A method and a system for supplying and burning a pulverized fuel such as petroleum coke in a glass-melting furnace including a glass-melting area and a plurality of burners associated with a pair of juxtaposed and sealed regeneration chambers acting as heat exchangers, wherein the burners are arranged in a series of ports associated with the glass-melting area of the furnace. The system includesmeans for supplying the pulverized fuel through each of the burners in order to melt the raw material and produce glass. The combustion gas emissions generated by the fuel burning process in the furnace are controlled so as to keep the combustion gases clean and reduce emissions or impurities generated by the fuel, e.g. SOx, NOx and particulates. The regeneration chambers are provided with refractories selected from magnesium, alumina-silica-zirconia or magnesia and zirconia-silicate, in order to counter the abrasive and erosive effects of the fuel burning process in the glass-melting chamber. A burner is also provided for supplying the petroleum coke and said burner includes means for simultaneously mixing primary air and a mixture of air and pulverized fuel for burning the pulverized fuel.
