Description
Technical field
Technical field of burner is the utility model is related to, it particularly relates to a kind of low NO.
Background technology
Industrial burner is that fuel is mixed and sprayed in a certain way with combustion-supporting gas by one kind, makes fuel combustion heat release
Device, the heating available for devices such as industrial furnace and boilers.
At present, the processing mode of oxynitrides is directly to discharge caused by the burning of traditional combustor, not to it
Second-time burning processing is carried out, while directly discharge can pollute to environment, and because its burning is insufficient, directly discharge can be led
Cause the wasting of resources, increase burning cost.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of low NO, can overcome existing
There is the above-mentioned deficiency of technology.
To realize above-mentioned technical purpose, what the technical solution of the utility model was realized in：
A kind of low NO, including combustor body, drive device is connected with above the combustor body, it is described
The lower section of combustor body is provided with combustion-supporting chamber, and the right side of the combustion-supporting chamber is provided with air intake, and is set at the air intake
There are several air control valves, the right side of the combustor body is provided with fuel inlet, is connected with the right side of the fuel inlet
Boiler, the boiler is interior to be provided with flame jet, and the flame jet is connected with fuel inlet, is provided with described flame jet
Porous type is connected to economizer and return valve, the return valve from the return air inlet that flows back on the right side of the boiler
It is connected with combustion-supporting chamber.
Further, described boiler is connected by secondary back pipeline with return valve.
Further, described boiler is connected by pipeline one with economizer.
Further, described drive device is motor.
Further, the quantity of the air control valve is 2.
The beneficial effects of the utility model：By porous type from flow back return air inlet can oxynitrides gas obtain
Burn again, reduce the discharge of oxynitrides, reduce the pollution to environment；Can be to caused by secondary back pipeline loop
Oxynitrides gas carries out second-time burning, and then reduces the waste of the energy, finally realizes cost-effective effect；This practicality is new
Type is simple in construction, easy to operate.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the scope of the utility model protection.
As shown in figure 1, a kind of low NO according to the utility model embodiment, including combustor body 2, institute
The top for stating combustor body 2 is connected with drive device 1, and the lower section of the combustor body 2 is provided with combustion-supporting chamber 13, described combustion-supporting
The right side of room 13 is provided with air intake 10, and several air control valves 11, the burning are provided with the air intake 10
The right side of machine body 2 is provided with fuel inlet 3, and the right side of the fuel inlet 3 is connected with boiler 6, flame is provided with the boiler 6
Spout 5, and the flame jet 5 is connected with fuel inlet 3, and porous type is provided with described flame jet 5 from the return air inlet that flows back
4, the right side of the boiler 6 is connected to economizer 8 and return valve 12, and the return valve 12 connects with combustion-supporting chamber 13
Connect.
In one embodiment, described boiler 6 is connected by secondary back pipeline 9 with return valve 12.
In one embodiment, described boiler 6 is connected by pipeline 1 with economizer 8.
In one embodiment, described drive device 1 is motor.
In one embodiment, the quantity of the air control valve 11 is 2.
In order to facilitate above-mentioned technical proposal of the present utility model is understood, below by way of new to this practicality in specifically used mode
The above-mentioned technical proposal of type is described in detail.
When specifically used, the utility model first opens air control valve so that air enters from air intake to be helped
Room is fired, is then turned on drive device, fuel is put into from fuel inlet, fuel is mixed with air and is sprayed from flame jet,
Now released because oxynitrides gas caused by burning can be burnt away by porous type from the return air inlet that flows back into flame jet
Thermal discharge, the oxynitrides gas after burning can be sufficiently mixed by secondary back pipeline into combustion-supporting chamber with air, afterwards
Again by flame jet combustion heat release amount again, a circulation is at this moment just completed, completion of this circulation can cause nitrogen
Oxygen compound can fully burn, and so as to reduce pollution of the exhaust emissions to environment, while and can enough reduces the waste of the energy, most
Reach cost-effective effect eventually.
The utility model can adjust the speed that air enters by two air control valves, and then allow fuel to fill
Divided combustion, also enable the oxynitrides gas to come by secondary back pipeline to be sufficiently mixed with air, make its burning
More fully, reach save the energy effect；The present apparatus has the characteristics of easy to operate, simple in construction simultaneously.
The utility model may be such that oxynitrides gas fills by porous type from backflow return air inlet and secondary back pipeline
Divided combustion, the final discharge for reducing oxynitrides, reduce pollution of the exhaust emissions to environment.
In summary, by porous type from flow back return air inlet can oxynitrides gas burnt again, drop
The discharge of low nitrogen oxide, reduce the pollution to environment；Can be to caused oxynitrides by secondary back pipeline loop
Gas carries out second-time burning, and then reduces the waste of the energy, finally realizes cost-effective effect；The letter of the utility model structure
It is single, it is easy to operate.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
