After part is with adjusting, sprayed by different burners and friction speed, into ladle to be baked, because of the speed of each dielectric gas
Degree, volume are different, into after ladle, inhale effect from the volume of the different active forces of flue gas generation, each gas is mutually mixed and fills
Full entire ladle, in the process, coal gas and oxygen not brennschluss are burnt, and local oxygen concentration is less than 8%, even flame and disperse,
Hot spot is less in stove, is effectively protected furnace lining；
2nd, by adjusting the proportionate relationship of oxygen of fractional combustion and secondary oxygen, the length of flame and heat distribution, drop can be adjusted
The equal temperature of low flame peak value peace, can significantly avoid the formation of nitrogen oxides；
3rd, in combustion, oxygen-fuel jet of high momentum, volume suction belt are moved furnace gas, are realized in the stove of furnace gas
Cycle, promote temperature be uniformly distributed and heat transfer, by the way that combustion reaction ceaselessly occurs, until velocity attenuation disperse,
It is and completely burned off；
4th, in the case that input heat is certain, under the combustion reaction inhaled in strong volume, wider array of combustion range is obtained, entirety is heated equal
It is even, combustion peak temperature is reduced with this, hot spot is reduced and generates, low flame temperature is preferably minimized the discharge of NOx；
5th, since oxygen is instead of most of conventional combustion air, combustion process exhaust gas volumn is greatly reduced, so as to reduce flue gas
The heat loss taken away, carbon dioxide CO2 in combustion product, water H2O ratios increase, i.e., triatomic molecule ratio increases, hot spoke
It penetrates to wash one's face and rinse one's mouth and significantly improve, improve the thermal efficiency.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained without making creative work
Example is applied, belongs to the scope of protection of the invention.
The present invention provides a kind of technical solution：
A kind of novel steel ladle baking burner, including fuel burner nozzle 18, rich-oxygen nozzle 19 and burner protection tile 12, fuel burner nozzle
18 and the left and right sides of rich-oxygen nozzle 19 be equipped with burner protection tile 12,12 upside of burner protection tile is equipped with burner fastener 13, combustion
18 top of gas burner is equipped with an oxygen import 1, an oxygen import 1 connection central oxygen pipeline 2, and 2 outside of central oxygen pipeline is equipped with coal
Feed channel 14,14 top of gas piping are equipped with adjustment flange 3, and 3 both ends of adjustment flange are fixed by fixing bolt 4, gas piping
14 bottoms connection coal gas blade 15,15 bottom of coal gas blade is equipped with premixer 16, and 14 side of gas piping is equipped with gas inlet 5,
5 downside of gas inlet is equipped with combustion-supporting wind inlet 6, and combustion-supporting wind inlet 6 connects combustion-supporting wind pipeline 7, and combustion-supporting 7 left side of wind pipeline, which is equipped with, to be helped
Wind distribution pipe 8 is fired, combustion air distribution pipe 8 is connected to the circumferential weld wind pipeline 9 in rich-oxygen nozzle 19, and circumferential weld wind pipeline 9 is internally provided with
Secondary oxygen pipe 11, secondary 11 top of oxygen pipe are equipped with secondary oxygen import 10, and oxygen uptake nozzle 17 is rolled up in secondary 11 bottom of oxygen pipe connection, once
Oxygen import 1, gas inlet 5, combustion-supporting wind inlet 6 and secondary oxygen import 10 use ANSI CLASS 150# RF flanges, central oxygen
Pipeline 2, combustion-supporting wind pipeline 7, circumferential weld wind pipeline 9, secondary oxygen pipe 11 and gas piping 14 are hollow cylinder, and axle center is in same
One horizontal plane.
Operation principle：Coal gas, combustion air, oxygen pass through gas inlet, air intlet, primary oxygen import and secondary oxygen
Import after burning inside points are with adjusting, is sprayed by different burners and friction speed, into ladle to be baked, because each
Speed, the volume of a dielectric gas are different, into after ladle, inhale effect, Ge Geqi from the volume of the different active forces of flue gas generation
Body is mutually mixed and is full of entire ladle, and in the process, coal gas and oxygen not brennschluss are burnt, and local oxygen concentration is less than 8%,
Whole process is referred to as the burning of disperse formula, even flame and disperse, and hot spot is less in stove, is effectively protected furnace lining；Pass through tune
Save the proportionate relationship of oxygen of fractional combustion and secondary oxygen, the length of flame and heat distribution can be adjusted, reduce flame peak value and
Mean temperature can significantly avoid the formation of nitrogen oxides；In combustion, oxygen-fuel jet of high momentum rolls up suction belt
Dynamic furnace gas realizes cycle in the stove of furnace gas, promote temperature be uniformly distributed and heat transfer, by ceaselessly sending out
Raw combustion reaction, until velocity attenuation disperse, and it is completely burned off；It is anti-in the burning that strong volume is inhaled in the case that input heat is certain
Should under, obtain wider array of combustion range, be integrally heated evenly, combustion peak temperature is reduced with this, reduce hot spot and generate, low flame
Temperature is preferably minimized the discharge of NOx；Since oxygen is instead of most of conventional combustion air, combustion process exhaust gas volumn significantly drops
Low, so as to reduce the heat loss that flue gas is taken away, carbon dioxide CO2 in combustion product, water H2O ratios increase, i.e. three atoms
Molecular ratios increase, and heat radiation, which is washed one's face and rinsed one's mouth, to be significantly improved, and to sum up the thermal efficiency of this programme can be greatly improved.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
