Industrial results - Cold reactants

The following parameters have been tracked with special attention:

• Flame length: During the cold reactants phase, no difficulty was encountered about flame length. ALGLASS SUN burners provided the power distribution expected by the process: long flame at high power for reaching the middle of the glass surface, short flame when necessary to adjust batch length.

• Flame emissivity: The aspect of oxy-gas flame without preheating is luminous, the luminosity depending on burner power.

• Crown temperatures: The crown temperatures are similar to air-firing conditions. This can be achieved specially thanks to ALGLASS SUN technology that allows reaching low temperature flames contrary to pipe-in-pipe burners, avoiding thus local overheating.

• Flue gases: The main results can be summarized as followed:
  • Oxygen concentration is similar to traditional full-oxy furnaces (container, fiber, solar…).
  • No excessive carryover.
  • No CO.
  • Standard fumes temperature for oxy-fuel furnace.
