Description
Technical field
The utility model relates to a kind of low NO, specifically a kind of circumference type premixes water-cooled low nitrogen burning entirely
Device.
Background technique
Gas fired-boiler burning generates nitrogen oxides, and nitrogen oxides endangers atmospheric environment, generates haze, new standard requirements pot
The nitrogen oxide emission of furnace is no more than 30mg/m3.And nitrogen oxide emission depends primarily on the burner of boiler matching.It is former
There are two types of the low NOs for being first able to satisfy requirement in the market, the first is flue gas recirculation low NO, this burner
Mainly there is American-European burner producer to produce, it is expensive, and because increasing non-flammable flue gas in furnace, need bigger burner hearth
Combustion space reduces the thermal efficiency of boiler；Another is metal net surface burning low NO, the gold of this burner
Category has many micro-pores on the net, and the impurity in air blocks aperture after a period of use, needs periodic cleaning.Then mesh
Preceding to have a kind of water cooling finned tube fire row to premix low NO entirely in the market, structure includes interconnected air inlet, mixes
Channel and mixing chamber are closed, the side of hybrid channel is equipped with fuel gas inlet, even spiracular plate is equipped in mixing chamber, is installed on even spiracular plate
There is finned tube water cooling fire row, the both ends of finned tube water cooling fire row are equipped with collecting chamber, and collecting chamber is connected to finned tube water cooling fire row.
Not only high combustion efficiency, and periodic cleaning is not necessarily in operation, nitrogen oxide emission is also small.But the design of this structure there is also
Defect, the form of fire row be it is flat, flame is to carry out spray combustion to a direction, and application range is restricted, can only
It is installed in the outside of boiler, and thus will increase the volume of boiler, to increase cost, increases occupied space.
Utility model content
In view of the above-mentioned problems, to be to provide a kind of simple and reasonable circumference type entirely pre- for the problem of the utility model intends to solve
Water-cooled low NO is mixed, not only high combustion efficiency, periodic cleaning is not necessarily in operation, nitrogen oxide emission is small, and applies
Range is wider, can according to need the outside for being mounted on boiler, can also be mounted on the inside of boiler.
In order to achieve the above objectives, the utility model uses following technical scheme: a kind of circumference type premixes the low nitrogen of water-cooled entirely
Burner, including even stomata cylinder, finned tube water cooling fire row, collecting chamber, header and high temperature resistant retaining ring, outside the even stomata cylinder
Multiple porosity charts are uniformly equipped on wall from top to bottom, each porosity chart is by multiple gas evenly distributed in the circumferential direction
Hole forms, and circumferentially a circle is uniformly equipped with finned tube water cooling fire row, the fin water tube on the even stomata cylinder outer wall
The both ends of cold fire row are equipped with collecting chamber, and two collecting chambers are connected with the both ends of the finned tube water cooling fire row respectively,
The top of the even stomata cylinder is located at the collecting chamber middle position equipped with a header, the header be equipped with a combustion gas into
Mouthful, the bottom of the even stomata cylinder is located at the collecting chamber middle position equipped with a high temperature resistant retaining ring.
Effective achievement of the utility model: the utility model is simple and reasonable, equally uses full premix combustion mode, makes
The premixed gas of used time, the air and combustion gas that burn required enter in even stomata cylinder from the fuel gas inlet of header, and by even
Stomata on stomata cylinder is evenly dispersed to the surface of every finned tube water cooling fire row, is sent into hearth combustion, greatly
Efficiency of combustion is improved, is not necessarily to periodic cleaning when reducing nitrogen oxide emission, and running.Finned tube water cooling fire row both ends are respectively mounted
Have collecting chamber, cooling water flows to the other end from every finned tube water cooling fire row one end, keep finned tube water cooling fire row cooling without
It is burned, and can prevent from being tempered.Meanwhile guaranteeing outside the above feature, the utility model mainly uses even stomata cylinder,
And finned tube water cooling fire row is to enclose to arrange along even stomata cylinder outer wall one, when use flame can spray combustion around, so as to
With by the utility model be mounted on boiler internal use, solve current water cooling finned tube fire row premix low NO entirely can only
The application limitation being mounted on the outside of boiler can reduce the volume of boiler, reduce cost, reduce the occupied space of boiler.
In conclusion the utility model is simple and reasonable, not only high combustion efficiency is not necessarily to periodic cleaning, nitrogen in operation
Oxide emissions are small, and application range is wider, can according to need the outside for being mounted on boiler, can also be mounted on boiler
It is internal.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the layout drawing of even stomata cylinder and finned tube water cooling fire row in Fig. 1.
In figure: the even stomata cylinder of 1-, 2- finned tube water cooling fire row, 3- collecting chamber, 4- header, 5- high temperature resistant retaining ring, 6- gas
Hole, 7- fuel gas inlet.
Specific embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction in the present embodiment
Attached drawing, the technical solutions in the embodiments of the present invention are clearly and completely described.
As shown in Figure 1 and Figure 2, the utility model discloses a kind of circumference types to premix water-cooled low NO entirely, including even
Stomata cylinder 1, finned tube water cooling fire row 2, collecting chamber 3, header 4 and high temperature resistant retaining ring 5, on even 1 outer wall of stomata cylinder from upper and
It is uniformly equipped with multiple porosity charts down, each porosity chart is made of multiple stomatas 6 evenly distributed in the circumferential direction, even stomata
Circumferentially a circle is uniformly equipped with finned tube water cooling fire row 2 on 1 outer wall of cylinder, and the both ends of finned tube water cooling fire row 2 are equipped with
