The air or pure oxygen of circle, then volume suction nozzle, reach the effect of both depth premix.Air or pure oxygen can make part or complete
Portion's combustion gas or fuel oil are lighted.
Further technical scheme is air or pure oxygen pipeline spout is flaring structure, and flaring structure provides combustion gas or fuel oil
The medium premixed combustion space of the medium of pipeline and air or pure oxygen pipeline.
Using said structure, combustion gas or fuel oil fully can be premixed after ejection with air or pure oxygen.And the enlarging
Structure can discharge burning vapour lock, and there is provided combustion space.
Further technical scheme is that the expansion angle of flaring structure is 0 ~ 30 °.
Using said structure, 0 ~ 30 ° can make effectively to discharge burning vapour lock there is provided combustion space, and ensure burning
Safety.
Further technical scheme is that the type of attachment of flaring structure is adjustable.
Further technical scheme be combustion gas or fuel passage jet opening distance of the spout from air or pure oxygen pipeline for 20 ~
200mm。
Using said structure, give combustion gas or fuel oil one combustion space, enter First air after protection combustion gas or fuel oil burning
In powder, combustion gas or the de- fire of fuel oil are prevented.
Further technical scheme is that the eddy flow angle of the swirl-flow devices is 0 ~ 90 °, swirl-flow devices and combustion gas or fuel oil
The jet opening distance of pipeline is 10 ~ 100mm.
Using said structure, natural gas is set to produce eddy flow circle, volume inhales the air or pure oxygen of nozzle, reaches that both depth are pre-
Mixed effect.
Further technical scheme is that swirl-flow devices are moveable in combustion gas or fuel passage.
Using said structure, the position of swirl-flow devices can be adjusted, you can to adjust different eddy flow degree as needed.
The present invention has advantages below compared with prior art：Simple in construction, burn controllable, performance safety, it is ensured that combustion
Gas or fuel oil and air or the abundant premix of pure oxygen, make combustion gas or fuel oil be caught fire in advance in air or pure oxygen, it is to avoid de- fire
Phenomenon occurs.

Embodiment
In the embodiment 1 shown in Fig. 1：A kind of combustion gas or fuel oil and air or pure oxygen premixing combustion apparatus, the device by
Include combustion gas or fuel passage 1, air or pure oxygen pipeline 4 from inside to outside, both center lines are same axial line, combustion gas or fuel oil
The spout of pipeline 1 is located in air or pure oxygen pipeline 4, and swirl-flow devices 2, the air are provided with the combustion gas or fuel passage 1
Or the part or all of medium that the medium of pure oxygen pipeline 4 should be met in combustion gas or fuel passage 1 carries out ignition.The present embodiment
The medium transported in middle combustion gas or fuel passage is combustion gas, and the medium that air or pure oxygen pipeline are transported is air.Except this implementation
This collocation mode in example, can also use fuel oil to match somebody with somebody the collocation mode of pure oxygen with pure oxygen, fuel oil with air, combustion gas.Combustion gas
Or the spout of fuel passage 1 is 20mm from the jet opening distance of air or pure oxygen pipeline 4.This distance can also be 30mm, 40mm,
50mm, 70mm, 100mm, 120mm, 140mm, 150mm, 180mm, 200mm, as long as this distance is in the range of 20 ~ 200mm
.The eddy flow angle of swirl-flow devices 2 be 60 °, eddy flow angle can also be 0 °, 15 °, 30 °, 45 °, 75 °, 90 °, as long as eddy flow
Angle is in the range of 0 ~ 90 °.The jet opening distance of swirl-flow devices 2 and combustion gas or fuel passage 1 is 10mm, and this distance is also
