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&#xb0; C., it preferably being above 400&#xb0; 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.

Oxygen heat exchanger

The present invention relates to the supplying power to burners for oxy-fuel combustion glass melting furnaces, including a fuel injecting means and a hot oxygen power supplying means, the dispensing of oxygen being carried out so as to develop a staged combustion, a fraction of the oxygen being concurrently injected into the fuel, said oxygen being supplied essentially without heating prior to the supplying thereof into the fuel injecting means.

Power supply for hot oxygen burner

The invention relates to a method for melting vitrifiable materials in a low-capacity oven, wherein at least part of the melting energy is supplied by two oxy-burners projecting into the melting chamber through the upstream wall and arranged on opposite sides of a vertical plane in which a longitudinal axis of the melting chamber is situated, in such a way as to create two flames, the respective injection axes thereof crossing at a distance from the upstream wall, between &#x2153; and &#xbe; of the length L of the melting chamber.
