Abstract: A method for heating a liquid glass channel of a glass fiber tank furnace. The method comprises: passing oxygen gas and a fuel, via a burner (1), into a channel space (3) for combustion to heat the channel space (3) and a liquid glass (2), wherein the flow rate of the fuel is VF and the flow rate of the oxygen gas is VOX such that the relative velocity difference D=(VF?VOX)VF. The temperature of the channel is 0-1500° C., and the relative velocity difference D is kept to 25% or more. A pure oxygen combustion method is used for heating a tank furnace channel to reduce waste gas emission and heat loss, thereby achieving the goals of energy conservation, reduced carbon emissions, and improve environment friendliness. The fuel flow rate, relative velocity difference, and related parameters can be controlled according to the temperature of the channel, providing excellent uniformity and accurate control of the temperature of the channel.

Abstract: 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.
