For overcome the deficiencies in the prior art, the present invention provides a kind of high combustion efficiency, can reduce nitrogen oxides and have
The combustor for gas heating water heater of the sufficient low-nitrogen oxide discharging of burning of evil gas discharge.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of combustor for gas heating water heater of low-nitrogen oxide discharging including stent, is provided with several on the stent
Burner monolithic arranged in parallel, the burner monolithic are provided with air flue and several outlet cells connected with the air flue,
One end closing of the air flue, the other end is combi inlet port；The air flue is by the epithelium healing and downtake two that are arranged above and below
Divide and form；The cross section of the epithelium healing is gradually reduced to the back-end by front end, and the cross section of the downtake is by front end rear end
Gradually expand；The rear end of the downtake is connected with the front end of epithelium healing, the back-end closure of the epithelium healing；The gaseous mixture into
The sectional area of mouth is gradually reduced to the back-end by front end, and the rear end of the combi inlet port is connected with the downtake front end, described
The angle α that the center line of epithelium healing and the center line of downtake are formed is acute angle, and optimum is 5 °≤α≤10 °；The outlet
The lower end of unit is connected with the upside of the epithelium healing, and the outlet cell is equidistant along the length direction of the burner monolithic
Word order, the air flue height of the outlet cell are gradually reduced to the back-end by the front end of the epithelium healing.
The outlet cell is made of two rectangular openings and four round holes, and the round hole is symmetrically distributed in the rectangle
The both ends in hole, the center of circle of the round hole are located on the center line of the rectangular opening length direction；The length L of the rectangular opening,
Width W, distance S, the distance between the diameter D of round hole, the outlet cell H of two rectangular openings meet following passes in outlet cell
System：2W ＜ L ＜ 3W, W ＜ D ＜（1/2）L,（1/2）W ＜ S ＜（3/4）W,（1/2）W ＜ H ＜ L.
The beneficial effects of the invention are as follows：It is reasonable that the burner structure of the present invention is set, and combustion gas and air mixing are abundant, burning
Stablize, high combustion efficiency, the nitrogen oxide NOx and pernicious gas content in exhaust gas are low, can effectively save the energy, reduce to ring
The pollution in border.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is burner single chip architecture schematic diagram；
Fig. 3 is the top view of burner monolithic；
Fig. 4 is the sectional view of burner monolithic.
Specific embodiment
Referring to figs. 1 to Fig. 4, a kind of combustor for gas heating water heater of low-nitrogen oxide discharging, including stent 1, institute
State and several burner monolithics 2 arranged in parallel be provided on stent 1, the burner monolithic 2 be provided with air flue and with the gas
Several outlet cells of road connection（It is an outlet cell in dotted line frame in Fig. 3）, one end closing of the air flue, the other end is
Combi inlet port 4；The air flue is made of the epithelium healing 5 and 6 two parts of downtake being arranged above and below；The epithelium healing 5 it is transversal
Face is gradually reduced to the back-end by front end, and the cross section of the downtake 6 is gradually expanded to the back-end by front end；The downtake 6
Rear end is connected with the front end of epithelium healing 5, the back-end closure of the epithelium healing 5；The sectional area of the combi inlet port 4 from front end to
Rear end is gradually reduced, and the rear end of the combi inlet port 4 is connected with 6 front end of downtake, the lower end of the outlet cell with
The upside connection of the epithelium healing 5, length direction equidistant word order of the outlet cell along the burner monolithic 2,
The air flue height of the outlet cell is gradually reduced to the back-end by the front end of the epithelium healing 5, empty using the air flue of this structure
Gas and combustion gas mixing gas enter combi inlet port 4, are gradually increased by the extruding air pressure of 4 inner wall of combi inlet port, subsequently into
Air pressure continuously decreases in downtake 6, is discharged subsequently into epithelium healing 5 from outlet cell, and epithelium healing 5 is gradual to the back-end by front end
The structure that the structure of reduction and the air flue height of outlet cell are gradually reduced to the back-end by the front end of epithelium healing 5, makes each outlet list
The air pressure in first exit is consistent substantially, can realize stable burning.
The angle α that the center line Oa of the epithelium healing 5 and the center line Ob of downtake 6 are formed is acute angle, in the present embodiment
In, 5 °≤α≤10 °, if angle is too small or excessive, 6 junction of epithelium healing 5 and downtake can be made（Corner）Resistance occur
Larger variation can change the differential pressure in epithelium healing 5 and downtake 6（Air pressure during burning in epithelium healing 5 is slightly below downtake 6
Interior air pressure）, influence the effect burnt.
The outlet cell is made of two rectangular openings 3 and four round holes 6, and the round hole 6 is symmetrically distributed in described
The both ends of rectangular opening 3, the center of circle of the round hole 6 are located on the center line of 3 length direction of rectangular opening；The rectangular opening 3
Length L, width W, distance S, the distance between the diameter D of round hole 6, the outlet cell H of two rectangular openings 3 in outlet cell
Meet following relations：2W ＜ L ＜ 3W, W ＜ D ＜（1/2）L,（1/2）W ＜ S ＜（3/4）W,（1/2）W ＜ H ＜ L, using it is this not
Evenly distributed air outlet structure makes there are small pressure differential on combustion front, and it is micro- that this small pressure differential can generate flame
Small fluctuation, is more conducive to the circulation of air-flow, and burning is more abundant.
Above embodiment cannot limit the protection domain of the invention, and the personnel of professional skill field are not departing from
In the case of the invention general idea, the impartial modification and variation done still fall within the scope that the invention is covered
Within.
