Abstract
The utility model provides a reduce combustor that nitrogen oxide produced, including a burning section of thick bamboo and nozzle, the front end setting of nozzle is in the inside of a burning section of thick bamboo, and the rear end cover of nozzle is equipped with the back shroud, and the front end tip of nozzle is provided with protects the flame cup, and the front end circumference of nozzle is provided with round front end nozzle hole and round rear end nozzle hole, and the diameter in front end nozzle hole is 4.1mm, and the diameter in rear end nozzle hole is 5.2mm. The utility model provides a reduce combustor that nitrogen oxide produced improves nozzle and air inlet to the front and back proportion of adjustment oxygen has reduced nitrogen oxide's production.
Description
Technical field
The utility model relates to a kind of burner, particularly relates to a kind of burner that can reduce nitrogen oxide and produce.
Background technology
No matter conventional burners is adopt premix or diffusion combustion mode, and discharged nitrous oxides is all higher, generally between 80ppm-100ppm.The current atmosphere pollution of China is serious, greatly developing particularly along with industry in recent years, industrial discharge aggravates the pollution of environment, country also correspondingly proposes new discharge standard, the especially city such as Beijing and Shanghai, puts into effect provincial standard, require that nitrogen oxide is at 40ppm, below 30ppm stage by stage, but no matter current combustion device is combustion system or structure, all has problems, and cannot stop or reduce the reaction of nitrogen and oxygen in air.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, and provide a kind of burner reducing nitrogen oxide and produce, the concentration of adjustment oxygen, reduces the generation of nitrogen oxide.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of burner reducing nitrogen oxide and produce, comprise combustion barrel and burner, the front end of described burner is arranged on the inside of combustion barrel, the rear end of described burner is set with back shroud, the forward end of described burner is provided with protects flame cup, the front end circumference of described burner is provided with a burner hole, circle front end and a circle burner hole, rear end, and the diameter in burner hole, described front end is 4.1mm, and the diameter in burner hole, described rear end is 5.2mm.
Further, the distance of described back shroud and described combustion barrel end is 65mm.
A kind of burner reducing nitrogen oxide and produce of the utility model, improves burner and air inlet, thus the front and back ratio of adjustment oxygen, decrease the generation of nitrogen oxide.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of burner reducing nitrogen oxide and produce, comprise combustion barrel 1 and burner 2, the front end of burner 2 is arranged on the inside of combustion barrel 1, the rear end of burner 2 is set with back shroud 3, and the forward end of burner 2 is provided with protects flame cup 4, and the front end circumference of burner 2 is provided with burner hole, circle front end 5 and a circle burner hole, rear end 6, the diameter in burner hole, front end 5 is 4.1mm, and the diameter in burner hole, rear end 6 is 5.2mm.
Air is entered by combustion barrel end, and the inner chamber between combustion barrel and burner is as air duct, and combustion gas is entered by burner end, and a part of combustion gas is diffused into after air duct mixes with air by burner hole, rear end and is ignited in front end, and this part belonged to light burning; Namely another part combustion gas is ignited after directly being diffused out by the burner hole, front end of burner, and this part belongs to overrich burning.
Crossing light combustion zone, air content is very high, but temperature is lower, is unfavorable for NO_x formation; And in overrich combustion zone, even if there is very high temperature, but because air content low (namely N2 content is low), so the nitrogen oxide produced is very limited, control the generation of nitrogen oxide with this.
Therefore no matter be overrich or light burning excessively, all can reduce the generation of nitrogen oxide, by a large amount of tests, prove that the diameter when burner hole, front end is 4.1mm, when the diameter in burner hole, rear end is 5.2mm, the growing amount of nitrogen oxide is minimum.
The distance of back shroud and combustion barrel end is 65mm, and the size of this distance can control the flow of air, and to make burning complete, too small meeting causes incomplete combustion, crosses conference and reduces the thermal efficiency.
A kind of burner reducing nitrogen oxide and produce of the utility model, improves burner and air inlet, thus the front and back ratio of adjustment oxygen, decrease the generation of nitrogen oxide.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
