And, the burner intervalve in fuel gas inlet pipe and install a gas diversion block between burner central tube, the burner intervalve in oxygen inlet tube and install an oxygen baffle between burner outer tube.
And described burner intervalve, burner outer tube are all arranged with the axis bias of burner central tube.
Advantage of the present utility model and good effect are:
1, combustion gas of the present utility model and main oxygen enter burner inside through biased tracheae, air-flow produces because of biased and rotates in outflow process, and the ratio of rotary speed and axial velocity is regulated by baffle, thus coordinate change flame profile with burner mouth, flame profile, length and momentum can be regulated as required, effectively expanded the scope of application and the purposes of burner.
2, the utility model devises mobile oxygen momentum adjustable ring and combustion gas momentum adjustable ring, by the inside and outside position of pusher collar, the sectional area of gas channel can be changed, change the burner mouth momentum of oxygen and combustion gas thus respectively, thus change burning velocity and position, flame high-temperature region.
