Wherein, the number of the second fire holes 22 is larger than that of the first fire holes 12, and the diameter of the second fire holes 22 is smaller than that of the first fire holes 12. The first fire holes 12 and the second fire holes 22 form two layers of fire holes, so that the adjustable fire range of the fire cover is enlarged. Specifically, in the low fire state, the gas is combusted through the second fire holes 22 with relatively small diameters and relatively large number, and the intensity of the fire holes is low, so that the backfire is avoided in the minimum fire state; in a big fire state, the high-speed flowing gas generates flame separation relative to the second fire holes 22 and is collected to the first fire holes 12 with higher fire hole strength for burning; the minimum value of the fire hole intensity is determined by the size of the second fire hole 22, the maximum value of the fire hole intensity is determined by the size of the first fire hole 12, and the fire adjustable range of the fire cover is obviously improved compared with that of a single-layer fire hole, so that the fire adaptability under different fire conditions is fully met.
The sealing structure of the boss 21 or the sealing ring 4 can be selectively arranged according to the structure of the fire cover and the design requirement of the air supply channel 3. For example, the first fire hole 12 located at the center of the first cover plate 1, a boss sealing structure may also be used; the third fire holes 13 located in the circumferential direction of the first cover plate 1 may also use a sealing structure of a sealing ring.
