Electric MeltingCosts & Benefits
|Parent Process: Melting and Refining|
|Energy Savings Potential||
State of the art electric melters consume 2.81 to 2.88 GJ/t of soda-lime or sodium-borate glass (Worrell et al., 2008. p.69)
Thermal efficiency of electric furnaces are 2 to 4 times better than air-fuel-fired furnaces (IPTS/EC, 2013. p. 175)
|CO2 Emission Reduction Potential||
Emission reductions will depend on the nature and efficiency by which electricity is produced and supplied to the site.
Electric furnaces have lower capital costs, but have shorter campaign life (2 to 7 years compared to 10 to 20 years for conventional furnaces) and higher energy costs (In the EU, average electricity costs per unit of energy are 4 to 5 times the cost of fuel oil) (EPTS/EC, 2013. p. 175)
