METHOD FOR MELTING GLASS IN AN OXY-FUEL GLASS MELTING FURNACE

摘要

The present invention is related to a method for melting glass in a glass melting furnace using oxygen and a pulverized fuel such as petroleum coke. A mixture of pulverized fuel and air is feeding under pressure from at least a feeding means. The mixture of pulverized fuel and air is discharged from the feeding means toward at least one distribution means. The mixture is regulated in a controlled manner from the distribution means to each of a plurality of burners in a glass melting region of the glass melting furnace. A flow of oxygen is supplied simultaneously together with the pulverized fuel-air mixture to each of said burners whereby a combustion cycle is carried out in the glass melting furnace. Finally, the pulverized fuel-air mixture and the flow of oxygen are burned simultaneously by means of said burners in the glass melting region of the glass melting furnace to provide a combustion flame with high thermal efficiency to carry out a controlled heating for melting the glass.
