The glass melting furnace (12) comprises burners (13), a ceramic membrane of perovskite type for separating oxygen (14) from a gas mixture, a boiler for additional heating of the gas mixture, a first heat exchanger (26), and a second heat exchanger for reheating gas mixture of which the oxygen is extracted. Combustion energy is partially produced by oxy-combustion during heating. The gas mixture is first compressed and then heated, and the separation of oxygen from the gas mixture is carried out at 950[deg] C under a pressure of 1x 10 6>Pa to 5x 10 6>Pa.

The gas mixture is first compressed and then heated, and the separation of oxygen from the gas mixture is carried out at 950[deg] C under a pressure of 1x 10 6>Pa to 5x 10 6>Pa. The fumes are passed through the first exchanger by raising the temperature of a coolant fluid, and has a temperature of greater than 800[deg] C. The oxygen-depleted gas mixture after passing through the separation membrane is used for functioning a compressor turbine for compressing the gaseous mixture. The hot oxygen separated from the mixture is directly conducted to the oxy-fuel burners. The gas mixture further comprises atmospheric air. |
