With the realities of global warming and plans for CO2 reduction, this paper by glass manufacturer La Maison Française du Verre and support by Glass Service a.s, will discuss the operation of a hybrid melter with a high degree of electric boosting, resulting in significantly reduced CO2 emissions. The combustion space above the glass melt is oxygen/natural gas fired along with electric boosting.This furnace illustrates what could be a design for the future of melting. The combination of the top firing and electric melting has been successful in optimising the energy efficiency and reducing the carbonised emissions. After a short presentation of the different steps validated for the decarbonation of the furnace, an overview of the studies to achieve the last rebuilt of the furnace will be described. Finally, energy efficiency will be compared to a standard furnace of a similar footprint.
