    摘要: Raw materials are fed into the charging end of a melting section which is heated by electrodes in the glass bath. 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.

    摘要: Disclosed are an energy saving method for melting glass in and a glass melting furnace for the practice of the method.A charge is melted in a melting section, clarified in a clarifying section adjoining the melting section, and then homogenized in an adjoining homogenizing section of increased bath depth and drawn therefrom. The charge is fed in at the beginning of the melting section and energy is supplied underneath the charging end through electrodes. The melting energy input is generated by combustion by fossil fuel burners in the clarifying section. The burner flue gases flow over the melting section countercurrently to the charge and are exhausted close to the charge end. The surface of the melting section is swept by a flow coming from the clarifying section countercurrently to the charge.The invention is also in a glass melting furnace for the practice of this method, in which, for the formation of the hot surface flow as a counterflow to the charge movement, the melting section bottom slopes downwardly from the clarifying section to the charging end. The roof of the furnace between the burner section and the charging section has at least one radiation barrier extending to just above the bath surface.

    摘要: The temperature or temperature profile of an electrically conductive molten mass heated by electrodes immersed therein is measured during continuous operation by momentarily cutting off the electrical energy supplied to the heating electrodes, passing measuring currents through the molten mass via the heating electrodes during the momentary cut off, measuring the electrical resistance between pairs of heating electrodes in measuring paths defined by such electrodes and then calculating the temperature existing within the individual measuring paths on the basis of the measure resistance values.
