Detailed description of the invention
Below according to the drawings and specific embodiments, the utility model is described in further detail:
Knowable to Fig. 1 ~ 3, this utility model ultralow NOx gas burner, by brazier brick 1, air-pressure drop sleeve pipe 2, main body
3, altar lamp 4, air gun 5, adjust the parts such as wind butterfly valve 6 composition, brazier brick external diameter 1-1 lower end is designed to teeth groove 1-3, external diameter upper end in
Frustum, quirk upper end sudden change undergauge, set horizontal U-loop groove at reducing Kan Tai, horizontal U-loop groove has lateral aperture and vertical holes,
Go directly the conical surface of frustum or upper table surface respectively.Air-pressure drop sleeve pipe 2 is made up of heat resisting pipe and end cap, is positioned at brazier brick fire
In road, and positioned by the ring for fixing of main body 3.As can be seen from Figure 4, main body 3 by top flange 3-1, main body urceolus 3-2, steel wire 3-3,
The fine 3-4 of pottery, the fine clothes-hook 3-5 of pottery, pottery fine pressing plate 3-6, base plate 3-7, peephole 3-8, fire hole 3-9, fire pot seat board 3-10, support
Muscle 3-11, gusset 3-12, ring for fixing 3-13 form.It is lined with the fine 3-4 of pottery between main body urceolus 3-2 and steel wire 3-3, uses pottery fibre
Clothes-hook 3-5 and the fine pressing plate 3-6 of pottery compresses location.
As can be seen from Figure 5, air gun 5 uses branched structure, and the collecting tubule 5-16 of air gun is by tap 5-8, metal hose even
Receive the gun barrel 5-5 of branch, then be connected respectively to main jet head 5-9 and auxiliary shower nozzle by threeway 5-4.Main jet head 5-9 is by locking
Nut 5-10 and short circuit 5-11 lock, short circuit 5-11 vertical welding with time be in charge of on 5-13, secondary be in charge of 5-13 one end pipe plug 5-12
Blocking, one end is docked with threeway 5-4 mouth；Auxiliary shower nozzle 5-1 is locked by locking nut 5-2 and short circuit 5-3, short circuit 5-3 and threeway
5-4 is direct, and main and auxiliary gas blowout head 4-1 respectively sets a fuel jet orifice, and the fuel jet orifice of the most main gas blowout head is vertically to arrange, ejection
Fuel be for primary fuel；The fuel jet orifice of auxiliary gas blowout head and being in tilted layout that burner axially makes an angle alpha, spray from this
Fuel is for secondary fuel；Adjust wind butterfly valve 6 use same main body the same noise elimination structure and low heat conductivity design.
During installation, this utility model burner is fixed on body of heater by main body 2 flange, and brazier brick 1 falls into main body 3 fire pot
On seat board 3-10, air-pressure drop sleeve pipe 2 inserts in the ring for fixing of main body 3, air gun 5 is inserted by the air gun sleeve pipe arranged in main body 3
Enter the teeth groove of brazier brick 1, the altar lamp 3 of setting, inserts at the installing hole arranged in main body 3, uses portable electronic fire rod
Or manually torch is lighted.
This utility model burner is applicable to first light altar lamp, then the two-stage sparking mode by altar lamp point gas gun,
It is applicable to hot-air forced ventilation and cold air gravity-flow ventilation operation operating mode, under the complex environment such as fuel pressure, change of component
Can stably burn, reach NO efficient, energy-conservation, lowXDisposal of pollutants and the environmental protection purpose of low noise.
During this utility model runs, combustion air preheats through device high-temperature flue gas waste heat recovery, and the heat of certain pressure is empty
Gas enters split tune wind butterfly valve, according to payload, controls total blast volume by split tune wind Handle of butterfly valve, and hot-air enters burning
Device body lumen, by by brazier brick 1 quirk and air blood pressure lowering sleeve pipe 2, brazier brick 1 external diameter teeth groove and brazier brick seat board 3-10
Dimension combination with flange 3-1 gap, cylinder top, it is achieved that the air classification of burner.The air fall arranged in brazier brick quirk
Gland pipe 2, increases the pressure drop of air travels through inlet, improves the air velocity at aditus laryngis, improves air-flow mixing condition, increases
The wadding having added air-flow moves size, enhances the mixing of air and combustion gas, and particularly the mixing of one-level combustion gas, also helps realization
The rational proportion distribution of first and second air.Pipeline come device fuel gas by air gun collecting tubule through branched pipe, tap, metal
Flexible pipe, the gun barrel of entrance branch, the main and auxiliary shower nozzle flowing to branch through threeway sprays from fuel jet orifice classification.The air of classification, point
The fuel of level produces strengthening eddy current mixing at brazier brick sudden change undergauge bank platform U-loop groove, and one-level combustion gas is ignited by altar lamp,
The flue gas produced produces standing vortex backflow at sudden change undergauge U-loop groove Kan Tai, makes one-level combustion gas be returned immediately after shower nozzle sprays
The high-temperature flue gas of stream is lighted, it is ensured that the stability of burner combustion, and the flame that one-level air mixture is formed, is at high air volume
Burn under low fuel concentration, therefore reduce flame of centre temperature, and by the multiple lateral apertures arranged at brazier brick U-loop groove and
Vertical holes sprays, and second gas burning plays the effect that secondary is ignited, and achieves the stable burning of second gas burning, two grades of mixing combustions with this
The flame that gas is formed, is to burn under low air capacity height fuel concentration, and backflow flue gas also reduces flame surface temperature.Due to
I and II combustion gas is all the mixed combustion under non-chemically equivalent proportion, and ignition temperature is low, is suppressed, when two so NOx generates
After group bias combustion is respectively completed, residue combustion gas and surplus air realize burning completely in the combination of flame top, temperature of therefore burning
Degree and oxygen concentration are the lowest, and NOx generates and is again suppressed, and the flue gas concentration of its discharge is at 60mg/Nm3Hereinafter, it is achieved thereby that
The ultra-low NOx emission of combustion product gases, has reached NO efficient, energy-conservation, lowXDisposal of pollutants and the environmental protection purpose of low noise.
Embodiment described in the utility model is only the description carrying out preferred implementation of the present utility model, not
This utility model spirit and scope are defined, on the premise of without departing from this utility model design philosophy, work in this area
Various modification that the technical solution of the utility model is made by journey technical staff and improvement, all should fall into protection of the present utility model
Scope, the technology contents that this utility model is claimed, all record in detail in the claims.
