Saving Energy In Electric Melting And Boosting

Direct electric melting of glass has a fundamental energy efficiency advantage over any form of indirect heating, whether it is fuel or oxy-fuel firing or indirect heating by radiat electric elements. Immersed electrodes and direct joule-effect heating release the melting energy directly into the body of the glass, with losses of typically less than 3% between the primary power input to the furnace or boosting system transformers and the net energy released into the glass.
