Recycled glass fragment feed to a melting furnace

摘要

For drying and preheating of the material feed to a glass melting furnace, the material is dried in a drying zone (18) through the hot air from a recuperator (11). The material, which is mostly dry, is passed from the drying zone (18) to a following heating zone (21) heated indirectly through the partially cooled exhaust gas from the recuperator.
