Detailed description of the invention
From Fig. 1, knowable to 2, this utility model low NOx gas burner, by brazier brick 1, main body 2, altar lamp 3, annular gas
The parts compositions such as bag rifle 4, tune wind butterfly valve 5, main body 2 includes urceolus, inner core, air gun sleeve pipe and casing cover, at urceolus 22, inner core
Being provided with the fine lining 24 of pottery between 23, inner core 23 is mesh-plate structure, and casing cover 21 is fixed on inner core by support, brazier brick 1
In the ring for fixing that inner core 23 extension of main body 2 is constituted, the steady flame tube front end of altar lamp 3 uses inclined opening structure.From Fig. 3,4 can
Knowing, brazier brick 1 external diameter has the semicircle groove breach 6 inserting annular gas bag gun sprayer, and the rear end of brazier brick quirk is taper
Mouthful, front end is provided with the bank platform 7 that multiple notch combinations becomes.
As can be seen from Figure 5, annular gas bag rifle 4 is by the semicircle groove breach of the air gun sleeve pipe insertion brazier brick 1 of main body 2, ring
The gas blowout 41 of shape gas bag rifle 4 is welded in by locking nut 42 and bulb sealing section 43 lock sealing, bulb sealing section 43 docking
Gun barrel 44 front end, as can be seen from Figure 6, gas blowout 41 is provided with three grades of fuel jet orifices.Wherein primary fuel spray orifice 8 is with burner radially
Angle horizontally disposed, during work, is produced radial vortex from this fuel sprayed, as primary fuel, is ignited by altar lamp,
Play the effect of vent；Secondary fuel spray orifice 9 and burner are axial angle and radially being in tilted layout of angle, and spray from this
Fuel produces axial rotational flow, as secondary fuel；Three grades of fuel jet orifices 10 are being in tilted layout of axial angle with burner, from this
The fuel of ejection is three grades of fuel.The primary fuel of radial vortex and air mixed combustion, the flue gas of generation and axial rotational flow
Secondary fuel mixed combustion, the flue gas of generation again with three grades of fuel mixed combustions, realize the hierarchical segmented burning of fuel with this.Combustion
Material eddy flow has two effects: a wadding being the increase in air-flow moves, and enhances mixed process；Two is that the recirculating zone at eddy flow center makes
A large amount of smoke backflows the mixture with combustion gas and air mix mutually, heated mixture, improve reaction zone temperature, enhance
Chemical reaction process.A large amount of smoke backflows also reduce combustion flame surface temperature, it is suppressed that NO in flue gasXGeneration.
After this utility model main body 2 assembles with brazier brick 1, brazier brick quirk and the combination of casing cover, make air miscarriage raw
Certain deflection, increases the angle of cut of air stream and combustion gas stream, improves air-flow mixing condition, improve the air stream of porch
Speed, casing cover 21 forms the resistance shelves of bigger resistance to the air that flows through, constitutes impingement mix thus adds the wadding of air-flow and move chi
Very little, enhance the mixing of air and combustion gas, particularly with the mixing of primary fuel, the flue gas being advantageously implemented rational proportion returns
Stream.The casing cover 21 of main body 2 also has the effect of steady flame simultaneously.In burning quirk, due to the effect of casing cover, in casing cover downstream
Form a high temperature gases recirculating district, make the high temperature smoke point combustion that fuel is refluxed after shower nozzle sprays immediately, this guarantees combustion
The stability of burner burning.The pottery fibre lining being lined with between the urceolus 22 of main body, inner core 23, inner core 23 uses mesh-plate structure, energy
Effectively prevent the external heat radiation of main body, simultaneously because the damping and amortization noise reduction of web plate and liner heat-barrier material so that combustion-supporting sky
The gas noise that flow at high speed produces in burner is decayed rapidly, it is achieved the low noise discharge of burner, foot burner
During operation, noise ＜ 80dBA@1m and main body urceolus (2-2) surface temperature are less than 60 DEG C of (non-scald on hand) requirements.
The steady flame tube front end of altar lamp 3 uses inclined opening structure design.When so working, the one-level of annular gas bag gun sprayer ejection
Fuel forms the radial swirling jet of bias combustion device distance of shaft centers on distance brazier brick front end Kan Tai, and altar lamp steady flame tube front end is oblique
Mouthful design, is conducive to the most under any circumstance the igniting of primary fuel, it is achieved the stable burning of burner.
When this utility model is installed, main body 2 is fixed on body of heater by flange, and brazier brick 1 is positioned at the inner core 23 of main body 2 and stretches
Going out in the ring for fixing that part is constituted, annular gas bag rifle 4 passes through the semicircle groove breach of the air gun sleeve pipe insertion brazier brick 1 of main body 2,
Altar lamp 3 inserts at the installing hole arranged in main body 2, uses portable electronic fire rod or artificial torch to light.Its igniting side
Formula is for first lighting altar lamp, then is lighted the two-stage sparking mode of main air gun by altar lamp, it is adaptable to hot-air forced ventilation and cold
Air gravity-flow ventilation operation operating mode, can stably burn under the complex environment such as fuel pressure, change of component, reaches efficiently, saves
Energy, low NOXDisposal 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 (about 150Pa) enters split tune wind butterfly valve, according to payload, controls total blast volume, heat by split tune wind Handle of butterfly valve
Air enters body lumen, by the combination of brazier brick brazier brick quirk Yu main casing body lid, and the raw certain deflection of air miscarriage, increase
The big air stream angle of cut with combustion gas stream, improves air-flow mixing condition, improves the air velocity of porch, and casing cover 21 is right
The air that flows through forms the resistance shelves of bigger resistance, constitutes impingement mix thus adds the wadding of air-flow and move size, enhances air
With the mixing of combustion gas, particularly with the mixing of primary fuel, it is advantageously implemented the smoke backflow of rational proportion.Main body 2 is overlapped simultaneously
Lid 21 also has the effect of steady flame.In burning quirk, due to the effect of casing cover, form a high-temperature flue gas in casing cover downstream
Recirculating zone, makes the high temperature smoke point combustion that fuel is refluxed after shower nozzle sprays immediately, this guarantees the stability of burner combustion.
Meanwhile, the device fuel gas that pipeline comes enters annular gas bag from gas joint, short circuit, sprays from gas spray nozzle through gun barrel, ejection
Fuel jet from brazier brick groove indentation, there injection smoke backflow, simultaneously combustion product gases at sudden expansion reducing Kan Tai produce standing vortex
Backflow, jet injection smoke backflow and the effect of flue gas standing vortex backflow, it is achieved that the stable burning of fuel, reduce flame surface
Temperature, restrained effectively the generation of NOx in flue gas, it is achieved that the purpose of burner low NOx drainage, and the flue gas of its discharge is dense
Degree is at 80mg/Nm3Below.
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.
