Abstract:
A lightweight compact furnace for the treatment of wastes which comprises:(a) a primary solid treatment chamber containing a crucible in which the wastes are transformed into molten slag and volatile compounds;(b) a secondary combustion chamber for treating said volatile compounds generated in the primary solid treatment chamber to insure complete combustion of said volatile compounds;(c) a slag processing and storing chamber for cooling and transporting the slag formed in the crucible of the primary solid treatment chamber and for removal of the slag from the furnace; and(d) wherein the walls of said primary solid treatment chamber and of said secondary combustion chamber comprise an inner wall structure made of a metal retaining desired mechanical properties at the furnace operating temperatures, one side of said inner wall structure facing a hot chamber interior and the other side of said inner wall structure having a gap, means for blowing cooling air through the gap, and means adapted for controlling the cooling air passing through said gap so as to maintain said inner wall structure at a predetermined temperature during operation of the furnace, said walls also having an outer steel shell following said gap.
