INFRARED BATCH LEVEL CONTROL FOR A GLASS FURNACE

摘要

System for maintaining a predetermined thick blanket of batch (11) over a body of molten glass (13) in a glass melting furnace (14). An infrared sensor (18) remotely measures the surface temperature of the blanket of batch (11). The measured surface temperature is compared with a set point temperature for controlling the rate at which batch is fed to the furnace (14).
