Abstract
The present invention relates to a glass melting furnace, comprising a channel-shaped melting tank, the batch material being charged at an upstream end, the molten glass being recovered at the downstream end, said furnace being heated by means of burners, in which 80% of the combustion energy is produced by oxycombustion, oxygen being supplied continuously from a production plant located nearby or via a gas pipe from remotely located plants, characterized in that the furnace is fitted with oxygen storage means such that, should continuous supply cease, the furnace can operate at least in a temperature-maintaining mode for a maximum time of eight hours.
