GLASS MELTING
Before glass can even be formed, raw materials, mainly sand, and recycled glass must be melted at extremely high temperatures (1,400°C). To achieve the heat intensity required in the glass furnaces, Air Liquide steps in with oxy-combustion technologies that replace air with oxygen, thus improving the melting process, reducing air pollutant emissions and saving fuel. Our solutions allow for rapid alternation of melting temperatures, for operational flexibility and for automatic temperature control in a wide range of glass furnace sizes.
GLASS FORMING
Air Liquide supplies protective atmospheres and oxy-combustion solutions to drive molten glass from the melting furnace to the forming units.
GLASS CONDITIONING
Before a finished product can be packaged and put on the market, defaults must be removed. Air Liquide supplies oxy-natural based gas and oxy-hydrogen based combustion technologies to polish the product surface and remove the defaults present in glass.
Air is commonly used to provide oxygen for combustion to heat industrial furnaces. Heat Oxy-Combustion is an innovative technology that consists of preheating oxygen and natural gas at high temperature generated by combustion fumes. Compared to oxy-combustion without preheating, it reduces fuel and oxygen consumption to the extent that oxy-combustion is economically beneficial to all types of glass.
