The one end for stating injection section 13 is provided with the air admission hole 10, and the bottom of the other end of the injection section 13 and the mixing section 14 connects
Logical, the top of the mixing section 14 connects with the bottom of the flame cavity 15, and the top of the flame cavity 15 is provided with described
Combustion front 12.In the course of work of the burner, the temperature of the flame cavity 15 can be the whole burner highest
A part, the combustion front 12 on the top of especially described flame cavity 15, in order to reduce the flame cavity 15 especially
It is the temperature of the combustion front 12, at least two straight lengths 20,21,22 is sequentially passed through described in all fire rows 1
Flame cavity 15, and the position run through is relative two side of each flame cavity 15.
It is preferred that referring to Fig. 3, the injection section 13 of each fire row 1 is horizontally disposed (horizontally disposed to refer to
When the burner normal work, each the injection section 13 is horizontal), and the mixing section 14 of each fire row 1
Be U-shaped, can so cause the mixing section 14 length and the injection section 13 length it is long, so as to make
Combustion gas and air are sufficiently mixed and that combustion gas is offered in the flame cavity 15 is each in the mixing section 14
Fully burnt in the individual fire hole 11, and then can further reduce the discharge of the nitrogen oxides of the burner (because combustion gas
Burning insufficient can produce substantial amounts of nitrogen oxides).
In above-mentioned utility model embodiment, it is preferable that refer to Fig. 1, the water cooling pipeline of fire row 1 also includes the first arc
The arc pipeline section 24 of shape pipeline section 23 and second, three straight lengths 20,21,22 points be the first straight length 20, the second straight length 21
