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.

A fiberglass composite, a glass fiber of same, and a composite material thereof. The fiberglass composite comprises components of the following contents expressed in terms of weight percentage: SiO2 at 58-63%, Al2O3 at 13-17%, CaO at 6-11.8%, MgO at 7-11%, SrO at 3.05-8%, Na2O + K2O + Li2O at 0.1-2%, Fe2O3 at 0.1-1%, CeO2 at 0-1%, and TiO2 at 0-2%, where the weight percentage has a value of C1 = (MgO + SrO)/CaO being greater than 1. The fiberglass composite improves the refractive index of a glass, is capable of blocking rays hazardous to the human body, and further reduces devitrification risks and production costs of the glass, thus allowing the fiberglass composite to be further applicable in large-scale pool kiln production.
