Energy-saving Method

The glass industry is an energy-intensive industry, energy consumption of glass furnace glass production line equipment, fuel costs in the glass cost about 35%~50%. Designed most of the float glass furnace in China consumption can reach 6500kJ/kg~7500kJ/kg glass glass, float glass of the foreign enterprise 5800kJ/kg glass, we have a gap with international advanced level [1].

Thermal efficiency of the glass furnace in 30%~40% in developed countries, the average thermal efficiency of the glass melting furnace 25%~35%. Structure design of furnace insulation measures and unreasonable, use low quality grades of refractories is one of the important reasons for this gap. Secondly, domestic float glass process technology, management is not perfect also contributed to high energy consumption, furnace, melting quality difference short life reason. Until now China has a float glass production line more than 140 articles, glass capacity increased rapidly, market competition gradually heated. Glass main fuel heavy fuel oil prices continue to rise, costs account for a growing proportion of glass. Therefore, reduce energy consumption and to reduce production costs, improve the market competitiveness of enterprises, reduce environmental pollution, ease the energy shortage is of great significance.

Glass of energy conservation is a long-term task, active research technical personnel at home and abroad, such as optimization of structure design of furnace, oxygen-enriched combustion, oxy-fuel combustion electric boosting, heavy oil emulsifying technology. At present, many companies have started to implement energy-saving measures in the production process, and glass production process control and other aspects of energy-saving measures to be explored.
