Specific embodiment
The present invention 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, the vertical side plate being sequentially connected by four pieces constitute, generally rectangular shaped structure, are propping up for fuel element 100
Support and protective cover.
Fuel element 100, the blast tube 1 being connected including induction tunnel and with the two-port of induction tunnel and flame mouth；Wherein,
Induction tunnel includes the first separate induction tunnel 21 and the second induction tunnel 22；First induction tunnel 21 and the knot of 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 all 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
First mix the second of air cavity 34 and the second flame mouth 32 and mix 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 that the first of inverted " u "-shaped structure mixes air cavity 34, and first mixes interval on the top surface of air cavity 34
It is provided with multiple first flame holes 39；
Second flame mouth 32 includes vertically spaced interior plate 35 and outer panel 36, between interior plate 35 and outer panel 36
Gap formed second mix air cavity 37, second mix air cavity upper port be 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 interior plate 35 and the first mixed air cavity 34
Between with 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
Plate 36 and interior plate 35 and the first forward and backward two ends for mixing air cavity 34 are separately fixed on the front side board and back side panel of framework 200,
With gap between the left plate of the outer surface of outer panel 36 and corresponding framework, right plate, gap connection air, formed secondary
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 of blast tube is flowed through while the first induction tunnel and the second induction tunnel is sprayed into, with this
Meanwhile, air is also while entered the first induction tunnel and the second induction tunnel by injection, air and combustion gas are carried out in two induction tunnels
After preliminary mixing, respectively enter first and air cavity and the second mixed air cavity is mixed, 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
Flame in the middle upwards position carry out secondary mixing, form secondary complete burned flame.
The burner can effectively reduce the height of flame and the temperature of flame, and so that combustion gas is fully burnt, so as to significantly
Reduce the NOx produced by combustion process, environmental friendliness；Also, as 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.
