Description
Technical field
The utility model belongs to technical field of burner, and being concretely related to one kind can be realized full combustion, reduces oxygen
Change the dispersion gas distribution low nitrogen burning head of nitrogen content.
Background technique
Combustion head be constitute gas burner core component, structure affect fuel gas buring whether sufficiently and discharge
The height of the content of nitrogen oxide in tail gas.Reducing oxynitride discharge has positive meaning to environment, is current combustion gas
One of the main target of burner design.Existing major part combustor defect as present on the structure of combustion head, causes
NOx(oxynitrides in burning waste gas) content 80, between 200mg, is unable to meet the requirement of environmental protection.
Utility model content
The purpose of this utility model is just to provide a kind of dispersion gas distribution low nitrogen burning head that combustion efficiency is good.
To achieve the above object, the technology employed by the present utility model is
A kind of dispersion gas distribution low nitrogen burning head is set to including the outer tube body that can be connect with the air outlet of combustion fan
The intracorporal fuel gas conduit of the outer tube and the stable flame pan for being fixed on its end；It is characterized by: the diameter of the stable flame pan is less than described
The internal diameter of outer tube body, so that forming combustion air channel between the two；The stable flame pan is hollow disc structure, in the circle
The border of disk and its be provided centrally with several fuel gas holes.
Constitute a kind of above-mentioned additional technical feature for dispersing gas distribution low nitrogen burning head further include:
--- several combustion air hole is provided on the stable flame pan；
--- the front end for constituting the stable flame pan is provided with swirl vane；
--- the border of the stable flame pan is provided with swirl vane；
--- no less than one group of strong magnetic device is provided in the fuel gas conduit.
A kind of dispersion gas distribution low nitrogen burning head provided by the utility model compared with the existing technology, has the advantage that
First, the diameter due to the stable flame pan for constituting the combustion head is less than the internal diameter of the outer tube body, is formed help between the two
Air duct is fired, is sufficiently mixed with by the combustion gas sprayed in stable flame pan border and center fuel gas hole, is conducive to the abundant combustion of combustion gas
It burns；
Second, the combustion air hole due to being provided with several on stable flame pan, combustion air is sprayed by the hole to be formed
The air stream that heart air stream, the air stream and combustion air channel pass through with by being sprayed in stable flame pan border and center fuel gas hole
Combustion gas be sufficiently mixed, the full combustion of combustion gas can be further realized；
Third, due to being provided with swirl vane in the front end for constituting the stable flame pan；Therefore can make by combustion-supporting sky
The combustion air that stomata sprays forms Swirl shape air-flow, is conducive to the combustion gas of the fuel gas hole ejection of the air-flow and center setting
And the combustion gas by spraying in the fuel gas hole of stable flame pan border is preferably sufficiently mixed burning；
Third, since the border in stable flame pan is provided with swirl vane, can make by combustion air form eddy flow, into
One step improves the mixing of combustion-supporting air flow and combustion gas stream, improves the combustion efficiency of burner, can effectively reduce nitrogen oxidation conjunction
The generation of object, changing swirl vane angle can change the burning form of flame, can produce to form updraft, short-flame, flat flame etc.
Form meets the needs of different heating equipments；
Fourth, due to being provided with no less than one group of strong magnetic device, under the action of field of magnetic forece, Ke Yigai in fuel gas conduit
The molecules align form for becoming combustion gas, more preferably can more thoroughly burn, while saving energy, achieve the effect that low-nitrogen discharged.
Detailed description of the invention
Fig. 1 is to constitute a kind of structural schematic diagram for dispersing gas distribution low nitrogen burning head of the utility model；
Fig. 2 is the structural schematic diagram of stable flame pan.
Specific embodiment
With reference to the accompanying drawing to a kind of structure and work original of dispersion gas distribution low nitrogen burning head provided by the utility model
Reason is described in further detail.
Referring to Fig. 1,2, for a kind of structural schematic diagram for dispersing gas distribution low nitrogen burning head provided by the utility model.It constitutes
The structure of the dispersion gas distribution low nitrogen burning head includes the outer tube body 1 that can be connect with the air outlet of combustion fan, and it is outer to be set to this
The stable flame pan 3 managed intracorporal fuel gas conduit 2 and be fixed on its end；Wherein, the diameter of above-mentioned stable flame pan is less than the internal diameter of outer tube body,
So that forming combustion air channel 4 between the two；The stable flame pan is hollow disc structure, border and the center portion thereof in disk
Position is respectively arranged with several fuel gas holes 5, and several combustion air holes 8 are provided on the stable flame pan.
Its working principle is that combustion gas and combustion air are entered by its fuel gas inlet 6 and air intlet 7 respectively, i.e., combustion gas by
It is set in the border of disk and the fuel gas hole 5 at its center and sprays, and sprayed with by combustion air channel 4 and combustion air hole 8
Combustion air out is sufficiently mixed burning.
It constitutes in a kind of above-mentioned structure for dispersing gas distribution low nitrogen burning head:
--- its efficiency of combustion reduction nitrogen oxide is improved in order to will further improve the mixed effect of combustion air and combustion gas
Generation, the front end for constituting above-mentioned stable flame pan is provided with swirl vane circle 9；Or it is provided in the surrounding of above-mentioned stable flame pan
Swirl vane 10.The two, which can be used alone, to be applied in combination.
--- no less than one group of strong magnetic device 11 is provided in order to reach energy-saving effect in the combustion gas inner tube.
