Description
Technical field
The present invention relates to petroleum refining equipment technical field, and in particular to the reduction burner nitrogen used in Furnace
The burner of oxide 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 put, 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, nitrogen oxides is run into, the problem of carbon monoxide emission is exceeded
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
Realize.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, burns low hydrogen-containing fuel gas sometimes, it is impossible to adapt to the changeable situation of fuel element.
The content of the invention
In view of this, the present invention provides a kind of burner of low-nitrogen oxide discharging, can facilitate burner debugging,
Burner checking maintenance stage center rifle and side rifle change, and can improve the load regulation rate and strengthen burning device of burner
Fuel tolerance.
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, the regulating sleeve of side rifle and altar lamp respectively with being fixedly connected on bottom plate are slidably matched, and pass through clamping screw
It is fixed in regulating sleeve, realizes 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 connection altar lamp inlet suction port, altar lamp inlet suction port is connect by hose
Lead to exterior source of the gas, center rifle inlet suction port and side rifle inlet suction port are connected 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 connection shield of the housing, side rifle inlet suction port are fixedly connected on the bottom of shield, center
Rifle inlet suction port and altar lamp inlet suction port pass through shield by via, hose through shield connect while rifle inlet suction port and while
Rifle.
Beneficial effect：
1st, the present invention facilitates burner to debug, and in the burner debugging stage, it is exceeded to run into nitrogen oxides, carbon monoxide emission
During 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, increase side rifle fuel ratio can be reduced, allow more multi fuel
The disperses combustion on the rifle of side, so as to reduce discharged nitrous oxides.Such as there is the exceeded situation of carbon monoxide emission, in can increasing
Heart rifle fuel ratio, reduce side rifle fuel ratio, allows more multi fuel in center rifle concentrated combustion, so as to reduce carbon monoxide row
Put.
2nd, the present invention can improve the load regulation rate of burner, and the load regulation rate of traditional low NO is 5:1, use
The present invention, which adjusts ratio, can bring up to 5:More than 1.Because it is mounted with respectively on the center rifle of the present invention and the air inlet pipeline of side rifle
Ball valve, the i.e. fuel of center rifle and side rifle can be separately adjustable, if burner needs to run (burner under very low load
Less than the 1/5 of maximum heating load), the ball valve of side rifle can be closed, only open center rifle ball valve, such fuel is only in center rifle
Burning, can be by center rifle if burner needs to run (more than 5 times of burner minimum thermic load) under very high load
Ball valve turns down, side rifle ball valve is opened greatly, and so more fuel are in side rifle disperses combustion.
3rd, the fuel tolerance of present invention energy strengthen burning device, traditional adaptable fuel element of low NO is relatively 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.The present invention can
To adapt to the fuel gas of different hydrogen contents.If burning hydrogen-enriched fuel gas, the flame temperature of hydrogen-enriched fuel gas is high, easily produces nitrogen oxygen
Compound, at this moment can turn down center rifle ball valve, open big side rifle ball valve, reduce center rifle fuel ratio, increase side rifle fuel ratio,
So as to reduce the discharged nitrous oxides of hydrogen-rich fuel；If burning low hydrogen-containing fuel gas, the flame temperature of low hydrogen-containing fuel gas is low, holds
Carbon monoxide is also easy to produce, big center rifle ball valve at this moment can be opened, turn down side rifle ball valve, increase center rifle fuel ratio, reduce side
Rifle fuel ratio, allows more fuel in center rifle concentrated combustion, reduction carbon monoxide emission.
