摘要

A glass-melting furnace is provided with means for sensing the batch in the furnace. More specifically, the sensor determines the level or height of the batch in the furnace without physical contact therewith and with the aid of this value, the thickness of the batch can be determined. With the batch thickness known, the power input for the electrodes of the furnace can be changed or the supply of batch to the furnace can be altered to maintain the batch thickness at a constant value in the furnace or to maintain the glass level constant.
