| 20100258263 | OXYGEN HEAT EXCHANGER - The present invention relates to a heat exchanger for the supply of oxygen or of a gas mixture containing at least 50% oxygen, the temperature at the outlet of the exchanger not being below 300° C., it preferably being above 400° C., the oxygen or the oxygen-rich gas feeding one or more burners of a glass melting furnace, the heat of the combustion gases being used directly or indirectly to heat the oxygen or the oxygen-rich gas in the exchanger, in which the exchange power is between 20 and 300 kW, preferably between 40 and 250 kW and particularly preferably between 80 and 170 kW. | 10-14-2010 |
| 20110016923 | GLASS MELTING FURNACE - The present invention relates to a glass melting furnace comprising a channel-shaped melting tank, the batch materials being introduced at an upstream end, the molten glass being recovered at the downstream end, said furnace being heated by means of burners, in which the combustion energy is produced by oxy-fuel combustion in respect of at least 65% thereof, the burners being distributed on the walls along the length of the furnace, in which flue gas discharge is mostly localized close to the upstream end near the openings through which the batch materials are introduced, the rest of the flue gas being removed close to the downstream part so as to maintain dynamic sealing with respect to the surrounding atmosphere. | 01-27-2011 |
| 20110017195 | GLASS MELTING FURNACE - The present invention relates to a glass meting furnace comprising a channel-shaped melting tank, the batch materials being introduced at an upstream end, the molten glass being recovered at the downstream end, said furnace being heated by means of burners, in which the combustion energy is produced by oxy-fuel combustion in respect of at least 65% thereof, the burners being distributed on the walls along the length of the furnace, in which flue gas discharge is mostly localized close to the upstream end near the openings through which the batch materials are introduced, the rest of the flue gas being removed close to the downstream part so as to maintain dynamic sealing with respect to the surrounding atmosphere. | 01-27-2011 |
| 20110072857 | GLASS MELTING FURNACE - 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. | 03-31-2011 |
