Glass melting furnace refers to the thermal equipment used to melt glass batch in glass manufacturing. The powder distributed according to the glass composition and the added clinker (broken glass) are melted and clarified at high temperature in the kiln to form glass liquid meeting the molding requirements. Glass melting furnace includes glass melting, heat source supply, waste heat recovery and smoke exhaust and gas supply.
The glass furnace technology is developing continuously. The glass technology of Baisheng, a well-known domestic glass furnace engineering company, is summarized as follows:
1, glass furnace flue gas desulfurization and dust removal technology
Heavy oil is generally used as fuel for float glass industry in China. The sulfur content of heavy oil and mirabilite in glass batch lead to a large amount of sulfur dioxide in flue gas and air pollution. Under the circumstance of more and more strict environmental protection requirements, it is urgent to treat the flue gas desulfurization of glass melting furnace. Domestic production lines such as SYP Guangdong Float and Shenzhen CSG Float have adopted flue gas desulfurization technology and equipment, and achieved satisfactory results.
2, glass furnace waste gas waste heat power generation technology and equipment.
The waste gas from the glass melting furnace takes about 30% of the furnace heat, and the usable part of the waste heat accounts for 65 ~ 80% of the smoke exhaust loss. At present, most of this heat is directly discharged into the atmosphere. Realize the power recovery of waste heat resources of glass melting furnace, convert the heat energy in waste gas into clean "electric energy", increase the economic benefits of enterprises, reduce the emission of atmospheric pollutants, realize a win-win situation of economic benefits, environmental protection benefits and social benefits, and open up a road of circular economy belonging to the float glass industry. At present, the waste heat power generation technology suitable for the working characteristics and flue gas characteristics of glass melting furnace has been applied in glass enterprises such as Guangdong Xinyi.
