Ceramic Frits and glazes


In ceramic frit melting furnaces, combustion occurs using natural gas and an oxidizer that can be air or O2.

In ovens with gas/air burners, good regulation of the burner air and its balance with the internal pressure of the oven can reduce the excess %O2 in ranges from 1% to 2%, which implies standard savings of 3% to 5% of fuel, in addition to reducing the amount of CO2 and NOX emissions produced.

In those furnaces with gas/O2 burners, controlling the oxidation level of the kiln atmosphere allows for a finer adjustment in O2 and fuel consumption. Furthermore, in plants with their own O2 production, variations in its purity (90% – 95%) are common, making continuous control of the combustion atmosphere even more crucial.

In general, a ceramic frit furnace without continuous control of excess O2 in the chamber generates:

  • Greater fuel and oxidizer consumption (O2).
  • Structural damage to kiln’s refractory.
  • Possible problems in the quality of the final product (bubbling, tones, etc.).
  • Greater pollution (CO2, CO, unburned, etc.).
  • Variation in the atmosphere due to changes in the purity of O2
