S1/S2=0.20~0.40.
In other words, burner can include one or more fuel element 1, for example, burner can include multiple combustions
Unit 1 is burnt, multiple fuel elements 1 are arranged side by side and are arranged along the width of fuel element 1.The width is i.e. such as Fig. 5
With the left and right directions shown in Fig. 7.Each fuel element 1 includes burner shell 11 and fairing 14, and fairing 14 is located at
In burner shell 11.
The first dense combustion chamber 1111, the second dense combustion chamber 1121 and light combustion chamber 1141 are limited in burner shell 11,
Burner shell 11 is equipped with dense burning injection entrance 131, light burning injection entrance 121, the first dense burning-flame port 118, second
Dense burning-flame port 119 and light burning opening 115, dense burning injection entrance 131 are used for dense burning and introduce air, and light burning injection enters
Mouth 121 is used for light burning and introduces air, and with reference to shown in Fig. 1-Fig. 3 and Fig. 6, dense burning injection entrance 131 is located at light burning and draws
The top of entry portal 121.
Dense burning injection entrance 131 is connected with the first dense 1111 and second dense combustion chamber 1121 of combustion chamber respectively, and first is dense
Combustion chamber 1111 is connected with the first dense burning-flame port 118, and the second dense combustion chamber 1121 is connected with the second dense burning-flame port 119, light
Burning injection entrance 121 is connected with light combustion chamber 1141 and light combustion chamber 1141 is connected with light burning opening 115.
In this way, air is introduced from dense burning injection entrance 131, and with forming dense burning gases after combustion gas mixing, after mixing
Dense burning gases can respectively enter the first dense 1111 and second dense combustion chamber 1121 of combustion chamber, and respectively lead to the first dense burning
118 and second dense burning-flame port 119 of hungry ghosts who spit fire.Light burning is formed after air and combustion gas mixing that light burning injection entrance 121 introduces
Gas, and flow to light combustion chamber 1141.With reference to shown in Fig. 5-Fig. 8, fairing 14 is located in light burning opening 115, rectification dress
Put 14 and be equipped with multiple light burning-flame ports 141, light combustion chamber 1141 is connected with multiple light burning-flame ports 141 respectively, light combustion gas
Body can lead to multiple light burning-flame ports 141.
With reference to shown in Fig. 4, Fig. 5, Fig. 7 and Fig. 8, the first dense 118 and second light burning-flame port 141 of burning-flame port is respectively provided at
The both sides of light burning opening 115, multiple light burning-flame ports 141 are located at the first dense 118 and second dense burning-flame port 119 of burning-flame port
Between, in this way, it is light burning-flame port 141 that centre can be formed on the top of each fuel element 1, both sides are the knot of dense burning-flame port
Structure.That is, fuel element 1 can form middle light flame, the flame structure of the dense flame in both sides, so as to improve in burning
The stability of flame, reduces combustion flame temperature, achievees the purpose that to control nitrogen oxides in effluent discharge.
Wherein, the cross-sectional area of dense burning injection entrance 131 is S1, and the cross-sectional area of light burning injection entrance 121 is S2,
S1 and S2 can meet：S1/S2=0.20~0.40, that is to say, that the cross-sectional area S1 of dense burning injection entrance 131 is light combustion
Burn the cross-sectional area S2 of injection entrance 121 0.20~0.40 times.Thus, dense burning injection entrance 131 and light burning be can control
The air capacity that injection entrance 121 introduces, and cause the air that is introduced from dense burning injector 13 entrance and from light burning injection
The air that 12 entrance of device introduces forms good mixed proportion with combustion gas respectively, to control the primary air of dense burning or light burning
Rate, the primary air rate are the ratio of the air capacity and gas quantity when combustion gas and air are pre-mixed, and are fired completely with combustion gas
Burn the theoretical air requirement of reaction and the ratio of fuel quantity AIR Proportional.So as to effectively improve the stability of flame structure, with into
One step reduces the discharge of nitrogen oxides in effluent, reduces environmental pollution.
Thus, burner according to embodiments of the present invention, the first dense 118 and second dense combustion of burning-flame port of fuel element 1
The both sides that hungry ghosts who spit fire 119 is located at multiple light burning-flame ports 141 respectively are burnt, middle for light combustion flame to be formed, both sides are dense burning
The stabilization flame structure of flame, reaches reduction flame temperature, the purpose that nitrogen oxides in effluent discharges after control burning.Wherein fire
The cross-sectional area S1 of the dense burning injection entrance 131 of burner and the cross-sectional area S2 of light burning injection entrance 121 meet：S1/S2
=0.20~0.40, so that the air that dense burning injection entrance 131 and light burning injection entrance 121 introduce is formed with combustion gas
Good ratio, further to control the structural stability of combustion flame, reduces the discharge of nitrogen oxides.
In some embodiments of the invention, can be limited respectively between the two side of fairing 14 and light burning opening 115
The first sidewalk for visually impaired people 116 and the second sidewalk for visually impaired people 117 are made, the first sidewalk for visually impaired people 116 is located at the first dense burning-flame port 118 and multiple light burning-flame ports
Between 141, the second sidewalk for visually impaired people 117 is between the second dense burning-flame port 119 and multiple light burning-flame ports 141.Such as Fig. 7 and Fig. 8 institutes
Show, fairing 14 is located at light burn and is open in 115 and is connected with the two side of light burning opening 115, and divides with two side walls
The first sidewalk for visually impaired people 116 and the second sidewalk for visually impaired people 117 are not limited, and the first sidewalk for visually impaired people 116 and the second sidewalk for visually impaired people 117 do not connect with light combustion chamber 1141
It is logical.First dense burning-flame port 118 and multiple light burning-flame ports 141 can be spaced apart by the first sidewalk for visually impaired people 116, pass through the second sidewalk for visually impaired people
117 can be spaced apart the second dense burning-flame port 119 and multiple light burning-flame ports 141, so that may be such that flame structure is more stablized,
The effectively discharge of control nitrogen oxides in effluent.
Alternatively, as shown in figure 8, the top surface of the top surface of the lateral wall of the first sidewalk for visually impaired people 116 and the lateral wall of the second sidewalk for visually impaired people 117
Top surface concordant and higher than fairing 14, the top surface of the lateral wall of the first dense burning-flame port 118 and the second dense burning-flame port 119
Lateral wall either flush and higher than the first sidewalk for visually impaired people 116 lateral wall top surface and the second sidewalk for visually impaired people 117 lateral wall top surface,
The top surface of the top surface of the lateral wall of first sidewalk for visually impaired people 116 and the lateral wall of the second sidewalk for visually impaired people 117 respectively with the top surface of fairing 14
Difference in height is H1, the top surface point of the lateral wall of the top surface of the lateral wall of the first dense burning-flame port 118 and the second dense burning-flame port 119
