An air distribution plate 123 is provided at a central position in the gas chamber 120, and air distribution holes 1230 are evenly distributed on the air distribution plate 123, so that the gas can enter the outer annular portion 12 evenly, which can make the gas burn more evenly to a certain extent, thereby achieving the purpose of improving the combustion efficiency of the outer fire cover 1.

[0033] Furthermore, the inner edges of the gas distribution plate 123 and the outer bottom plate 122 are extended inward, and the central part 11 and the connecting part 13 of the outer fire cover 1 are formed by the gas distribution plate 123 and the outer bottom plate 122. The structure is simple and the design is reasonable. Therefore, the burner provided in this embodiment can be manufactured and produced by using stainless steel plates.

[0034] Preferably, the top surface of the outer top plate 121 is tilted upward from the inside to the outside, and outgoing fire holes 1210 are evenly distributed along the circumference are provided on the top surface of the outer top plate 121. Compared with the existing burner, its combustion efficiency can be improved by at least 5%-10%, which can make the combustion of gas more complete and more efficient.

[0035] More preferably, a high-temperature resistant coating is provided on the surface of the outer fire cover 1 and the inner fire cover 2, thereby improving the stability and safety of the fire cover operation and extending the service life of the fire cover.

[0036] Preferably, the outer fire cover 1 and the inner fire cover 2 are forged from stainless steel plates, which can be made of SUS304, SUS316, SUS201, SUS430, or SUS409L, with a thickness of 3.0 mm. During production, the stainless steel plates are placed on a metal stamping die and operated on a stamping machine. The structure is compact and strong, not easily deformed, and has good working stability and safety. It is easy to assemble, has a long service life, and is low in cost, with a high yield rate and production efficiency.
