All electric furnaces (AEF) are used for many types of glass, especially for glass types that tend to evaporate, e.g. borosilicate glasses and opal glasses.
JSJ´s state-of-the-art all electric furnaces range from 5 t/d – 200 t/d.
The all-electric furnace (AEF) is heated only with electric current and operated with a cold top furnace. This eliminates hot exhaust gases that could be contaminated with evaporation products of the molten glass.
There are increasing applications for soda lime glasses when unacceptable emissions at the site or the use of renewable energies are driving the decision.
The geometric shape of the basin can be square, dodecagonal or rectangular.
The electrodes are installed as top, bottom or sidewall electrodes which deliver the melting energy into the melt. The glass bath is completely covered by a mix of batch and cullet. This allows operation with a cold top furnace and reduces energy losses of the melt.
