However, burners are also major contributors to energy consumption, carbon emissions, and environmental pollution; their efficiency directly affects the effectiveness of energy utilization and environmental protection.

[0003] As a core component of industrial boiler systems, the design of the burner head directly affects the nitrogen oxide emission control effect and combustion efficiency. Currently, mainstream low-NOx burners on the market mainly suffer from the following technical defects:

[0004] Traditional adjustable burners mostly use threaded meshing adjustment or gear and rack transmission structure, which requires mechanical reconfiguration of the burner body. The adjustment process requires disassembling the end cover flange or performing multi-stage transmission operations, which is time-consuming and labor-intensive.

[0005] The burner lacks a height adjustment mechanism, making it impossible to dynamically and coordinately adjust the burner axis with the boiler heating surface for different boiler heights, which is inconvenient to use. Utility Model Content
