cuopla is made from a 50 gallon water heater
tank. it is 18" od 10" id and can melt up to 45# of grey iron
every 5 to 10 minutes. constructed with nearly 350# of refractory
lining and another 150# of steel . draft is induced by high
pressure air in the two nozles on the top of each hot air return pipe
or into the caped ends at the "t" or by blowing low pressure air into
the bottom of the heat exchanger at the back. the caps are
clear or inspect the tuyere. the hot air
is drawn through the upper section by the two draft inducers then
entering the tuyeres through the two "t"'s.
the tap hole is seen in the front, slag hole in the back.
the drop bottom allows the clearing of a charge.
a sand bottom must be built on the door and refractory lining on the tap hole and slag spouts.
