Experimental studies show that special melting
devices can be applied to melt 15 to 20 tons of batch per
day per square meter applying intense heat transfer
between the combustion process and batch [8]. The melt
still requires a fining step to remove dissolved gases and
gas bubbles after this batch melting stage. For example,
for a container glass furnace melting 300 tons of glass
per day, the melting-in zone could probably be limited
to a tank surface area of about 15 m2
. Strong mixing,
intense convection will speed up heat transfer and the
dissolution process of the remaining raw materials
(sand, alumina, feldspars, clay, etcetera) in the formed
silicate melt
