摘要： A glass tank furnace having a high melting rate. The ratio of the length of the glass tank furnace to the width thereof is 2.3 to 2.8. By reducing the area of a furnace and optimizing the length-to-width ratio thereof, the heat loss of the tank furnace is reduced. By designing an appropriate liquid glass tank depth, the temperature of a furnace bottom is improved and the quality of the liquid glass is guaranteed. By providing pure oxygen burners (3) and electrodes (7), sufficient energy is guaranteed, the melting capability and the heating efficiency of the tank furnace are improved, and energy consumption and the discharge amount of carbon dioxide are significantly reduced. Weirs (5) arranged on the furnace bottom improve the outlet temperature of the liquid glass, reduce energy consumption, lower the temperature of the furnace bottom in the electrode area, prolong the service life of the furnace bottom, and guarantee an increased proportion of auxiliary power. By means of the design of bubbles (6) at the furnace bottom, the backflow strength of the liquid glass, the melting capability, and the quality of the liquid glass are improved.
