Overall control policy, to the SO in industrial tail gas and melting furnaces flue dust2、NOXDischarge has more strict requirements.
Glass industry is as traditional energy consumption-type industry, under the premise of energy saving requirement, in order that full combustion of fuel, very
Many glass melters have used more combustion air, i.e. coefficient of excess air, and (coefficient of excess air α is amount of actual air for combustion VaWith reason
By air capacity Va0Ratio, α=Va/Va0) it is both greater than 1.1, generally 1.1-1.3.In addition typically preheated-combustion-supporting is wanted when combustion-supporting
Air, to improve the thermal efficiency, under the double drive of high temperature and air excess, can produce substantial amounts of NO to very high temperatureXInto
In flue gas of glass melting furnace, substantial amounts of oxides of nitrogen gas, which is discharged into air, easily forms acid rain, causes environmental pollution.
Typically take flue gas of glass melting furnace NO at presentXPair the method for later regulation reduces the discharge capacity of nitrogen oxides, i.e.,
NO in flue gas of glass melting furnaceXHandled with method physically and/or chemically, to reduce NOXContent.Most common method
It is selective catalytic reduction (SCR) and SNCR method (SNCR), but no matter uses SCR
Method, or SNCR (SNCR) technology, exist in processing procedure and easily cause in ammonia leakage, catalyst
Poison, produces secondary pollution problems.In addition, taking the method for this later regulation for a long time, flue gas of glass melting furnace can be administered
Cost remains high, and glass enterprise is difficult to bear, so as to have a strong impact on the product competitiveness of glass manufacture enterprise.
A kind of glass melter gradient oxygen enriching burning-aid method and special ladder are disclosed in CN102923933A patent application

Embodiment
A pair of ports are set in existing horse shoe flame glass melter, as the combustion-supporting system of glass melter, in port
Bottom sets 2-3 branch Fuel lances, and it is small that the combustion air and fuel after being preheated during work through regenerator enter one of them together
It is well mixed in stove and occurs combustion reaction, another port is then as exhanst gas outlet.I.e. when positioned at the small of glass melter side
The combustion air of preheating is passed through when stove burns, in the side port as combustion-supporting gas entrance, the fuel in Fuel lance runs into height
The combustion air of temperature, rapid burning；The flue gas that now opposite side port is used for absorbing after burning turns into exhanst gas outlet, in flue gas
The track route for driving lower glass melter flame is in horseshoe-shape, so being horse shoe flame glass melter.Horse shoe flame glass melter
In port 15-25 minutes exchange a role, also cry and change once fiery.Because the fuel of glass melter is generally heavy oil, day combustion
Gas or producer gas, and combustion system is air refuelling, so NO in the flue gas of generationXContent is high, typically in 2000-
3000mg/Nm3。
Because existing horse shoe flame glass melter is that comparatively side charging, positive flame, therefore its bed of material length compare
Shorter, in order to strengthen fusing, the length of flame also requires that shorter, typically preferably uses short burnout.Only in this way, flame heat regulating just meeting
Glass melting area is concentrated on, plays a part of enhancing fusing position melting capacity.It is empty in existing horse shoe flame glass melter flame
Between in, the position of flame bottom always most anoxic, incomplete combustion, temperature is relatively low, therefore the utility model is in original horse shoe flame
Increase a set of pure oxygen combustion-supporting system stage by stage on glass melter newly, and using the combustion system of purity oxygen refuelling, to reduce generation
NO in flue gasXContent.At the same time, inventor find the local pure oxygen combustion-supporting of horse shoe flame glass melter be it is necessary, such as
Fruit oxygen introduces melting furnaces space with speed at an angle, and impacting flame bottom thus can be close to metal level side
One is formed containing the less oxygen-rich layer of unburned carbon granules, makes fuel combustion fully, temperature is significantly improved, and makes the temperature of flame bottom
Higher than flame top.This asymmetric flame of temperature, by vertical thermograde, one is formed in the side close to glass feed liquid
Individual height temperate zone, makes flame base increase to the heat radiation and thermal convection current inside glass feed liquid；And in the side close to furnace crown (also
It is flame top) temperature do not raise, and makes kiln top from the erosion that thus brings.Simultaneously because flame intensity increase, flame becomes
It is short, contribute to Temperature Distribution in control melting furnaces.In addition, the length of flame, can also be adjusted by controlling oxygen flow, work as oxygen flow
Increase to more than 60 m3During/h, the length of flame will be significantly shorter.Moreover, it so can also prevent from firing in regenerator
Burn, this is for heat accumulating type melting furnaces, and the life-span of regenerator lattice brick can also be improved.
Fuel is very different in general air with burning velocity in pure oxygen, and such as natural gas is in pure oxygen than aerial
Fast 10.7 times of burning velocity, therefore pure oxygen combustion-supporting, not only improve combustion intensity, moreover it is possible to accelerate burning velocity, are more beneficial for burning
Reaction is complete, can improve smoke evacuation quality, reduces the pollution of unburning material confrontation environment.
Theoretical research based on more than, the utility model is set respectively in the focus breastwork both sides of existing horse shoe flame glass melter
One pure oxygen burning spray gun, and a pure oxygen rifle is set respectively (with close to port before focus breastwork both sides, pure oxygen burning spray gun
It is rear away from port direction before direction is), the pure oxygen combustion-supporting system stage by stage of a set of new horse shoe flame glass melter is formed, its
What is sprayed in middle pure oxygen rifle is that what is sprayed in pure oxygen, pure oxygen burning spray gun is the mixture of pure oxygen and fuel.Do not changing port
In function and exposure basis, the addition of a pair of pure oxygen burning spray guns, can increasing hot spot region, (i.e. U-shaped flame is U-shaped in Fig. 1
Bottom) thermic load, so as to be conducive to the fusing of glass；Due to flame heat regulating it is too high can not effective cover glass liquid level, it is too low
Dust can then be formed, it is therefore desirable to further by the penetrating angle (30-45 °) of Reasonable adjustment pure oxygen rifle oxygen, pure oxygen rifle and
The interval (600-900mm) of pure oxygen burning spray gun and on breastwork height (with port height in same level, apart from glass
Glass ullage 200-300mm) and combustion air, fuel and oxygen sendout, flame heat regulating is concentrated on glass melting area
And focus, play a part of enhancing fusing position melting capacity.
The utility model further provides horse shoe flame glass melter on the basis of the above-mentioned system of pure oxygen combustion-supporting stage by stage
Pure oxygen combustion-supporting method stage by stage, the first stage, by reducing 10-15% combustion-supporting air quantities in port, makes fuel enter just
Imperfect combustion is carried out in melting furnaces, is now reducing environment, is unfavorable for NOXGeneration；Second stage is passed through pure in homonymy pure oxygen rifle
Oxygen, pure oxygen is complete by the fuel combustion not burnt in the flame later stage after adding, due to lacking N2Participation and burning time it is short, NOX
Growing amount seldom so that reduce generation flue gas in NOXContent.
The burning-aid method make it that whole length of flame temperature is relatively uniform gentle, is conducive to glass melting and glass melter temperature
Degree is stable, while avoiding producing NOXThermodynamic condition, so as to reduce NO in flue gas of glass melting furnaceXGeneration.
A kind of above-mentioned low NOXThe pure oxygen combustion-supporting method stage by stage of the horse shoe flame glass melter of discharge, be specially：
The left port (using the bottom in Fig. 1 as a left side, top is the right side) of horse shoe flame glass melter is first opened, while opening left pure
