Reduced Specific Energy Consumption

The glassy nature of Calumite Slag , combined with its chemical composition, leads to faster melting. As a result, the energy required to melt the glass, while maintaining existing furnace temperatures, is actually lower. Depending on the specific furnace design and control parameters, this can be used to reduce the total energy consumption/ton of glass, or specifically to reduce the use of electric boost.

The following graphs illustrate examples where the use of Calumite Slag has reduced the specific energy consumption. In all examples, the data are separated according to the three stages; without Calumite Slag , while Calumite Slag is being introduced, and with Calumite Slag in the batch. The savings quoted are based on the average values before and after the introduction of Calumite Slag .

Introducing Calumite Slag to the amber container glass, figure 3.1, led to a 4.2% reduction in the overall energy consumption/ton of glass, which was maintained with the continued use of Calumite Slag in the batch.

The introduction of Calumite Slag for a trial period in a green container furnace, figure 3.2, showed an average reduction of 3% of the total energy consumption over the trial period. The maximum energy reduction was 5%, which was achieved in conjunction with furnace temperature reductions and glass quality improvements.
