Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
Accompanying drawing, the technical scheme of the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is this hair
Bright part of the embodiment, rather than whole embodiments.Based on described embodiments of the invention, ordinary skill
The every other embodiment that personnel are obtained on the premise of without creative work, belongs to the scope of protection of the invention.
As shown in figs. 1-11, a kind of low nitrogen combustion apparatus, including the burner 1 with combustion chamber, the burning of burner
Chamber circular chamber, naturally it is also possible to which to be square etc., one end of burner is upstream end 2, is fired so that fuel gas enters
Burn in chamber and burnt, the other end is outlet side 3, for the gas discharge after combustion chamber Indoor Combustion, is set in burner
Igniter 4 is equipped with, igniter can use any money device used by current combustion device, be selected with specific reference to needs
Select；Close upstream end is primary combustion zone 5 in combustion chamber, passes through igniter into the fuel gas in combustion chamber
Igniting after, first burnt in primary combustion zone.The rear in primary combustion zone forms second-time burning in combustion chamber
Area 6, the ignition temperature in combustion chamber is not higher than 1500 DEG C, with the NOx avoided generation.
In order to lift after-flame and efficiency of combustion of the fuel gas in intermediate zone, in intermediate zone at least provided with
There is one group to make to enter the air register counterclockwise 7 that gas in the combustion zone forms turn counterclockwise, and one group makes gas form up time
The air register clockwise 8 of pin turn；Air register counterclockwise is placed in air register front or behind clockwise.When setting two or two
When air register counterclockwise above and air register clockwise, air register counterclockwise is disposed on combustion chamber with air register clockwise
In room, as shown in Fig. 4/5, four air registers form arranged for interval.The fuel gas entered from upstream end passes through air distribution counterclockwise
Enter after device in air register clockwise, or enter after air register clockwise in air register counterclockwise.With specific reference to needs
Carry out selection setting.
The concrete structure of air register counterclockwise is described below：Air register counterclockwise includes the inverse time of multiple straight sheets
The inwall of burner 1 is fixed in pin cloth wind piece 9, one end of cloth wind piece counterclockwise, and the other end is hanging；The free end of cloth wind piece counterclockwise
Between enclose center-aisle 10 (such as Fig. 8 is shown), or free end is fixedly connected on a circular discs 11 jointly (such as Fig. 9 is shown)
Periphery wall, by the setting of circular discs, first, the bonding strength of increase cloth wind piece, two enter fashionable when fuel gas, can hit
Hit and disperseed in circular discs to surrounding, increase the impact between gas with mixing；Being fixedly connected here can use weldering
Connect, bolt etc. is conventional is fixedly connected with mode.Multiple inner circumferentials of the cloth wind piece counterclockwise along burner form arranged for interval, often
Being formed radially of individual plane where cloth wind piece counterclockwise and burner is in tilted layout (such as included angle A is shown) and adjacent cloth wind counterclockwise
Piece is not equal to 0 ° and 90 ° and 180 ° towards equidirectional inclination, above-mentioned included angle A, i.e., plane where cloth wind piece counterclockwise not with combustion
The radial and axial coincidence of burner；Each cloth wind piece counterclockwise has inner side wind distributing face 12 and outside wind distributing face 13, counterclockwise
The cloth wind passage of wind-guiding counterclockwise is formed between the outside wind distributing face of cloth wind piece and the adjacent inner side wind distributing face of cloth wind piece counterclockwise
14, so that fuel gas is by forming water conservancy diversion.
Here the arrangement of cloth wind piece and burner inner wall counterclockwise, there are two kinds, one kind is cloth wind piece institute counterclockwise
In plane perpendicular to burner inner wall (such as Fig. 7 is shown)；Another kind is：Planar tilt is in burner where cloth wind piece counterclockwise
Wall is arranged (such as Fig. 2/8/9 is shown), and such air register increases in the length of cloth wind, i.e., whole ventilation terminal counterclockwise is in cone
Shape, add cloth wind energy power；, can ventilation terminal can be by the more courts of the gas of entrance counterclockwise when using this kind of mode
Burner internal peripheral direction and carry out wind-guiding, and ventilation terminal can will enter cloth clockwise when using this kind of mode clockwise
Gas in wind device more carries out wind-guiding towards the middle part in burner, passes through the cloth wind clockwise, counterclockwise of this spline structure
Device can accelerate disturbance between gas with mixing, the reaction efficiency between lift gas.
And ventilation terminal includes the cloth wind piece 15 clockwise of multiple sheets, cloth wind piece clockwise and cloth wind counterclockwise clockwise
The arranged direction of piece is opposite.Only it is arranged direction difference because ventilation terminal clockwise is identical with the structure of ventilation terminal counterclockwise, its
Concrete structure just seldom repeats herein.
Also include being used for a gas-distributing fan 16 for carrying out primary combustion zone air distribution, the output end of a gas-distributing fan extends to
In primary combustion zone.The air distribution chamber 17 of annular is formed in second-time burning section outside burner, and into air distribution chamber
The secondary gas-distributing fan 18 of air-supply, connection air distribution chamber and the wind distributing hole 19 of intermediate zone are distributed with the burner；Air distribution chamber
Indoor wind is entered into intermediate zone by wind distributing hole around intermediate zone；The wind entered from wind distributing hole passes through air distribution
The air distribution of device mixes with fuel gas, accelerates the burn-off rate and efficiency of combustion of fuel gas.
