Embodiment Construction
[0014] The present invention will be further described below in conjunction with the drawings.
[0015] Such as figure 1 Shown. The present invention is a gas-air mixer of a fully premixed gas burner, which comprises a gas inlet pipe 1, a gas distribution plate 5 and a gas mixing and stirring faceplate 6. The gas inlet pipe 1 includes a gas inlet pipe transverse pipe and a gas inlet pipe vertical pipe. The outer port of the gas inlet pipe transverse pipe is a gas inlet port 10, and the gas inlet pipe vertical pipe outer port is provided with a gas nozzle 4 along the circumference. The gas nozzle 4 adopts a ring-shaped porous arrangement, which is distributed horizontally at 360 degrees. An air baffle is provided on the horizontal pipe of the gas inlet pipe near the inner port of the gas nozzle 4 to form a gas entering the vertical pipe of the gas inlet pipe from the direction close to the secondary air inlet damper 7 so that the gas can be in the vertical pipe of the gas inlet p...

The invention discloses a fuel gas and air mixer for a fully-premixed fuel gas burner and belongs to the technical field of fuel gas equipment. The fuel gas and air mixer mainly aims at solving the problem that an existing fully-premixed fuel gas burner is not good in fuel gas and air premixing effect. The fuel gas and air mixer is mainly characterized in that the fuel gas and air mixer comprisesa fuel gas inlet pipe, a fuel gas distribution disc and a gas mixing and stirring faceplate; the fuel gas inlet pipe comprises a fuel gas inlet pipe transverse pipe body and a fuel gas inlet pipe vertical pipe body, and fuel gas nozzles are formed in the circumference of an outer end opening of the fuel gas inlet pipe vertical pipe body; the fuel gas distribution disc and the gas mixing and stirring faceplate are arranged at the outer side of the outer end opening of the fuel gas inlet pipe vertical pipe body in a spaced manner; a vertical air inlet pipe is arranged in the center of the fuel gas inlet pipe vertical pipe body, a secondary air inlet air door is arranged at one end of the vertical air inlet pipe, and the tail end of the other end of the vertical air inlet pipe is blocked; andair outlets are formed in the circumference of the upper portion of the tail end of the vertical air inlet pipe. The fuel gas and air mixer has the beneficial effects that the structure is compact; the layout is reasonable; and the fuel gas and air mixer is well combined with other components inside the burner. The fuel gas and air mixer is mainly used for mixing fuel gas and air for the fully-premixed fuel gas burner.
Description
Technical field [0001] The invention belongs to the technical field of gas equipment. Specifically, it relates to a gas and air mixer for a fully premixed gas burner. Background technique [0002] Fully premixed gas burner is a kind of gas burner composed of combustion fan, gas nozzle, gas air mixer, premixing cylinder and combustion head. It is required to premix gas and air inside the burner, and the flame is burning. Burner burning on the head surface. [0003] Fully premixed gas burners generally use combustion-supporting air to blow up air, and gas nozzles use multi-pipe oblique blowing to blow air. The disadvantage is that the air supply is single, the air supply point is few, and the combustible gas stroke is short after mixing. The gas and air cannot be fully mixed, resulting in uneven combustible gas composition at the outlet of the combustion head, insufficient combustion of the burner, and reduced combustion efficiency. CO, CO in flue gas 2 Issues such as the rise of ...
