<p>Disclosed is a glass melting furnace which is capable of suppressing an increase in the amount of emission of CO2 and NOX and adequately regulating the water content dissolved in molten glass. The glass melting furnace comprises a plurality of burners (31-50) on side walls (13, 14) of a flow path (23) from a front wall (11) to a rear wall (12) of a melting chamber (10), wherein 30% to 90% of the total combustion heat Qa per hour of the plurality of burners (31-50) is generated by oxygen combustion burners. Each side wall (13, 14) of the melting chamber (10) has one exhaust port (24, 25) positioned so that the exhaust ports face one another, and at least one each of an oxygen combustion burner and an air combustion burner is provided in a region at least 0.6 L away in a backward direction from the exhaust ports (24, 25). Of the total combustion heat per hour of the burners provided in the region, 5% to 95% is generated by the air combustion burner.</p> |
