ABSTRACT:
Disclosed is an improved efficiency glass melting furnace and a method of operation in which a mixture, or batch, is fed at a narrow side of a rectangular glass melting tank onto the molten glass mass (or bath) across the full width thereof. The furnace includes burners positioned adjacent to the opposite narrow side for supplying energy, and heat exchangers for energy exchange between the combustion exhaust gases and the combustion air supplied to the burners. The exhaust gas openings are disposed adjacent to the mixture feeding area. The furnace is provided with at least one thermal radiation shield between the burner and feed sections which extends to a small distance above the molten glass.
