ZoloSCAN-GLS : Benefits of Combustion Monitoring for Glass Furnaces


ZoloSCAN-GLS laser paths can be arranged to provide a combustion profile in the furnace.

  • Reduce fuel consumption
    • Balance and optimize excess O2
    • Improve combustion efficiency
    • Balance temperature profile to optimize thermal transfer
  • Reduce emissions
    • Analyze exhaust gas
    • Balance temperature profile to eliminate hot regions
    • Reduce CO, NOx and CO2 emissions
    • Improve regenerator lifetime
  • Improve safety
    • Identify and correct incomplete combustion
  • Improve product quality
    • Monitor and eliminate unburned fuel in melter/refiner

Better Measurement, Better Results

Optimal glass furnace operation requires controlling multiple burners to provide a specified temperature profile in the melting furnace, while minimizing excess O2 to ensure optimal efficiency. Because unspent fuel can cause defects in the glass, high end glass manufacturers also need to ensure that attempts to minimize excess O2 do not result in incomplete combustion. Temperatures inside glass furnaces are exceptionally high, so temperature monitoring is typically limited to thermocouples located in the furnace crown. Flue gas analysis is typically performed with an extractive probe periodically inserted into the regenerator regions. Sensors available for measuring directly in the furnace are very limited. The ZoloSCAN-GLS, however, measures the temperature, O2, H2O and CO in real-time, directly inside the furnace or in the regenerator using TDLAS technology. The ZoloSCAN-GLS delivers quantitative, actionable information that can be used for combustion monitoring and balancing to improve glass furnace performance, quality, and safety.
