PLASMA FURNACES FOR TOXIC WASTE PROCESSING
ABSTRAKT
The increasing amount of toxic waste is a serious ecological hazard. Composition of waste is various. In most cases it contains toxic substances, contamination and viruses that need special utilization.
One of the most promising ways of solving this problem is plasma treatment of toxic materials. This process is characterized by a significant reduction of waste. Any complex organic and inorganic compounds can be intensively destructed in thermal plasmas thanks to high temperatures. Melting of ashes allows to obtain thermal, chemical and deactivated forms of glasses or ceramics. For vitrification of wastes (ashes) thermal plasma is generated by an electric-arc plasma torch with bulk temperatures up to 6000 K.
This paper presents plasma furnaces that have been designed for waste treatment: a plasma shaft furnace with a waste processing capacity of 200 kg/h for centralized waste treatment facilities and small chamber furnaces with a 50 kg/h capacity that can be placed in any hospitals, clinics or scientific laboratories. In addition, a plasma combination furnace that is designed for Nuclear Power Station and toxic radioactive waste treatment is also presented. A design procedure based on thermal analysis has been developed to achieve the best performance of furnace operation.
