Abstract
The invention discloses a gas burner, which comprises a gas shell, a gas pipe communicated with the gas shell, and an air shell arranged at the periphery of the gas pipe in a surrounding way. The front end of the gas pipe is provided with an electrode used for ignition; the front end of the gas pipe is provided with a combustion chamber; the electrode is positioned in the combustion chamber; the rear end of the combustion chamber is connected with the front end part of the gas pipe through a wind disk; the combustion chamber is communicated with the air shell; the front end of the combustion chamber is provided with a shrunken flame nozzle; the periphery of the combustion chamber is sleeved with an outer pipe communicated with the air shell; and the front end of the outer pipe is provided with an annular combustion-supporting wind nozzle along the periphery of the flame nozzle. The gas burner has the advantages of performing two-stage combustion, combusting the gas fully, and making the energy conversion rate of the system high. The flame temperature field is more uniform and facilitates heat energy utilization; the smoke at the smoke outlet has high speed; and the emission of NOx in the smoke is less than 150ppm, so the environment is protected.
Description
Technical field
The present invention relates to a kind of parts of burner of industrial heating gas stove, particularly a kind of fuel burner nozzle.
Background technology
The burner of the burner of existing industrial furnace all is the burner of one-level burning, because the defective of its structure; Make its combustion gas only pass through primary combustion, thereby make that the burning of combustion gas is insufficient not exclusively, influence the energy conversion rate of system; The flame temperature field of burner is also inhomogeneous, and stack gas exit velocity is not high, and the NOx discharge capacity in the smoke components is big; Contaminated environment, even influence the work of system.
Summary of the invention
In order to address the above problem, the burning that the object of the present invention is to provide a kind of secondary firing, combustion gas cmpletely, the high fuel burner nozzle of energy conversion rate of system.
The present invention solves the technical scheme that its problem adopts: a kind of fuel burner nozzle; Comprise combustion gas housing, the Gas Pipe that is connected with the combustion gas housing, around being arranged at the peripheral air housing of Gas Pipe, the front end of Gas Pipe is provided with the electrode that is used to light a fire, the front end of said Gas Pipe is provided with a combustion chamber; Electrode is positioned at the combustion chamber; The rear end of combustion chamber is connected with the leading section of Gas Pipe through a wind dish mutually, and the combustion chamber is connected with the air housing, and the front end of combustion chamber is the flame jet that dwindles; The outer race of said combustion chamber is provided with the outer tube that is connected with the air housing, and the front end of outer tube is provided with the combustion air nozzle of an annular around the periphery of flame jet.
Technique scheme also can have following improvement project: the leading section of said Gas Pipe also be provided with one be used to adjust the combustion chamber front and back position the combustion chamber adjusting device; The inboard of said air housing also is provided with the fiber liner.
The invention has the beneficial effects as follows: owing to be provided with a combustion chamber at the front end of Gas Pipe, the outer race of combustion chamber is provided with outer tube, ejection combustion air body in the outer tube; Make from the flame of flame jet ejection and further burn; Like this, carry out the one-level burning in the combustion chamber, before the combustion air nozzle of annular, carry out secondary firing; Make the abundant completing combustion of combustion gas, thus the present invention be a kind of burning of having carried out secondary firing, combustion gas cmpletely, the energy conversion rate high fuel burner nozzle of system.Because flame combustion of the present invention cmpletely, so the flame temperature field of burner is more even, helps the utilization of heat energy; And stack gas exit velocity is very high, and the NOx discharge capacity in the smoke components is little, and NOx discharges less than 150ppm; Free from environmental pollution, environmental protection can not influence the work of system yet.Compact conformation of the present invention, safe and reliable, be easy to safeguard.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is a structure cutaway view of the present invention.
The specific embodiment
With reference to Fig. 1; A kind of fuel burner nozzle of the present invention; Comprise combustion gas housing 1, the Gas Pipe 5 that is connected with combustion gas housing 1, around being arranged at the peripheral air housing 3 of Gas Pipe 5, the front end of Gas Pipe 5 is provided with the electrode 8 that is used to light a fire, the front end of said Gas Pipe 5 is provided with a combustion chamber 6; Electrode 8 is positioned at combustion chamber 6; The rear end of combustion chamber 6 is connected with the leading section of Gas Pipe 5 through a wind dish 4 mutually, and combustion chamber 6 is connected with air housing 3, and the front end of combustion chamber 6 is the flame jet 61 that dwindles; The outer race of said combustion chamber 6 is provided with the outer tube 7 that is connected with air housing 3, and the front end of outer tube 7 is provided with the combustion air nozzle 71 of an annular around the periphery of flame jet 61.
Technique scheme also can have following improvement project: the leading section of said Gas Pipe 5 also be provided with one be used to adjust the combustion chamber front and back position combustion chamber adjusting device 9; The inboard of said air housing 3 also is provided with fiber liner 2.
Operation principle of the present invention: combustion gas is got into by combustion gas housing 1; The combustion gas kind can be natural gas, liquefied gas, town gas, coke-stove gas, high burnt gaseous mixture, producer gas etc.; Combustion air is got into by air housing 3; The combustion air temperature spends-20+650 degree scopes in, but operate as normal all.Combustion gas enters in the burner internal combustion chamber 6 through Gas Pipe 5; In the combustion chamber, accomplish the one-level burning, the one-level combustion air is by passing through between combustion chamber 6 and the wind dish 4, and air quantity approximately is 10～50% of total air feed; The flue gas that the one-level burning produces is through flame jet 61 ejections of combustion chamber 6; This moment, so belong to imperfect combustion, flame temperature was between 600～1000 degree owing to the air quantity of combustion air volume far fewer than normal need.The secondary combustion air is promptly participated in burning in the combustion air nozzle 71 ejection backs of annular from the circumferential weld between combustion chamber 6 and the outer tube 7, and unburnt flue gas is realized completing combustion at this and secondary combustion air.
The present invention has only one the tunnel to supply combustion air and a tunnel to supply combustion gas, realizes the one-level burning in the inside of burner through the combustion chamber, after having gone out the combustion chamber, realizes secondary firing with combustion air again.Advantage is at an inner stable one-level combustion flame, the stable secondary firing flame of formation behind spout then of forming of burner.When combustion air serviceability temperature scope spend-20+650 degree scopes in the time, but this serial burner operate as normal all.
The present invention compares with the burner that conventional one-level is burnt, and the flame temperature field of this burner is more even, and stack gas exit velocity is very high, can reach 160 meters of per seconds.Simultaneously, owing to adopted the multistage combustion technology, the NOx discharging in the smoke components is less than 150ppm.
The present invention is mainly used on the combustion gas stove of various heat treatments and heating, be a efficiently, at a high speed, the combustion apparatus of energy-conservation low NOx drainage.The serviceability temperature of combustion air is the highest can to reach 650 degree.
In addition, the present invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
