a long-tube air-cooled burner. Background Technology
[0002] Long-tube air-cooled burners are combustion devices commonly used in industrial heating equipment. Their core features are high-efficiency combustion and safe operation achieved through a long-tube structure and air cooling. They are typically long and thin metal tubes with fuel nozzles and air mixing devices inside or at the ends. Fuel and air are fully mixed inside the tube or near the tube opening before combustion, and the flame is stably output along the direction of the tube. Air ducts are designed on the outside or around the long tube, and cold air is forcibly introduced by a fan and flows over the surface of the tube. The air flow carries away the excess heat generated by combustion, preventing the tube from being damaged by overheating.
[0003] However, most existing burners are installed in the required positions via flanges during use. Over time, the vibration caused by combustion can lead to the burner tube shaking, affecting the safety of the burner. Therefore, a long-tube air-cooled burner is needed to solve the above problems.

These support rings 9 are symmetrically distributed on both sides of the mounting flange 6. An adjusting slide rod 10 is slidably connected in the middle of the support ring 9. The adjusting slide rod 10 passes through the support ring 9. There are four adjusting slide rods 10, which are symmetrically distributed on the upper and lower sides of the mounting flange 6. One end of the adjusting slide rod 10 is provided with a threaded groove. The adjusting slide rod 10 is connected to an adjusting nut 11 through the threaded groove. The adjusting nut 11 is located on the side of the mounting flange 6 closest to the mounting side plate 5. Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a limiting slider 12 is fixedly connected to the end of the adjusting slide rod 10 away from the adjusting nut 11.
