The stability of combustion flame and the thermal efficiency of burning are all related with burning fire row.
However, the fire hole of existing burning fire row is lateral bar shaped distribution, and fire hole face is plane, leverages burning
The efficiency of combustion of device, therefore, existing burner are urgently improved.
Utility model content
The technical issues of to overcome existing burner combustion low efficiency, the utility model provide a kind of new and effective combustion gas
Wall hanging burner.
To achieve the above object, the utility model provides the following technical solutions: a kind of new and effective burnt gas wall hanging furnace burning
Device, including burner head and burning mixing chamber, wherein burner head setting is above burning mixing chamber, and burner head
It is connected to burning mixing chamber；The burner head is equipped with the burning fire row rearranged by several fire hole groups；Each fire
Hole group is made of rectangle fire hole with the round fire hole that rectangle fire hole both ends are arranged in respectively；The burning mixing chamber by contraction section,
Aditus laryngis, mixing section and diffuser are constituted, and wherein contraction section is connected to aditus laryngis, and aditus laryngis is connected to mixing section, mixing section and diffuser
Connection, diffuser are connected to burner head.
Preferably, the V-shaped structure in fire hole face of the rectangle fire hole.
Preferably, the V-shaped structure in fire hole face of the round fire hole.
Preferably, the clearance distance between the adjacent two fire holes group is 15~25mm.
Compared with the existing technology, the beneficial effects of the utility model are: on the basis of original burning fire row, monnolithic case
Size constancy preferably improves combustion conditions, flameholding by changing the size and fire hole shape of fire row key position
Property, safety is higher, further increases specified heat input, and burning and exhausting amount is low, greatly reduces the discharge of CO in flue gas
Content.

Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is A-A schematic cross-sectional view shown in Fig. 1；
Fig. 3 is the utility model burning fire row structural schematic diagram；
Fig. 4 is structure enlargement diagram at B shown in Fig. 3.
Drawing reference numeral explanation:
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment
It is only used for explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as
When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.
The utility model proposes a kind of new and effective fuel wall hanging burners.
Incorporated by reference to referring to figs. 1 to Fig. 4, a kind of new and effective fuel wall hanging burner, including burner head 10 and combustion
Mixing chamber 20 is burnt, wherein the setting of burner head 10 is above burning mixing chamber 20, and burner head 10 and burning mixing chamber
20 connections.
Burner head 10 is equipped with the burning fire row 40 rearranged by several fire hole groups 30, wherein adjacent two fire holes group 30
Between clearance distance be 15~25mm.Each fire hole group 30 by rectangle fire hole 301 and is arranged at 301 both ends of rectangle fire hole respectively
Round fire hole 302 form.
In the present embodiment, fire hole group 30 is combined by using rectangle fire hole 301 and round fire hole 302, can not only be by combustion gas
What is be distributed is more uniform, is also conducive to gaseous mixture and contacts with auxiliary air, and resistance is smaller, is conducive to increase primary air, reduce
The discharge of CO in flue gas.In addition with the variation of gaseous-pressure, the flame of this structure resists from flame better performances, flame stabilization.
The V-shaped structure in fire hole face 3011 of rectangle fire hole 301, the V-shaped structure in the fire hole face (figure of round fire hole 302
Do not show).
In the present embodiment, " V " type structure is respectively adopted in the fire hole face of rectangle fire hole 301 and round fire hole 302, thus make,
The flame root of rectangle fire hole 301 and round fire hole 302 and the area of burning 40 contact surface of fire row are bigger, and flame root is pricked more
Surely, combustion stability improves.
Burning mixing chamber 20 is made of contraction section 201, aditus laryngis 202, mixing section 203 and diffuser 204, wherein contraction section
201 are connected to aditus laryngis 202, and aditus laryngis 202 is connected to mixing section 203, and mixing section 203 is connected to diffuser 204, diffuser 204 with
Burner head 10 is connected to.
In the present embodiment, integral burner size constancy is kept, by shortening the length of diffuser 204 and mixing section 203,
On-way resistance is reduced, convenient for increasing primary air, reduces the discharge of CO in flue gas；When wherein contraction section 201 is used for injection air
Drag losses；Aditus laryngis 202 is used to control the soakage of primary air；Mixing section 203 is sufficiently merged for combustion gas with air
(speed, concentration)；For diffuser 204 for making the part dynamic pressure in mixing chamber become static pressure, the pressure of Lai Tigao gas reaches combustion
Operating pressure needed for burner head 10；Burner head 10 is for uniformly dividing air, fuel gas mixture less than each fire hole group
On 30, and carry out stable and completely burned.
For the utility model on the basis of original burning fire row, overall dimension is constant, by changing fire row key portion
The size and fire hole shape of position, preferably improve combustion conditions, combustion stability, safety is higher, further increases specified
Heat input, and burning and exhausting amount is low, greatly reduces the discharge content of CO in flue gas.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
