The project started with cold reactants before operating with hot reactants some months after. Thanks to AGC advanced knowledge on oxy-fuel and AL expertise in oxy-combustion and in full-oxy furnace operations, the furnace has been started-up as scheduled.
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…).
