It is insufficient, waste very big；On the other hand, combustion process is unstable, and tempering alters fire and burns serious, both dangerous, cutting torch also pole partially
Easily burn.
To solve the above problems, there is following technical scheme：
1) by the fuel and gases exit line of traditional gaseous fuel-scarfing oxygen grilled gun, an angle is changed so that
The fuel of flowline and the hyperbaric oxygen of ejection in a certain angle are hit, and the method for breaing up fuel improves atomization, this dependence
One direction air-flow breaks up mode, can not form turbulent convolution, and atomizing effect is poor；There is directionality to burn partially for fuel combustion, easily damage
Bad cutting torch.
2) installed in the oily oxygen hybrid channel after injecting tube component one it is more with wire or powder metallurgically manufacturing
Shape refining device is filtered in hole, reaches by the refining device of heating and further mixes oil and oxygen.
3) the metal atomization device and asbestos atomizer of woven wire have been installed additional in the oil outlet end of petroleum pipeline respectively.
2) purpose of technical solution and 3) is the atomizer filtered using gas mixture by porosity and looseness, is reached
The gentle effect of further miscella, although can have certain dispersing liquid to act on, these filter the device of classes, and material is all
The agglomerating use of filament fiber class, the problem of blocking there are airflow scouring screen warpage and easily, state labile, basic nothing in fact
Method is run steadily in the long term.
