Glass melting furnaces with a new kind of roof.
Carbon neutrality is a challenge for the glass-making business. Most of the CO2 emissions in this sector come from melting (70–80% of the total emissions). H.R.A.TM Heat Recovery Area technology is a new way to design a glass melting furnace’s combustio
