Abstract
The utility model relates to the technical field of gas stoves, in particular to a surface combustion member and a combustor head thereof. The surface combustion member comprises the surface combustion member comprising a barrel-shaped metal fiber net, and is characterized in that the barrel wall profile of the barrel-shaped metal fiber net is gear-shaped. The barrel wall profile can be in the shape of an arc tooth gear or a triangular tooth gear. The barrel-shaped metal fiber net is in the shape of a straight barrel or a conical barrel. The surface combustion member has the benefits as follows: when the volume of the combustor head is slightly increased, the surface combustion area of a metal fiber is greatly enlarged, the combustion strength can be reduced, the combustion stability can be improved, and the service life of the surface combustion member of the metal fiber can be prolonged.
Description
Technical field
The utility model relates to the gas-cooker technical field, relates in particular to a kind of surface combustion member and burner head thereof.
Background technology
Along with the growing interest of people for environmental problem, country requires more and more stricter to NOx concentration of emission in the flue gases such as kitchen range, boiler, industrial furnace. and adopting the surface combustion technology is one of effective way that reduces the NOx concentration of emission, metal fiber burner is a kind of novel surface formula gas burner that in recent years occurs, has the low characteristic of NOx concentration of emission, because metal fiber burner can carry out fuel gas buring with infrared emanation combustion system or blue combustion mode, is the effective measures of energy-saving and emission-reduction.The patent No. is that the utility model patent of ZL201120152708.0 discloses a kind of anti-corrosion type metal fiber surface combustion burner, surface combustion member wherein is tubular, this class burner can be brought into play the clean-burning advantage of metal fiber burner, but the deficiency of this surface combustion member is, be subjected to the limitation of burner overall dimensions, the combustion surfacearea of its burner member is limited, when particularly needing to strengthen combustion intensity, can bring increasing of Nox, this structure is unfavorable for the adjusting on a large scale of burning load in other words thereupon.
The utility model content
The utility model provides a kind of surface combustion member and burner head thereof for the deficiencies in the prior art.It can make the incendivity area of surface combustion burner larger in limited burner head, thereby makes burner head have wider burning load adjustable range.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of surface combustion member, comprise the tubular metal web, and it is characterized in that the barrel profile of described tubular metal web is gear shape.
The beneficial effects of the utility model are: adopting the barrel profile is the Metal Fibre Combustion member of gear shape, increase in the little situation at the burner head volume, realize the significantly raising of Metal Fibre Combustion area, can reduce combustion intensity, improve combustion stability, prolong the service life of Metal Fibre Combustion member.
On the such scheme basis, also can do following improvement.
Further, described barrel profile is the circle-arc tooth gear shape.
Further, described barrel profile is the rake tooth gear shape.
Adopt the beneficial effect of above-mentioned further scheme to be, the shape of described barrel profile can adopt multiple, and above-mentioned two kinds is commonly used.
Further, at least one side of described tubular metal web is provided with the mesh-like liner plate, and the up and down both sides of described mesh-like liner plate are provided with flange.
Adopt the beneficial effect of above-mentioned further scheme to be, adopt lining plate structure can improve the overall mechanical strength of surface combustion member.
Further, described tubular metal web is straight tube shape or cone barrel.
Adopt the beneficial effect of above-mentioned further scheme to be, can select according to the outlet size of gas-cooker purposes effects on surface combustion structure.
The utility model also provides a kind of burner head, and it comprises surface combustion member described above.
This burner head has wider firepower adjustable range.
