Oxygen-enriched combusting space.
The utility model with no restrictions, can adjust the quantity of the first fire hole 111 and the second fire hole 112 as the case may be
It is whole.
Specifically, the first fire hole 111 in the present embodiment is radial fire hole, i.e. radial direction of the first fire hole 111 along side wall 11
Setting guarantees that the combustion gas supplied by the first fire hole 111 is sprayed towards the center position of combustion chamber.
In the present embodiment, the angle between the extending direction of the second fire hole 112 and the radial direction of side wall 11 is acute angle, ginseng
According to Fig. 2, the perspective view of the utility model combustion chamber is shown, this figure is only schematic diagram, does not represent the specific of the utility model
Structure.As shown, the direction that arrow A is directed toward in figure is the extending direction of the second fire hole 112, the direction that arrow B is directed toward is side
The radial direction of wall 11, angle α between the two are acute angle, can so make the combustion gas flowed into from the second fire hole 112 along combustion chamber
Circumferential direction rotate.
Second fire hole 112 can be straight hole, can also with as shown in Figure 1, include be parallel to side wall 11 tangential direction it is straight
Line segment, and the arc segment intersected with tangential direction.Specifically, being provided on side wall 11 multiple outstanding towards 11 outer surface of side wall

The the second fire hole entrance for protruding from 11 outer surface of side wall is formed in the vertical side of protrusion 113, it is more convenient convenient for external combustion gas
The second fire hole 112 of entrance, arc segment forms the outlet of the second fire hole in the inner surface of side wall 11, and guiding gas rotates into burning
It is indoor.
The invention also discloses a kind of burners using above-mentioned combustion chamber, referring to Fig. 3, Fig. 4, respectively illustrate this
The stereoscopic schematic diagram and cross-sectional view of utility model burner one embodiment.As shown, burner includes combustion chamber 1, shell
2, fire tube 31 kept burning day and night, ever-burning flame nozzle 32, ever-burning flame fire cover 33, main fire tube, main fiery gas joint 41, main fire-fighting mouth 42 and air hose
43。
Shell 2 is coated on the outside of combustion chamber 1, to form mixing chamber 101, the mixing chamber between shell 2 and combustion chamber 1
101 are connected to by the first fire hole 111, the second fire hole 112 with the inner space of combustion chamber.
Fire tube 31 kept burning day and night passes through the through-hole (not shown) on bottom wall 12, and is fixed on bottom wall 12.Ever-burning flame nozzle 32
It is connected to the outlet side of fire tube 31 kept burning day and night, protrude into the combustion space of combustion chamber 1 and is located at the center of combustion space bottom, so that the
The combustion gas of one fire hole 111 supply can be collected at ever-burning flame nozzle 32, and the inlet end of fire tube 31 kept burning day and night is provided with ever-burning flame and connects
First 34.Fire tube 31 kept burning day and night collectively constitutes the first blast tube with ever-burning flame nozzle 32, for supplying combustion gas into combustion space, and
So that combustion gas is from the center of combustion chamber along the Radial Flow of combustion chamber.
Ever-burning flame fire cover 33 is fixed on bottom wall 12, and is located at the outside of ever-burning flame nozzle 32, kept burning day and night in order to realize
The installation of fire cover 33, bottom wall 12 are provided centrally with recessed portion.It is peripherally disposed on the side wall of ever-burning flame fire cover 33 to have
Several stomatas 331, the combustion gas sprayed by ever-burning flame nozzle 32 is again by 331 flowing in combustion chamber 1 of stomata.
Since the aperture of ever-burning flame nozzle 32 is smaller, the gas flow passed through in the unit time is also smaller, in order to increase
Gas flow rate at aerating hole 331 is additionally provided with the mixed of the inner space of connection mixing chamber 101 and ever-burning flame fire cover 33 on bottom wall 12
Stomata 114, gas mixed hole 114 flow into ever-burning flame fire cover 33 for the gas in mixing chamber 101, increase in ever-burning flame fire cover 33
Pressure and gas flow, to increase the gas flow rate at stomata 331.
The bottom of mixing chamber 101 is connected to air hose 43, and main fire tube is connected to by main fiery gas joint 41, main fire-fighting mouth 42
On air hose 43, i.e., main fire tube is passed through combustion gas into air hose 43 first, and combustion gas enters back into after tentatively mixing in air hose 43 with air
It is mixed in mixing chamber 101, the incorporation time that can increase combustion gas and air is arranged such, so that the mixing of combustion gas and air
More uniformly.
It is logical that main fire tube, main fiery gas joint 41, main fire-fighting mouth 42, air hose 43 and mixing chamber 101 collectively constitute the second combustion gas
Road, it is mixed that the second blast tube can supply air-gas into combustion space by the first fire hole 111 and the second fire hole 112 respectively
Close gas.In use, the combustion gas that is sprayed by stomata 331 and being fired by the gas-air mixture body that the first fire hole 111 sprays
It burns and is mixed at the combustion with meagre oxygen space of room 1, since the gas concentration that stomata 331 sprays is very high, even if passing through the first fire hole
The 111 gas-air mixture bodies sprayed are broken up, and air content is still not enough to support mixed gas oxygen-enriched combusting, because
The heat that this combustion process is discharged is insufficient, and ignition temperature is relatively low, due to the generation efficiency and temperature of oxynitrides
It is positively correlated, therefore combustion with meagre oxygen can inhibit the generation of oxynitrides.After the completion of the burning of first stage, generation of burning
The gas-air mixture body that the combustion gas of flue gas and not yet after-flame is gradually fed with the second fire hole 112 again mixes, and carries out second
The burning in stage.When second stage is burnt, since the concentration of combustion gas declines, the oxygen-enriched combusting of fuel may be implemented, and by
In the presence for the flue gas that first stage burning generates, so that the oxygen concentration of second stage combustion process is still maintained at ignition temperature
Lower level, so can also equally inhibit the generation of oxynitrides.
In the present embodiment, the pipeline of burner and the resistance on head are small, select low-power fan that can meet requirement,
Also have many advantages, such as that energy conservation and environmental protection, noise are small.
Referring to Fig. 5, the stereoscopic schematic diagram of the main fire-fighting mouth one embodiment of the utility model is shown.As shown, main fire
Nozzle includes the interconnecting piece 431 connecting with air hose 43, and the interconnecting piece 432 connecting with main fiery gas joint 41, interconnecting piece 431
On be provided with locating slot 433 and index line 436, locating slot 433 and index line for realizing main fire-fighting mouth and air hose 43 positioning
Connection.
Be provided with inclined-plane 434 on interconnecting piece 432, be provided with main fire-fighting mouth 435 on inclined-plane 434, the setting on the inclined-plane so that
The air flow direction that the combustion gas flow direction for entering air hose 43 from main fire-fighting mouth 435 is in reverse in air hose 43, to realize combustion gas and air
More preferable mixing." being in reverse to " referred to herein is not strictly defined as combustion gas flow direction and is substantially parallel with air flow direction, allows two
There are certain drift angles between person.
The invention also discloses a kind of gas-cookers using said burner.
It is illustrating for progress to be implemented to the preferable of the utility model, but the invention is not limited to the reality above
Example is applied, those skilled in the art can also make various equivalent variations without departing from the spirit of the present invention
Or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
