Description
Technical Field
[0001] This utility model relates to the field of burner technology in the petrochemical industry, specifically to a pre-installed auxiliary combustion chamber burner. Background Technology
[0002] A burner is a general term for a device that sprays out fuel and air in a certain way to mix and burn. Burners are classified into several types according to their application fields, such as industrial burners, combustion engines, civil burners, and special burners. They are mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or titanium. The function of a burner is to atomize the sample through flame combustion.
[0003] Currently, gas burners mainly use air and gas as fuel for combustion. Since air and gas are directly introduced into the pipeline through a fan, uneven mixing of air and gas can easily lead to incomplete combustion and fuel waste. At the same time, because air and gas are directly introduced into the pipeline through a fan, dust easily accumulates inside the pipeline, and residues from the gas also easily adhere to the inner wall of the pipeline. If not cleaned in time, this will affect subsequent ignition operations, requiring improvement. Utility Model Content

[0027] Working principle: When using this pre-installed auxiliary combustion chamber burner, the drive motor 3 first drives the impeller of the fan 2 to rotate, allowing external air to enter through the inner shell 12. As the air enters the inner shell 12, it sequentially contacts the first filter screen 13, the second filter screen 14, and the third filter screen 15, thereby filtering out dust and impurities. The filtered air then enters the auxiliary channel 56 through the outlet of the fan 2. Simultaneously, the fuel gas enters the auxiliary channel 56 through the fuel gas input pipe 4. The air and fuel gas entering the auxiliary channel 56 first enter the mixing channel 55, where they are mixed by the spiral blades 511 before reaching the rear section of the auxiliary channel 56. At this point, the preheating pipe 57 preheats the air and fuel gas. After preheating, the air-fuel mixture is discharged from the right side of the auxiliary channel 56 for subsequent ignition. When the inner wall of the auxiliary channel 56 needs to be cleaned, the first electromagnet 510 and the second electromagnet 512 can be activated to magnetically connect the collar 54 and the mixing channel 55. Then, the rotary motor 51 is started, and when the rotary motor 51 drives the threaded rod 52 to rotate, the screw slide 59 on the outer wall of the threaded rod 52 moves laterally. The screw slide 59 drives the collar 54 and the mixing channel 55 to move synchronously, so that the scraper 53 on the outer wall of the mixing channel 55 scrapes off the residue on the inner wall of the auxiliary channel 56 during the movement. The scraped residue can be cleaned out after the auxiliary channel 56 is separated from the fan 2.
