ABSTRACT:
In order to conserve fuel in an apparatus for manufacturing glass, a continuous glass-melting tank furnace is provided with a melting compartment, a refining compartment, and a shadow arch between the compartments. The shadow arch is constituted by a cover which extends from a shadow wall at the downstream end of the melting compartment to an end wall at the upstream end of the refining compartment. The melting and refining compartments communicate via a passage beneath the shadow wall at the downstream end of the melting compartment, and a sill is positioned between this shadow wall and the refining compartment. The top of this sill is at least as high as the top of the passage.
