Tundish preheater with oxygen burner

Tundish preheater with oxygen burner

Diffusion combustion oxygen flame!　Variable flame shape!　Variable oxygen concentration!

Product Overview This preheating system uses an oxygen burner to preheat the tundish in continuous casting equipment in the steelmaking process, achieving higher energy savings compared to preheating with a conventional air burner.
The use of oxygen burners offers the following advantages
  • Short time preheating is possible
  • Low gas usage
  • Preheating to high temperatures minimizes heat shock to tundish refractories when receiving steel
    →Longer refractory service life and repair cycles
  • Preheating to high temperatures allows for lower steel output temperatures from electric arc furnaces and converter furnaces.
    →Leads to a reduction in electricity consumption rate
In addition, the ability to save energy has the effect of reducing CO₂ emissions, making it an excellent facility from an environmental standpoint.
This system consists of our original diffusion combustion oxygen burner, optimum combustion control system, drive unit, control piping equipment, and control panel.
forte
  1. Diffusion combustion oxygen flame: local heating (local heat), prevents refractory meltdown.
  2. Variable flame shape: Flame (long flame, short flame, or flat flame) to suit the shape of the heating space.
  3. Variable oxygen concentration: Optimal combustion conditions can be proposed according to the user's utility costs.
Advantages
  1. The oxygen concentration in the combustion area is changed by controlling the amount of air and oxygen injected into the burner.
  2. Optimal operation is possible according to the user's available oxygen supply.
