Abstract
A review, with 57 refs., compares various new technols. for increasing the efficiency of glass-melting furnaces. The most important technols. are: batch and cullet preheating, using a fluidized bed for batch preheating and dust filtration; thermochem. recuperators using a reformer; O2 burners; advanced air preheat systems like ceramic recuperators; twin-bed burners; and new combustion technologies. The energy savings of these different measures for an industrial glass furnace was calcd. by an energy-balance model. A soda-lime glass furnace with a prodn. rate of 250 metric tons glass per day was chosen as an example for making these comparisons. Melting of batches with up to 100% cullet may have addnl. advantages for the energy consumption because of the possible lower melting temps. needed to remelt pure cullet without other raw materials. Batch and cullet preheaters are the most important systems for the near future. Besides the improvement of the energy efficiency, the impact of some of the mentioned energy-saving technologies on the redn. of the emission of pollutants like dust, NOx, SOx, chlorides, and fluorides seems to be promising.
