Reduce Furnace Energy Consumption Using Calumite

Depending on the specific furnace design and control parameters, this can be used to reduce the total energy consumption per tonne of glass, or specifically to reduce the use of electric boost. Results are presented of energy savings that have been achieved through Calumite implementation in three different container glass furnaces. Addition of Calumite to a flint container furnace led to an overall energy reduction of 9%, while adding Calumite to an amber container furnace reduced total energy consumption by 4%.

During a Calumite trial in a green container furnace, the electrical energy consumption was reduced by over 25%, due to increases in furnace bottom temperatures that resulted from the faster melting with Calumite. In addition to these energy savings, improved refining with Calumite typically reduces the seed count by at least 50%.
