Overheating of the crown in a glass melter promotes accelerated refractory corrosion and wear. Operating a crown at too low a temperature, on the other hand, may reduce melting efficiency and increase fuel consumption. Crown thermocouples provide important data on the operating temperature of the melter, regenerator, and refiner.
