When an outlet flow of the fire holes is certain, more air can be sucked, so that the gas combustion efficiency can be improved; the heating effect is more uniform; the heat absorption efficiency is higher; the combustion efficiency can be greatly improved; the emission of CO and NOx can be reduced; and the national environmental friendliness standard can be reached.

Description

A kind of petal type burner
Technical field
The utility model relates to household gas utensils, is specially a kind of petal type burner.
Background technology
Domestic gas-cooker more early uses DC burner, and fire hole 1 comparatively disperses, and combustion flame is difficult fully to be mixed with auxiliary air, causes efficiency of combustion to descend, and CO and NOx discharge capacity are high in the flue gas, can make the kitchen range decrease in efficiency, waste energy.What domestic application or gas-cooker newly developed generally adopted at present is turbulent burner, although turbulent burner can utilize the swirl injection principle to produce stable inward turning flame combustion, simultaneously combustion gas smoke mixture can have reasonable the mixing with auxiliary air, the space but efficiency of combustion also improves a lot, CO and NOx are larger in the fume emission simultaneously.If the location arrangements of cyclone fire hole 1 is unreasonable, then the content of CO can sharply rise in the flue gas.The main flow gas-fired range with vortex burner efficient of selling in the market is all about 53%.
Summary of the invention
The purpose of this utility model is to provide a kind of petal type burner, and the existing burner CO of solution and the problem that the NOx discharging is large and efficiency of combustion remains further raising are to reach the national energy-saving environmental protection standard.
A kind of petal type burner that the utility model provides is characterized in that this burner comprises fire hole seat, mixing chamber, pedestal, induction tunnel and nozzle, and nozzle inserts in the end of induction tunnel, and an end of the other end of induction tunnel and pedestal is connected; The pedestal other end is fixedly connected with the bottom of mixing chamber, and the fire hole seat is installed in the top of mixing chamber, is furnished with the petal type fire hole above the fire hole seat, and fire hole is regular arrangement in a circumferential direction.
As improvement of the technical scheme, the quantity of described petal type fire hole is 3~7, and the lobe number of each fire hole is 4~8.
As further improvement in the technical proposal, the outlet of described fire hole is 8~12mm. apart from the distance on fire hole seat top
As the further improvement of technique scheme, described nozzle is made of three jet pipe mouths that are positioned on the nozzle carrier at least, and the angle between the center line of each jet pipe and described induction tunnel is 5 to 9 degree.
As further improving again of technique scheme, the spacing between each fire hole is about 15mm; The height of fire hole is about 7mm; The number of fire hole is 3~6.
During the utility model work, fuel is sprayed by nozzle, and injection portion of air (primary air) enters mixing chamber by induction tunnel under certain pressure, and auxiliary air can be carried by the injection of petal type fire hole self.(primary air refers to because the nozzle ejector action enters combustion tube by the air of nozzle ejection with fuel, and auxiliary air refers in the combustion process from additional air of surrounding air week).
The utility model adopts the petal type fire hole, and it is strong to compare common fire hole ejector capacity, and mass ratio of induced-to-inducing air is large, at fire hole rate of discharge one regularly, can entrainment more air, and gas-cooker efficient is improved, and makes heating more even, and heat absorption efficiency is higher.If general gas-fired range with vortex burner reduces the distance of the bottom of a pan and fire hole, can produce the Means of Secondary Air Supplement deficiency, incomplete combustion produces black smoke, causes inefficiency, energy waste.Adopt gas-cooker of the present utility model then not have these problems, when petal fire hole and the bottom of a pan close together, CO and NOx discharging are all very low.Proof adopts gas-cooker of the present utility model by experiment, and the heat absorption efficiency of pot face has reached 65%, and the CO discharge capacity is below 100ppm simultaneously, and the NOx discharge capacity is below 100ppm, well below national energy-saving environmental requirement index.
Description of drawings
The schematic perspective view of the petal type burner that Fig. 1 provides for the utility model;
The petal type burner top view that Fig. 2 provides for the utility model;
Fig. 3 is A-A cutaway view among Fig. 2.
Among the figure, petal fire hole 1, fire hole seat 2, mixing chamber 3, pedestal 4, induction tunnel 5, nozzle 6.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.Need to prove at this, understand the utility model for the explanation of these embodiments for helping, but do not consist of restriction of the present utility model.In addition, below in each embodiment of described the utility model involved technical characterictic just can mutually not make up as long as consist of each other conflict.
As shown in Figure 1, the petal type burner that the utility model provides comprises nozzle 6, induction tunnel 5, pedestal 4, and nozzle 6 inserts in the induction tunnel 5, and induction tunnel 5 is connected with pedestal 4.Fire hole seat 2 is installed in the top of mixing chamber 3, is furnished with in a circumferential direction regular arrangement of petal type fire hole 1,1 fire hole above the fire hole seat 2.
Mixing chamber 3 is the cylindrical shape of enlarging.Be furnished with N petal type fire hole 1 above the fire hole seat 2, N=3~7, the lobe number of each petal is 4~8, fire hole 1 outlet is 8~12mm apart from the distance on fire hole seat 2 tops.
Fire hole 1 is regular arrangement in a circumferential direction.
Fire hole seat 2 and petal type fire hole 1 link to each other by pipe, and 6 one-tenth at several nozzles become 7 ± 2 degree with horizontal line, are arranged in the main burner joint.
In Fig. 2, fuel is by nozzle 6 ejections, and injection portion of air (primary air) enters mixing chamber 3 by induction tunnel 5 under certain pressure, and auxiliary air can be replenished by petal fire hole 1 injection.The fuel of process premix and the mixture of air, are sprayed by fire hole seat 2 top petal fire holes 1 to mixing chamber 3 through induction tunnel 5.
The area of petal fire hole 1.The height of petal fire hole 1.The number of petal fire hole 1.These structural parameters can be determined by power and the combustion gas kind of gas-cooker.
Petal fire hole 1 spacing about 15mm, petal fire hole 1 height can obtain preferably combustion efficiency during in the 7mm left and right sides.The number of petal fire hole 1 is 3~6, and allows to adjust above parameter according to gas-cooker power needs.
The position of each fire hole 1 has determined degree that firepower is concentrated and the situation of burning.If fuel is different, gas-cooker power is different, then the condition of the formation of its CO and NOx is different with the position, then the dimensional parameters of single fire hole 1 is just different, by adjust petal fire hole 1 size can so that fuel in suitable zonal combustion, both be conducive to burning fully, can have suppressed again the generation of NOx, to reach the high-efficiency cleaning burning.
Before making eye bright, application form also do not find to use the combustion technology of petal type burner.The use of this burner can reduce the discharging of CO and NOx in the flue gas in a large number, improves simultaneously whole heat absorption efficiency.If first and second air coefficient is carried out excellent design, with each petal type fire hole 1 size and position reasonable Arrangement, then the heat absorption efficiency of pot face further raises, and CO and NOx discharging will further reduce in the flue gas simultaneously.
Those skilled in the art will readily understand; the above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
