Introduction of glass furnace

Glass kiln is a melting device that glass manufacturing industry must have. Here are some new technologies that are being improved.

Computer simulation and imitation technology provide a numerical test platform for the development of energy-saving furnaces, reducing pollutant emissions and improving product quality. Using new layout melting furnaces, such as stepped bottom structure, to further improve glass flow, eliminate reflux and reduce "dead zone", realize energy saving and improve glass quality; The structure of fully sealed feeding port can reduce heat dissipation and dust, and improve pre-melting results. By adopting REDOX melting control, bubbles in molten glass can be eliminated to the maximum extent, so that the goal of energy saving and quality improvement can be achieved when the clarification temperature is lowered or the clarification is reduced. Oxygen-enriched incineration technology The preparation of nitrogen gas in float glass factory is an oxygen-enriched atmosphere, which is involved in incineration in the furnace through the process bifurcation pattern, improving thermal efficiency, saving fuel and improving melting quality. Oxy-incineration Technology of Glass Melting Furnace Oxy-incineration technology is a skill with obvious energy-saving and environmental protection effects. At present, only three large-scale float glass melting furnaces in the world have adopted oxy-incineration technology, but its application in domestic float glass production lines is still vacant. There is no need to change the fire in the furnace using the full oxygen incineration technology, and there is no regenerator layout in the furnace with atmosphere combustion.

Oxy-incineration technology can eliminate energy consumption and waste gas emission in the production process and improve the quality of glass. Take a 500t/d float glass furnace as an example, and the results of emission reduction are shown in Table 4. At present, the repulsion of this skill is increasing by leaps and bounds with the inexhaustible low oxygen cost and the increasing energy cost. It is believed that this skill will be popularized and applied in the domestic float glass production line in the near future. Convection melting skills Glass is heated in a melting furnace, mainly by process radiation, and some of it is convection. In convective melting, one or more spray guns are placed on the crown, and the flame reaches the melt skin vertically downward. This convection method may improve heat transfer and energy throttling. This technology has been installed in several furnaces, which can also be used as a kind of refreshing of melting furnace.
