Description

Burner
Technical field
The utility model provides a kind of burner, especially a kind of atmospheric burner being applied on inlaid gas range.
Background technology
Civil kitchen range all uses atmospheric burning type method, this is because this kind of burner, premix part air, make combustion flame short, firepower is strong, temperature is high, and efficiency of combustion is higher than diffusion type combustion system, the combustion gas of different nature of can also burning, combustion completion, can be applicable to low-pressure fuel gas, and do not need other power-equipment, so be more suitable for domestic gas appliance than other combustion method.But the atmospheric burner of traditional kitchen range is due to domestic source of the gas complexity, processing technology falls behind, people are less demanding to cooking apparatus, as long as can burn, think little of also not pursuing accurate and good combustion conditions, the technical capability of manufacturing producer is also low, and a lot of products all do not reach existing national standard.Particularly be applicable to Chinese way of cooking vigorous fire and fry fried traditional function, the required power that is bound to is large, low emission, and combustion stablized burner is used in conjunction with it.
Mainly there is following problem in conventional burners:
1. in order to coordinate the needs of the cooking, often require burner to there is larger power (more than 4.5kW), and conventional way is not take the principle of atmospheric burning type mode into account now, the parameter that does not change injector just increases gas flow, thereby generation imperfect combustion, causes harmful effect to health; Increase burning area, makes it burner head and increases, and owing to having expanded heating surface area, the thermal efficiency is reduced.
2. traditional gas kitchen ranges all needs conditioner, changes to adapt to source of the gas " de-fire ", the rough burning phenomenon of " Huang Yan " and " tempering " that (pressure, composition) causes.And the kitchen range of in fact embedded installation, due to structures shape user be difficult to regulate or can not regulate air capacity.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and has high-power, low emission, exempted from the atmospheric burner that air door regulates.
For achieving the above object, the technical solution of the utility model is:

As preferably, the air inlet duct of gas distribution chamber base outer wall setting is at least 2, and each air inlet duct equates with respect to the height of gas distribution chamber base.
As preferably, the length of air inlet duct (arc length) is at least 60mm, is highly at least 8mm.
As preferably, outer burner is one-body molded, and the upper and lower surface of outer burner is horizontal plane, on the outer wall of combustion outer device, offer outer main fire hole and outer stable flame hole, fire hole is Dual-layer structure, the outer main fire hole footpath on upper strata is greater than the outer stable flame hole footpath of lower floor, and large and small different main fire, stable flame hole are alternately.
As preferably, the upper and lower surface of inner burner is horizontal plane, on the outer wall of inner burner, offers stable flame hole.
As preferably, on outer burner, in plane, do not establish fire hole.
As preferably, the upper and lower surface of inner burner is horizontal plane, offers inner main fire hole and interior stable flame hole on the outer wall of inner burner, and fire hole is Dual-layer structure, the inner main fire hole footpath on upper strata is greater than the interior stable flame hole footpath of lower floor, and large and small different main fire, stable flame hole are alternately
Compared with prior art, the beneficial effects of the utility model are:
1. changed the injector design of conventional burners, the function of mixing tube and the total length of injector are set up, increase fire hole area (having increased fire hole area in setting up stable flame hole) at burner head, cancel the middle fire hole of outer head, reach theoretically best mass ratio of induced-to-inducing air, reduced auxiliary air requirement.The diameter that need not increase gas distribution chamber and head improves power, has accomplished truly high-power, and because the ejector capacity of injector is large, makes in fume emission carbon monoxide content ultralow.
2. changed the fire hole spread pattern of traditional burner, the substitute is main fire hole and the stable flame hole with flame stabilization function, produce two kinds of different fire output hole air velocities, steady flame structure matches with the secondary air inlet structure of gas distribution chamber base, carry out feeding secondary air by the fixed air air inlet duct arranging on gas distribution chamber base, such structure has just reduced the height of overall kitchen range, guarantee air inlet amount and auxiliary air air velocity, to reach smooth combustion, exempt from the object of air register.
