QUESTION:we are manufactures of glass marbles in india . we will to get a
knowhow of making a furnace for producing glass marbles non stop using
petroleum coke or furnace oil. cost of fuel should be very low and no
biiger than 7 tonnes furnace we would like to make.
ANSWER: We are manufacturers of glass marbles in India. We would like to get know
how in order to make a furnace for producing glass marbles non-stop
(continuous melt) using petroleum coke or furnace oil. Cost of fuel should
be very low and the furnace need be no bigger than 7 tonnes (of 1000
kilograms or 2200 pounds)
Reply
There are glassblowing factories in India shown videos that circulate in
this country where coal and coke are used for fuel and people blow glass
barefoot. The evidence available in this century in the U.S. or Australia
or Europe is not going to be very helpful for use with dirty fuels.
When England banned wood burning for glassmaking and coal was adopted
there, it was found necessary to use closed pots to keep from contaminating
the glass. Hooded pots are available in Europe which stand inside a furnace
chamber that is heated around the pots, the opening of the pot facing an
opening in the side.
Unfortunately, continuous melt of glass where batch or cullet or both are
piled on top of glass at the back of a tank and the molten glass passes
under a barrier that keeps the unmelted materials out of the clean melt is
going to be very tricky with indirect heating.
