Problems solved by technology

This invention adopts a no-nozzle, fully premixed combustion structure, which can improve the combustion efficiency of the burner and reduce the cost of the burner. However, the structural design of the premixed chamber of the invention is unreasonable, and the open end of the spoiler behind the multi-microporous combustion body The gas pressure is greater than that of the closed end, which makes the gas pressure inconsistent and causes uneven flame, which is easy to produce CO and NOx, which is not conducive to environmental protection

specific Embodiment 1

[0020] Specific embodiment one: as figure 1 As shown, this embodiment includes a burner 1 and a fixing device for installing the burner 1. The periphery of the burner 1 is provided with an air-mixing chamber 3 formed by a casing 2, and between the burner 1 and the casing 2 is a The pressure dividing partition 4 has a gap between the pressure dividing partition 4 and the casing 2 . The pressure dividing partition 4 is a plate-shaped structure with a plurality of small holes distributed thereon. The diameter of the small hole away from the air inlet 7 on the pressure dividing partition 4 is equal to the diameter of the small hole close to the air inlet 7 . The fixing device includes a fixed frame 6 and a fixed plate 5, the fixed frame 6 is a frame structure, the fixed plate 5 is a right-angled strip structure, the right-angled side of the fixed plate 5 is lapped on the edge of the burner 1, and the fixed frame 6 is relatively screwed and The burner 1 is fastened on the fixed f...

specific Embodiment 2

[0021] Specific embodiment two: the difference between the present embodiment and embodiment one is that there is no splitter plate 8 under the air inlet 7, and the diameter of the small hole away from the air inlet 7 on the pressure divider 4 is greater than the diameter of the small hole near the air inlet 7 , except for these two differences, other structures and implemented functions are consistent with Embodiment 1.

[0022] In the technical solution of the present invention, the size of the small holes of the pressure dividing partition can be the same, and corresponding changes can also be made according to the wind pressure. Larger holes are opened in places where the wind pressure is small, and holes are opened in places where the wind pressure is high. It will be smaller; if the air inlet is small, a splitter plate will be installed at the air inlet to avoid the wind pressure at this place from being higher than other places. If the air inlet is larger, there is no ne...
