ABSTRACT:
A continuous glass-melting tank furnace includes a melting compartment including a melting tank having a lower part, and a superstructure equipped with heaters for receiving and melting raw batch material. Additionally included is a separate refining compartment including a refining tank and a superstructure equipped with a further heater, the refining tank having a lower part and including a transverse sill which divides the refining tank into an upstream refining cell and a downstream refining cell, each of the upstream refining cell and the downstream refining cell having respective upstream ends and downstream ends, and the further heater being arranged to heat melt in the upstream refining cell for creating a spring zone located closer to the downstream end of the upstream refining cell and a circulation of melt in the upstream refining cell which feeds the spring zone. A throat allowing communication between the lower parts of the melting tank and the refining tank, and a conditioning tank for receiving melt from the refining tank are also included.
