REXI grey glass is a product with transitional color from colorless to colored in the process. It is solemn and suitable for serious and authoritative construction and facility like government and procuratorate.
Glass industry is very high-energy-consuming. The melting furnace is the most energy-consuming equipment in the China grey glass factory. The fuel cost accounts for about 35% to 50% of the production cost. The consumption of most of the melting furnaces designed by China grey glass manufacturers can reach 5800kJ/kg, while the foreign companies have 6500kJ/kg to 7500kJ/kg. We have certain advanced ahead of the international average level, which makes grey glass price competitive.
But the thermal efficiency of melting furnaces is generally 25% to 35% and the kiln structure design and insulation measures are irrational. The quality of the refractories used is one of the important reasons. Secondly, the backward operation of domestic technology and the incomplete management are also the reasons that cause high energy consumption, poor melting quality, and short kiln life.
At present, China grey glass suppliers have 140 production lines, and its production capacity has increased rapidly, and market competition has gradually become fierce. As the main fuel, heavy oil prices continue to rise. Therefore, reducing the energy consumption has great significance in reducing production costs, improving the market competitiveness of enterprises, reducing environmental pollution, and alleviating fuel shortages.
