METHOD FOR MELTING GLASS

摘要

The present invention is related to a method for melting glass using the combustion of pulverized fuel as a heating source for melting raw materials for producing glass. The method comprising the steps of, feeding a regulated controlled flow of a mixture of pulverized fuel and air or gas under pressure for pneumatic transport in at least one distribution means; discharging the mixture of pulverized fuel and air or gas from feeding means toward at least one of said distribution means; regulating in a controlled manner the pulverized fuel-air or gas mixture from the distribution means to each of a plurality of burners in a glass melting region of the glass melting furnace; supplying simultaneously a second fuel together with the pulverized fuel-air or gas mixture to each of said burners whereby a combustion cycle is carried out in the glass melting furnace; burning simultaneously said pulverized fuel-air or gas mixture and said second fuel by means of said burners in the glass melting region of said glass melting furnace while providing a combustion flame with high thermal efficiency to carry out a controlled heating for melting the glass; and, counteracting erosive and abrasive effects of the pulverized fuel in the glass melting furnace by means of refractory materials.
