Abstract :
Summary form only given. Ashes and sludges (discharged from incineration and waste water treatments of laboratory wastes) were thermally stabilized in a plasma melting system that was conducted at 1,773 K with AC torches under a reduction environment. Flue gas was cleaned up with a venturi quench and packing tower. Volatile mercury in the flue gas was adsorbed by active carbon and recycling via desorption. The flue gas (containing synthesis gas mainly) was introduced to the secondary combustion chamber of the incinerator as auxiliary fuels or a high temperature thermal oxidizer. The TCLP concentrations of slags were less than the Taiwan EPA limits
