[0002] The boiler nozzle is an important part of the boiler system, which is used to spray fuel (such as natural gas, oil, etc.) into the furnace in an atomized state to ensure sufficient combustion and heat release;

[0003] In a boiler system, if the boiler nozzle is not easy to replace, the difficult-to-replace nozzle may lead to untimely regular inspections, increasing the safety risks caused by equipment aging or failure. At the same time, the process of replacing and repairing the nozzle becomes cumbersome and complicated, increasing the maintenance time and labor costs. Furthermore, since the process of replacing the nozzle requires more time, the boiler downtime will increase accordingly, thereby affecting the overall production efficiency. At the same time, the nozzle that is not easy to replace may limit the boiler's ability to adapt to different fuels or usage conditions, affecting the flexibility of the system.

[0004] Therefore, we hope to design a boiler nozzle with a local structure that is easy to replace to solve this problem. Summary of the invention
