Patent ID: 7120185

Claim:
A waste vitrification apparatus for vitrifying a feed stream having vitrifiable materials and waste materials comprising: a vessel at least partially formed of an electrically conductive material containing a glass melt and defining a mixing zone; a mixing impeller at least partially formed of an electrically conductive material; a drive shaft extending into said mixing zone of said vessel, said impeller being connected to said drive shaft; means for rotating the drive shaft and said impeller in said mixing zone to disperse the constituents of the feed stream into the glass melt; means for creating electrical current flow between the vessel and said impeller sufficient to heat the feed stream until the vitrifiable material melts to a liquid state forming a solidifiable output including the waste material and the melted vitrifiable material; a settling zone in fluid flow communication with the mixing zone; and an outlet opening through which said solidifiable output is ported for cooling and solidification.
