Description
Technical field
The present invention relates to a kind of gas burner, refers specifically to a kind of shade burner.
Background technology
The burner that traditional domestic gas-fired water heater or gas-heating bathing dual-purpose stove is used, is common row pattern
Operationally, combustion flame localized hyperthermia, burning often not enough fully, is produced in combustion process for burner, generally these burners
Life more CO and NOx, pollutes surrounding environment.
ZL200720047752.9 is disclosed《A kind of pair of flame burner》, this pair of flame burner include separate light combustion
Gas feed system and dense gas supply system, light gas supply system is arranged on the outside of dense gas supply system, dense fire hole and
Light fire hole length is interlocked, and light combustion flame adopts complete pre-burning mode, and flame is relatively short, and dense combustion flame adopts part pre-burning
Burning mode, flame is relatively long.So length of flame mode staggeredly is to a certain extent similar to dividing that fuel staging is supplied
Section burning, is conducive to improving efficiency of combustion.
For another example disclosed in ZL200920068968.2《The fire row of low nitrogen oxygen combustor used for wall-mounted boiler》, it includes fire row sheet
Body and burner set, burner set is sheathed at the dense fiery blast tube position of fire row body, and described burner puts and is provided with positioned at interior
The dense fiery pressure stabilizing cavity of side, dense burner, the light fiery blast tube positioned at outside, light burner and light with what light fiery blast tube was connected
Fiery air duct, the dense fiery pressure stabilizing cavity of dense fiery blast tube Jing is connected with dense burner, and dense fiery blast tube both sides are provided with tap hole, should
The light fiery blast tubes of tap hole Jing are connected with light burner.Fire row simple structure, the low cost, are not changing the former knot of common wall-hung boiler
On the basis of structure, low-nitrogen discharged, the thermal efficiency of the former wall-hung boiler of raising is can reach.Although, it is above-mentioned dense relative to traditional burner
Light burner adopts and efficiency of combustion can be improved after bias combustion, but is all by secondary sky during light flame supplement auxiliary air
The light fiery air ducts of gas Jing mix into light fiery blast tube with gas secondary, constitute light fiery combustion gas mixing gas, and and then logical
Crossing light burner becomes light flame combustion, it is seen that the light flame of the burner does not have single auxiliary air to supplement passage, secondary sky
Gas supplementary result need to be improved.Additionally, light flame is not easily accomplished in combustion steady flame, light flame to dense flame two
Secondary air supplementary result is poor, so that the total combustion of burner is abundant not enough.
The content of the invention
The technical problem to be solved is a kind of abundant and steady flame effect of burning of present situation offer for prior art
Really good shade burner.
The present invention solve the technical scheme that adopted of above-mentioned technical problem for：The shade burner, including fire row, the fire

On inwall；Enclose to form the first mixed air cavity, the light inner cone between the inwall of the rich flame central layer and the rich flame passage for being connected
Enclose to form the second mixed air cavity between the inwall of plate and corresponding light flame passage；
The first pore of the described first mixed air cavity and the rich flame passage is communicated with the rich flame central layer；The light flame
The second pore of the described second mixed air cavity and the light flame passage is communicated with central layer；
Multiple tonifying Qi holes that auxiliary air is supplemented into light flame channel lumen are additionally provided with the wall of the light flame passage；
The rich flame hole is arranged on the top surface of the rich flame passage；The light flame hole is arranged on the top of the light flame passage
On face.
Preferably, the lower surface of the light flame passage can be inclined-plane；Each tonifying Qi hole is arranged on the inclined-plane
On.The structure forms injection effect, and auxiliary air fills into smooth, air compensation foot.
Two fire rows are arranged symmetrically the fire row unit to form the light flame hole in interior, rich flame hole outside；It is described deep or light
Burner is be arranged in parallel by multiple fire row units and is formed；
Gap between adjacent fire row unit forms the secondary air compensating passage of dense flame.
Compared with prior art, shade burner provided by the present invention, dense flame and light flame are complementary to one another, and not only carry
High efficiency of combustion, it is ensured that the abundant burning of combustion gas, and dense flame also there is good steady flame to act on light flame, it is to avoid
From the generation of flame phenomenon；And dense, light flame arranged for interval, it is to avoid burner localized hyperthermia.

Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 4, the shade burner is arranged in parallel by multiple fire row unit Bs and is formed, adjacent fire row unit it
Between gap formed to dense flame supplement auxiliary air secondary air compensating channel C.
Each fire row unit B includes two symmetrically arranged fire rows A.
Fire row A includes：
Induction tunnel 1, by air in fuel gas flow injection surrounding environment, for supplementing primary air in combustion gas；Can root
According to need from it is of the prior art any one.
Rich flame passage 51 and light flame passage 52, enclosed construction, its lower surface is inclined-plane；The inclined-plane 54 of light flame passage is provided with
Multiple tonifying Qi holes 53 for supplementing auxiliary air into light flame passage；Ora terminalis under rich flame passage 51 and the light lateral wall of flame passage 52
It is connected on the outer wall of rich flame central layer 41 and light inner cone plate 42；The top surface of rich flame passage 51 is provided with rich flame hole 2, and light flame leads to
The top surface in road 52 is provided with light flame hole 3.
Rich flame central layer 41 and light inner cone plate 42, are symmetrical arranged, and both lower ora terminalis are arranged oppositely to form connection induction tunnel 1
The fuel gas inlet of gas outlet；Its upper edge is connected on the corresponding inwall of rich flame passage 51 and light flame passage 52.
Enclose to form the first mixed air cavity 61, light flame between rich flame central layer 41 and the corresponding inwall of the rich flame passage 51 for being connected
Enclose to form the second mixed air cavity 62 between central layer 42 and the inwall of the corresponding light flame passage 52 for being connected.
The first pore 43 of the first mixed air cavity 61 and rich flame passage 51 is communicated with rich flame central layer 41；On light inner cone plate 42
It is communicated with the second pore 44 of the second mixed air cavity 62 and light flame passage 52.
During burner operation, combustion gas and the primary air for filling into carry out mixed once, mixed once gas Jing in induction tunnel
Respectively enterd in the first mixed air cavity and the second mixed air cavity by fuel gas inlet, mixed once gas is in the first mixed air cavity and the second mixed air cavity
Inside mixed again, again uniform mixed mixed once gas respectively enters dense smoke via each first pore and the second pore
In passage and light flame passage.
Three mixings are carried out in rich flame passage into the mixed once gas in rich flame passage, is then sprayed via rich flame hole
Burning, forms the high dense flame of temperature height, flare.Dense flame makes in burning, and air adds to dense fire via secondary supplement channel C
On flame, it is ensured that the abundant burning of dense flame.
Mixed once gas and the air being added into light flame passage via tonifying Qi hole mix in light flame passage, are formed secondary
Gaseous mixture, secondary gaseous mixture sprays burning via each light flame hole, forms the light flame that temperature is low, flare is little.
Dense flame and light flame are complementary to one another, and not only increase efficiency of combustion, it is ensured that the abundant burning of combustion gas, and dense fire
Flame also there is good steady flame to act on light flame, it is to avoid from the generation of flame phenomenon；And dense, light flame arranged for interval, keeps away
Exempt from burner localized hyperthermia.
