Abstract
The melting of glass batch materials by at least one submerged burner generating a flame within the molten batch materials. At least one gas inlet separate from the burner is close enough to the burner to interact with the flame. The separate influx interacts with the flame of the burner to regulate it, thereby reducing the risk of molten materials entering the burner.
Claims25
A method of melting glass batch materials, the method comprising:
- generating a flame with at least one burner outputting an oxidizer and a fuel that react together to generate a flame at the burner that is submerged within the molten batch materials;
- interacting a gas from at least one gas inlet with the flame of the at least one burner, the at least one gas inlet not generating a flame at the gas inlet, and the gas inlet being separate from the at least one burner, but is located close enough to the at least one burner to interact with the flame;
- and
- melting the glass batch materials with the flame of the at least one burner, wherein the flame detaches from the at least one burner, and said interacting comprises regulating a frequency of detachment of the flame with gas fed from the at least one gas inlet.

A method of melting glass batch materials, the method comprising:
- generating a flame with at least one burner, that outputs an oxidizer and a fuel that react together, that is submerged within the molten batch materials;
- interacting a gas from at least one gas inlet with the flame of the at least one burner, the gas inlet is separate from the at least one burner, but is located close enough to the at least one burner to interact with the flame, an axis of the at least one gas inlet is substantially parallel to an axis of the at least one burner, and a nozzle of the at least one gas inlet is less than 50 cm from an outlet orifice of the at least one burner;
- and
- melting the glass batch materials with the flame of the at least one burner, wherein the flame detaches from the at least one burner, and said interacting comprises regulating a frequency of detachment of the flame with gas fed from the at least one gas inlet.
1 more element
A method of melting glass batch materials, the method comprising:
- providing at least one burner outputting an oxidizer and a fuel that react together to generate a flame on a first surface of a furnace, the furnace having several surfaces and holding molten batch materials, and the at least one burner is submerged within the molten batch materials;
- providing at least one gas inlet,which does not generate a flame at the gas inlet, on the first surface of the furnace, and gas inlets and burners are not provided on surfaces of the furnace other than on the first surface of the furnace;
- interacting a gas from the at least one gas inlet with the flame of the at least one burner, the gas inlet is separate from the at least one burner, but is located close enough to the at least one burner to interact with the flame;
- and
- melting the glass batch materials with the flame of the at least one burner, wherein the flame detaches from the at least one burner, and said interacting comprises regulating a frequency of detachment of the flame with gas fed from the at least one gas inlet.
