Description
Technical field
The utility model is related to petroleum refining equipment technical fields, and in particular to the reduction burning used in Furnace
The burner of device nitrogen oxides and carbon monoxide emission.
Background technology
The main structure for the low NO that existing Petrochemical Enterprises Furnace uses is：Center rifle and side rifle position
Fixation is set, can not be slided up and down, and the allocation proportion of center rifle and side rifle fuel is fixed, it is unadjustable.
The hidden danger that the fixed structure of center rifle and side rifle is brought is the debugging of inconvenient burner, burner checking maintenance stage
Center rifle and side rifle change.In addition, debugging the stage in burner, the exceeded problem of nitrogen oxides, carbon monoxide emission is encountered
When, said burner is helpless.
The load regulation rate of traditional low NO is 5:1, burner is run under very low or very high load can not
It realizes.Traditional adaptable fuel element of low NO is relatively narrow, but the fuel gas of domestic refinery is mostly complicated and changeable, sometimes
Hydrogen-enriched fuel gas is burnt, low hydrogen-containing fuel gas is burnt sometimes, does not adapt to the changeable situation of fuel element.
Utility model content
In view of this, the utility model provides a kind of burner of low-nitrogen oxide discharging, burner can be facilitated
Debugging, burner checking maintenance stage center rifle and side rifle change, and can improve load regulation rate and the enhancing of burner
The fuel tolerance of burner.
A kind of burner of low-nitrogen oxide discharging, the burner include center rifle, side rifle, altar lamp, shell and bottom plate,
The center rifle, side rifle and altar lamp are slidably matched with the adjusting sleeve being fixedly connected on bottom plate respectively, pass through clamping screw
It is fixed on and adjusts in sleeve, realize that the distance of short transverse is adjusted；The center rifle and side rifle pass through hose and center rifle respectively
Inlet suction port is connected with side rifle inlet suction port, and altar lamp connects altar lamp inlet suction port, and altar lamp inlet suction port is connect by hose
Lead to external air source, center rifle inlet suction port and side rifle inlet suction port are connect with main gas valve, mounting ball valve point on main gas valve
The air inflow of center rifle and side rifle Kong Zhi not entered.
Further, the center rifle and altar lamp are located at the inside of fire pot in furnace body, and the side rifle position is in the outer of fire pot
Side.
Further, the bottom of the shell connects shield, and side rifle inlet suction port is fixedly connected on the bottom of shield, center
Rifle inlet suction port and altar lamp inlet suction port pass through shield by via, hose pass through shield connect while rifle inlet suction port and while
Rifle.
Advantageous effect：
1, the utility model facilitates burner to debug, and burner debugs the stage, and it is super to encounter nitrogen oxides, carbon monoxide emission
When target problem, allocation proportion of the fuel between center rifle and side rifle can be adjusted, reduces nitrogen oxides and carbon monoxide emission.
Such as there is the exceeded situation of discharged nitrous oxides, center rifle fuel ratio can be reduced, increase side rifle fuel ratio, allowed more
Fuel disperses combustion on the rifle of side, to reduce discharged nitrous oxides.Such as there is the exceeded situation of carbon monoxide emission, Ke Yizeng
Add center rifle fuel ratio, reduce side rifle fuel ratio, allows more multi fuel in center rifle concentrated combustion, to reduce carbon monoxide
Discharge.
2, the utility model can improve the load regulation rate of burner, and the load regulation rate of traditional low NO is 5:1,
5 can be increased to by adjusting ratio using the utility model:1 or more.Because of the air inlet pipeline of the center rifle and side rifle of the utility model
Upper to be mounted with ball valve respectively, i.e. the fuel of center rifle and side rifle can be separately adjustable, if burner is needed in very low load
Lower operation (the 1/5 or less of burner maximum heating load), can close the ball valve of side rifle, only open center rifle ball valve, in this way
Fuel only in center gun burner, if burner need under very high load operation (5 times of burner minimum thermic load with
On), center rifle ball valve can be turned down, side rifle ball valve is opened greatly, fuel more in this way are in side rifle disperses combustion.
3, the fuel tolerance of the utility model energy strengthen burning device, traditional adaptable fuel element of low NO compared with
It is narrow, but the fuel gas of domestic refinery is mostly complicated and changeable, burns hydrogen-enriched fuel gas sometimes, burns low hydrogen-containing fuel gas sometimes.This reality
With the novel fuel gas for being adapted to different hydrogen contents.If burning hydrogen-enriched fuel gas, the flame temperature of hydrogen-enriched fuel gas is high, is easy
Nitrogen oxides is generated, center rifle ball valve at this moment can be turned down, open big side rifle ball valve, reduces center rifle fuel ratio, increase side rifle
Fuel ratio, to reduce the discharged nitrous oxides of hydrogen-rich fuel；If burning low hydrogen-containing fuel gas, the flame of low hydrogen-containing fuel gas
Temperature is low, easy tos produce carbon monoxide, at this moment can open big center rifle ball valve, turn down side rifle ball valve, increases center rifle fuel ratio
Example reduces side rifle fuel ratio, allows more fuel in center rifle concentrated combustion, reduces carbon monoxide emission.
