FEEDER FOREHEARTH PRINCIPLE AND OPERATION (INTRODUCTORY TRAINING)
As the fined glass melt exits the furnace through the throat, it enters the conditioning area. Many glass products, such as containers, glassware, and glass wool, are thermally conditioned in the furnace. The forehearth’s purpose is to supply homogeneous glass at the correct temperature to the outlet. Colored glass can also be produced inside forehearths by combining frits directly into the melt. The glass delivery must be well-controlled in stable operation, before and after a job change. This course provides an overview of the various parameters available for optimal feeder control.
Contents
• General principle of feeder and forehearth system
• Thermal heat transfer and temperature homogeneity
• The impact of gas heating and electrical boosting
