CO2 Reduction from Glass Melting Furnaces by Oxy-Fuel Firing Combined with Batch/Cullet Preheating

According to this conference paper, about 30% fuel savings and 20% reduction in carbon dioxide (CO2) emissions have been demonstrated in an oxy-fuel fired container glass furnace combined with batch/cullet preheating, compared with a state-of-the art regenerative furnace. An advanced oxy-fuel fired glass melting furnace with a new batch/cullet preheater is projected to reduce the specific fuel consumption further to 2.65 GJ/mton and specific CO2 emissions to 237 Kg/ton.
