Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 4, the burner of the gas heater includes：
Framework 200, is made up of, generally rectangular shaped structure four blocks of vertical side plates being sequentially connected, and is propping up for fuel element 100
Support and protective cover.
Fuel element 100, including induction tunnel and the blast tube 1 that is connected with the two-port of induction tunnel and flame mouth；Wherein,
Induction tunnel includes separate the first induction tunnel 21 and the second induction tunnel 22；The knot of the first induction tunnel 21 and the second induction tunnel 22
Structure conventional structure, can be " u "-shaped, or serpentine, and the present embodiment adopts " u "-shaped；First induction tunnel 21 and the second injection
The entrance of pipe 22 connects blast tube 1, and the outlet of the first induction tunnel 21 and the second induction tunnel 22 is respectively communicated with the first flame mouth 31
The first mixed flame mouth 32 of air cavity 34 and second the second mixed air cavity 37.
Flame mouth, including parallel arrangement of first flame mouth 31 and the second flame mouth 32.
Wherein, the first flame mouth 31 includes the first mixed air cavity 34 of inverted " u "-shaped structure, is spaced on the top surface of the first mixed air cavity 34
It is provided with multiple first flame holes 39；
Second flame mouth 32 includes vertical spaced interior plate 35 and outer panel 36, between interior plate 35 and outer panel 36
Gap form the second mixed air cavity 37, the upper port of the second mixed air cavity is the second flame hole 38.
First flame mouth 31 is contained in the inside of the second flame mouth 32, and the upper portion side wall of the mixed air cavity 34 of interior plate 35 and first
Between there is gap, the gap forms the isolated area 33 of first flame of isolation and the second flame.
The upper edge of interior plate 35 mixes the top surface of air cavity 34 higher than first, so that the second flame hole 38 is higher than the first flame hole 39；
Higher than the upper edge of interior plate 35, the upper edge of framework 200 is higher than the upper edge of outer panel 36 to the upper edge of outer panel 36；Outside
The forward and backward two ends of plate 36 and the mixed air cavity 34 of interior plate 35 and first are separately fixed on the front side board and back side panel of framework 200,

Burning air supply passage 300；Referring to the mark in Fig. 8.
In the present embodiment, the flow for flowing through the first flame mouth 31 is 2.8 times of the flow for flowing through the second flame mouth 32, so that first
The first flame that flame hole 39 sprays is the larger main flame of firepower, and the second flame that the second flame hole 38 sprays is the less pair of firepower
Flame.Control primary air ratio is between 1.2～1.5.
During the burner operation, the combustion gas for flowing through blast tube sprays into the first induction tunnel and the second induction tunnel simultaneously, with this
Meanwhile, air by injection also while enter the first induction tunnel and the second induction tunnel, air and combustion gas are carried out in two induction tunnels
After preliminary mixing, the first mixed air cavity and the second mixed air cavity are respectively enterd, respectively via the first flame hole and the second flame after mixing again
Hole sprays, and carries out first time imperfect combustion；At the same time, auxiliary air is entered via air supply passage, with first time burning
In the middle upwards position carries out secondary mixing to flame, forms secondary complete burned flame.
The burner can effectively reduce the height of flame and the temperature of flame, and make combustion gas fully burn, so as to significantly
Reduce NOx produced in combustion process, environmental friendliness；Also, because the first flame hole is less than the second flame hole, the second flame is from the
One flame both sides also act as the effect of steady flame to the first flame, effectively prevent tempering and from flame, improve safety in utilization.
