Abstract

A glass melting oven for producing a glass melt in a row arrangement, having a loading opening for raw glass materials, a melting region, a refining region, a constriction, a conditioning region and an overflow into a processing unit. To remove flaws from the melt that remain visible in the end product, a method includes the steps of a) arranging a refining bench between the melting region and the beginning of the refining region; b) arranging side burners and extraction openings for flue gases between the loading opening and the refining bench; c) delimiting the constriction at both ends by end walls that leave narrow flow cross-sections above the glass melt for flue gases; and d) cooling the glass melt inside the constriction. The glass melting oven is particularly suited for producing flat glass and panels for solar elements. The oxidants for the fuels may also be preheated.
