Glass Furnace Temperature Sensors

Glass furnaces have significant temperature control issues. Glass furnace temperature can range from around 1100 °C to 1600 °C. Thermocouples need to be made of Precious metals to survive this.

Melter Furnace

During the initial melting of glass cullet, sufficient melt temperature is required to achieve the glass condition required for processing, however excess heating uses extra fuel, shortens plant life and can affect the glass batch properties in an undesirable way.

Melters have temperature sensors in Walls, Roof (Crown) and Bottom. Sensors are often tagged: Melter Bottom, Sump Bottom, Riser sidewall, Channel bottom, Crown, Melter Side wall and so on.… Read more

Tri Level Thermocouple Sensors for Glass Furnaces

Tri Level thermocouples are used in a glass forehearth. They monitor the condition of the glass before forming into shapes. The sensors provide feedback to heaters allowing temperature control across the glass channel. Tri Level sensors have three measuring points at defined positions along the sensor length. Glass depths are often around 150mm. Three measuring points, say 25, 75, and 125mm from the bottom give the temperature profile of the glass flow. A thimble 200mm is normally adequate.

Tri Level thermocouples are often in banks of 4 pieces. One upstream, central in the forehearth channel, detecting the approaching glass flow temperatures, then 3 in a line across the glass channel as the product nears the bowl.… Read more
