Refractory Contribution To Energy Savings In Glass Melting (In French)

Over the past two decades, energy consumption for one ton of glass has been reduced by approximately 25%. Refractories have strongly assisted this reduction. Other factors have also helped, such as the increase in recycled glass content, the changes in specific pull, furnace lifetimes, and the modification of furnace operating parameters with respect to environmental quality. For flame furnaces producing soda-lime glass, this article covers the changes in the recent decades in refractory solutions for every furnace zone, identifying the latest high-performance, innovative solutions which are currently accessible.
