The melted charge is then clarified under fossil fuel burners in a clarifying section, where the highest temperature of the furnace is maintained, and homogenized in a homogenizing section from which the clarified melt is drawn. Flue gas from the clarifying section sweeps the surface of the melting section countercurrently to the charge and is then used to heat combustion air. Burners in the clarifying section are operated under air starved conditions to reduce nitrogen oxides, while burners in the melting section are operated with excess air to achieve complete combustion. | |
