The changeover portion 320 of above-mentioned mixing chamber 32, first contraction section 321, diffuser 322 and second contraction section 323 are realized the mobile ignitable fuel of certain pressure and air transition, contraction, diffusion by cone Wen tubular structure and are shunk, mix more fully, keep of fumarole 6 ejection of certain kinetic energy from gaseous mixture spout 4.
Above-mentioned gaseous mixture spout 4 comprises a plurality of fumaroles 6 that cross and distribute.
The center line of above-mentioned fumarole 6 prolongs and is intersected in a bit.The realization fuel combination collides mutually further and mixes with air.
Said nozzle injection suction hole comprises two circle nozzle injection suction holes.
A kind of fuel injection collides sets of burners mutually, and its special character is: is that 50～70 angles of spending rearrange by a plurality of above-mentioned burners by angle.A plurality of burners are arranged according to certain angle the combustible that each burner gushes out is bumped once more, fully mix once more, general angle 50～70 degree just can ensure fully and mix, certainly be not confined in such angular range, mix as long as can ensure fully in principle.
The angle of above-mentioned angle is good with 60 degree.
Each burner spray centerline is intersected in a bit in above-mentioned a plurality of sets of burners.The combustible that ejects like this can collide once more, reaches and the well-mixed once more purpose of air.
The utility model modern design, simple in structure, collision mutually takes place repeatedly in combustible in the process of its ejection, it is abundant more, even that combustible is mixed with air, sufficient combustion, flame stabilization is difficult for producing yellow flame, tempering, taking off fire, burning back smoke pollution is minimum, is significantly less than state-set standard index environment protection emission.

The specific embodiment
Referring to Fig. 1, a kind of fuel injection collides burner mutually, comprise cavity 3, inlet nozzle 2 and gaseous mixture spout 4, inlet nozzle 2 and gaseous mixture spout 4 are positioned at the two ends of cavity 3, and inlet nozzle 2 is extended by the pipeline that is connected with burner 1 and constitutes, pipeline 1 by attaching nut 11 with connect mouth 12 and be connected, the described mouth 12 that connects is provided with nozzle bore 121 and nozzle injection suction hole 122 (actual can set the aperture according to required rated heat input, rated heat load), and nozzle bore 121 is connected with inlet nozzle 2; Cavity 3 comprises induction chamber 31 and mixing chamber 32 two parts, and induction chamber 31 is provided with opening 5, and mixing chamber 32 comprises changeover portion 320, first contraction section 321, diffuser 322 and second contraction section 323.Nozzle bore 121 is connected with induction chamber 31 by inlet nozzle 2, at 31 ejector actions of induction chamber.The changeover portion 320 of mixing chamber 32, first contraction section 321, diffuser 322 and second contraction section 323 are realized the mobile ignitable fuel of certain pressure and air transition, contraction, diffusion by cone Wen tubular structure and are shunk, mix more abundant, keep of fumarole 6 ejections of certain kinetic energy from gaseous mixture spout 4, gaseous mixture spout 4 comprises a plurality of fumaroles 6 that cross and distribute, the center line of fumarole 6 prolongs and is intersected in a bit, realizes that fuel combination collides further mutually to mix with air.Nozzle injection suction hole comprises two circle nozzle injection suction holes.
