The promotion that NOx emission requires, crude fuel furnace have been unsatisfactory for requiring.Due to passing through installation when fuel burns in industrial fuel furnace
It is completed on burner on industrial furnace, thus the performance of burner is directly related to the NOx emission of industrial furnace fuel.Pass through
The burner on industrial fuel furnace is improved to reduce NOx emission be feasible.
Summary of the invention
The purpose of this utility model is to provide the gas burner on a kind of industrial fuel furnace, burner structure letters
It is single, it is easy to maintenance, there is no specific size requirement, last flue gas emission NOX < to the burner hearth space of industrial fuel furnace
58mg/m3。
The technical solution adopted in the utility model is: a kind of ultralow nitrogen discharged gas burner, including burner body,
Be characterized in that: the burner body is a single cylindrical body, bellows is equipped in single cylindrical body, combustion gas distributes packet, exhaust gas nozzle, sky
Gas repeated dispensing device, combustion gas repeated dispensing device, overheavy firing room, the one of single cylindrical body are terminated with gas pipeline and air pipeline,
The gas pipeline and combustion gas distribution packet are connected, and combustion gas distribution packet is hollow structure inside, and combustion gas, which distributes, wraps that be connected to combustion gas more
Sub-distribution device, the combustion gas repeated dispensing device are more and are arranged in parallel and arrange the exhaust gas nozzle circularized, the exhaust gas nozzle
Second half section on the gas jet orifice of adjustable tolerance size is distributed with, the opening of the gas jet orifice is on overheavy firing locular wall；
The air pipeline is connected with bellows, and the bellows are connected to air repeated dispensing device, and the air repeated dispensing device is that combustion gas is more
Air jet orifices, the air spray are distributed on air repeated dispensing device for space outside the second half section of the exhaust gas nozzle of sub-distribution device
The opening in hole is on overheavy firing locular wall.
The combustion gas distribution packet of the utility model is fired with exhaust gas nozzle, air repeated dispensing device, combustion gas repeated dispensing device, reinforcing
It burns room and welds integral, bellows individualism.
The air jet orifices and gas jet orifice of the utility model use concentric circle holes structure, and the air jet orifices are in gas jet orifice
Outside.
The gas jet orifice is to be equally spaced.
The innovation of the utility model key is: 1, having carried out segmentation burning to flame by gas jet orifice.2, strengthening combustion
Burn indoor carry out flue gas recirculation utilization.3, bias combustion.So as to which flame to be divided to many small torches under oxygen deprivation situation, fire
The flue gas that the flame of burner root generates is blended into inside 2 air, then is burnt with remaining combustion gas, so that each small fire
The temperature that torch generates is radiated rapidly, and control flame in this way makes flame temperature low, thus the NO of generationXDischarge can be very low.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model；
Fig. 2 is the combustion gas and air flow figure of the utility model；
In figure, 1, air pipeline；2, bellows；3, air repeated dispensing device；4, gas pipeline；5, combustion gas distribution packet；6, it fires
Gas repeated dispensing device；7, overheavy firing room.
Specific embodiment
The utility model is described further below according to the drawings and specific embodiments:
Each modular construction of the utility model is to be individually present, using fractionation combination connection between each component, and in sky
Giving air and combustion gas mixing in proportion between gas repeated dispensing device and combustion gas distribution packet, there are enough spaces, and this is practical new
Type structure unifies air and combustion gas into same channel overheavy firing room, and completes second-time burning in overheavy firing room, excellent
Having changed other universal low NOs must first allow combustion gas and air to enter in burner hearth or dedicated combustion chamber just to can be carried out and match again
Than the process of burning, thus the utility model structure just sufficiently meet user when burning is completed and enters equipment needed for environment
Requirement has achieved the purpose that energy-efficient to subtract consumption in corresponding situation in advance.
The structure and arrangement of features of the utility model is further illustrated below:
From fig. 1, it can be seen that a kind of ultralow nitrogen discharged gas burner of the utility model, including burner body, the burning
Device main body is a single cylindrical body, be equipped in single cylindrical body bellows 2, combustion gas distribution packet 5, exhaust gas nozzle, air repeated dispensing device 3,
Combustion gas repeated dispensing device 6, overheavy firing room 7, the one of single cylindrical body are terminated with gas pipeline 4 and air pipeline 1, the fuel gas conduit
Road is connected with combustion gas distribution packet, and combustion gas distribution packet is hollow structure inside, and combustion gas distribution, which is wrapped, is connected to combustion gas repeated dispensing device, institute
It states combustion gas repeated dispensing device and is arranged in parallel and arranges the exhaust gas nozzle circularized for more, divide on the second half section of the exhaust gas nozzle
It is furnished with the gas jet orifice of adjustable tolerance size, the opening of the gas jet orifice is on overheavy firing locular wall；The air pipeline
It is connected with bellows, the bellows are connected to air repeated dispensing device, and the air repeated dispensing device is the combustion of combustion gas repeated dispensing device
The air jet orifices of adjustable tolerance size, the sky are distributed on air repeated dispensing device for space outside the second half section of gas blowout pipe
The opening of gas spurt is on overheavy firing locular wall.The air jet orifices and gas jet orifice of the utility model use concentric circle holes structure,
The air jet orifices are outside gas jet orifice.
The all parts of the utility model burner use welding fabrication entirely, and integral product appearance is in monomer cylindrical type, entirely
Without tape member outside complexity, shape is simple and beautiful, practical；The combustion gas distribution packet set in simultaneously is multiple with exhaust gas nozzle, air
Distributor, combustion gas repeated dispensing device, overheavy firing room all pass through welded connecting into an entirety, bellows individualism.
As can be seen from Figure 2, for combustion air by air pipeline 1, bellows 2 enter air repeated dispensing device 3, from air jet orifices into
Enter overheavy firing room 7.Combustion gas enters the gas jet orifice that combustion gas distribution packet 5 is assigned to combustion gas repeated dispensing device 6 by gas pipeline 4
Into overheavy firing room 7, after combustion gas enters overheavy firing room by respective spray orifice with air, combustion gas is first carried out with partial air
Burning, the flue gas of generation of burning have burnt with no again after being mixed with 2 air of air repeated dispensing device distribution
Combustion gas is mixed and burned, and since each small torch has certain spacing, the high temperature of generation is cooling by the dilute heat of 2 air, 2 skies
Gas with remaining combustion gas due to carrying out 2 burnings after having blended flue gas again, so that the flame temperature of entire combustion process obtains
Control is arrived, therefore high temperature generates NOX and accordingly controlled.
