[0002] The low oxygen and low nitrogen oxide burner head is a key component of the low oxygen and low nitrogen oxide burner, which is mainly used to control and optimize the combustion process of the fuel to reduce the emission of nitrogen oxides. The design principle of the low oxygen and low nitrogen oxide burner head is to reduce the generation of oxygen and low nitrogen oxides by improving the mixing ratio of fuel and air, and controlling the temperature and oxygen supply during the combustion process. In the traditional combustion process, high temperature and sufficient oxygen are the main reasons for the large-scale generation of nitrogen oxides. During the use of the low oxygen and low nitrogen oxide burner head in the prior art, the gas combustion is not sufficient, resulting in relatively high carbon monoxide and carbon dioxide emissions, which is not energy-saving and environmentally friendly. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a low-oxygen and low-nitrogen oxide burner head, which, through the mutual cooperation of the external combustion kit, the internal air distribution kit, the flange, the end cover and the bridge, can achieve the balance of combustible gas during use, and has the functions of no backfire and no flameout, thereby promoting the effect of energy saving and environmental protection.

[0004] To solve the above technical problems, according to one aspect of the utility model, the utility model provides the following technical solution: a low-oxygen and low-nitrogen oxide burner head, comprising an outer combustion kit, an inner air distribution kit being fitted inside the outer combustion kit, a flange being provided at the bottom of the outer combustion kit, an end cover being provided at the top of the inner air distribution kit, and a bridge being provided on the outer side wall of the outer combustion kit.

[0005] As a preferred solution of the low-oxygen and low-nitrogen oxide burner head described in the utility model, the flange is stamped and formed, and two steps are arranged on the top of the flange.

[0006] As a preferred solution of the low-oxygen and low-nitrogen oxide burner head described in the utility model, circular holes are arranged on the surface of the flange, and the circular holes are distributed in a ring shape.

[0007] As a preferred solution of the low-oxygen and low-nitrogen oxide burner head described in the utility model, two steps are arranged on the surface of the end cover, and the size of the steps of the end cover is the same as the size of the flange.

[0008] As a preferred solution of the low-oxygen and low-nitrogen oxide burner head described in the utility model, it also includes an adjustment component, and a plurality of bridge frames are provided, and the bridge frames are distributed in an annular staggered manner.

[0009] As a preferred solution of the low-oxygen and low-nitrogen oxide burner head described in the utility model, the flange and the outer combustion kit are welded to each other, and the end cover and the inner air distribution kit are welded to each other.

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] By cooperating with each other, the external combustion kit, the internal air distribution kit, the flange, the end cover and the bridge, the combustible gas can be balanced during use, and the functions of no backfire and flameout can be achieved, thereby promoting the effect of energy saving and environmental protection.

[0012] During specific use, with the cooperation of the matching fan and gas valve group, after the air and natural gas or hydrogen and other combustible gases are mixed in the inner air distribution kit, the mixed gas flows out evenly from the aperture on the inner air distribution kit under the pressure of the fan and natural gas until it reaches the outer combustion kit, and is sprayed from both sides of the bridge of the outer combustion kit. With the assistance of the electronic ignition device of the outer combustion kit, the mixed combustible gas is successfully ignited. The inner air distribution kit evenly distributes air to the combustible gas at one time. Due to the special bridge structure of the outer combustion kit, the mixed combustible gas is sprayed from the gaps on both sides of the bridge. The combustion flame is evenly distributed in the entire cylindrical barrel, and each bridge sprays combustible gas evenly. The combustion flame temperature is controlled within a certain range, and the conditions for the chemical reaction of oxygen and nitrogen in the air at high temperature are not met, so the conditions for controlling the generation of nitrogen oxides are met, and the combustible gas combustion is fully controlled, and the emissions of carbon monoxide and carbon dioxide are extremely low, with indicators of low oxygen and low nitrogen oxides, thereby achieving energy saving and environmental protection.
