    摘要： Method of heating the charge of a glass furnace in which at least one burner is placed in a wall of a furnace so as to heat the bath of glass, characterized in that at least one assembly consisting of a first and a second burner which are fed with fuel gas and with oxidizer gas containing at least 50 vol. % of oxygen is arranged in one of the walls of the furnace at a distance (D) at least equal to approximately 3 meters from each other, in that an oxygen lance is arranged between the first and second burners, the first burner, the second burner and the lance forming a combustion assembly and in that from approximately 30 vol. % to approximately 80 vol. % of oxidizer gas is sent into the lance and from approximately 20 vol. % to approximately 70 vol. % of oxidizer gas is sent to the first and second burners in substantially equal proportions, so as to create a retarded combustion of the fuel and oxidizer gases and to extend substantially the length of the flame compared with the length of the flame obtained with no oxidizer gas injected into the lance.

    摘要： In a process for manufacturing glass in a furnace a glass charge in solid form is introduced into a furnace-charging zone at an upstream part of a furnace. The glass charge is moved from the furnace-charging zone to a zone for removing the combustion smoke from the furnace downstream from the furnace-charging zone. The glass charge is moved from the zone for removing combustion smoke to a charge-melting zone downstream from the furnace-charging zone and located substantially in a middle of the furnace and heated by at least one burner. The glass charge is moved from the charge-melting zone to a charge-refining zone downstream from the charge-melting zone. The glass charge is brought to a desired temperature and viscosity in the charge-refining zone. The glass charge is removed from the furnace after the glass charge has been brought to the desired temperature and viscosity. The glass charge, after it has been removed from the furnace, is moved into a feed channel of glass-forming machines. Energy is delivered to the glass charge in the furnace-charging zone in an amount between 5% and 40% of a total energy delivered to the glass charge in the furnace. Energy is delivered to the glass charge throughout the entire furnace such that energy delivery is uniformly distributed over an entire length of the furnace so as to avoid exceeding a crown temperature at a hot spot of the furnace of greater than approximately 1620.degree. C., and so as to maintain a temperature in the furnace-charging zone, measured in a crown of the furnace, at least equal to 1430.degree. C.
