[0002] The burner nozzle for heating furnace is a device that mixes gas and air in a certain way and sprays them out for combustion. For heating furnaces used in refining, the main gas is natural gas. Whether the natural gas can be fully burned through the burner depends on the design of the burner, and the key part is the design of the burner nozzle, which directly determines the quality and amount of premixed gas entering the burner, thereby affecting the combustion efficiency and completeness of the gas and the consumption of gas and air.

[0007] Furthermore, the cover body also includes a perforated plate, the perforated plate is connected to the metal fiber mesh, and the perforated plate is located between the metal fiber mesh and the heating cavity.
[0008] Furthermore, the area of the perforated plate is larger than the area of the opening of the combustion plate, and the perforated plate clamps the metal fiber mesh to cover the opening of the combustion plate.
