Vitrification systems

In Figure 2 the flow chart of classic fuel burning incinerator combined with plasma vitrification system of all solid residues is presented. The system is self-supplied in the electric power and it employs only single plasma furnace for vitrification of solids. This way every classic waste incineration plant can be converted to zero waste emission system. The excess of energy in the form of electricity or steam can be sold.

EM C Engineering Associates markets the Vitriflux vitrification system for the treatment of hazardous wastes. The vendor claims that the unique feature of this vitrification system is that fluxing material is added to achieve vitrification at relatively low temperatures. Although this technology has only been tested as an ex situ process, the developer claims that in situ treatment is possible. 

OTD estimated that cement stabilization would produce 2,080,600 yd of stabilized wastes that could not be delisted and would have to be stored as mixed waste. The Duratek vitrification system would generate 417,000 yd of waste that may meet criteria for delisting as hazardous wastes and could be stored as only radioactive wastes (D114432, Appendix A).

Plasma vitrification systems can heat the waste in one of two ways either as a nontransferred arc or as a transferred arc. A nontransferred arc uses two internal electrodes. A small column of injected gas is heated by the electric arc, creating a plasma flow that extends beyond the tip of the torch. Nontransferred arcs heat by conduction and produce a dispersed heat that heats both the waste and the gas around the waste. Nontransferred arc melters can operate as in situ or ex situ processes (D11008N, pp. 3-7, 3-11). 

In Situ Plasma Vitrification In situ plasma-heated nontransferred arc vitrification systems discussed in the RIMS database include the Georgia Institute of Technology Construction Research Center s in situ plasma vitrification system (T0343) and the Teton Technologies, Inc., in situ waste destruction and vitrification system (T0786). A cost estimate is included in the Georgia Institute of Technology in situ plasma vitrification system. 

Westinghouse Savannah River Company Transportable Vitrification System Abstract... 

The transportable vitrification system (TVS) is a large-scale, fully integrated ex sim vitrification system that treats low-level and mixed wastes in the form of sludges, soils, incinerator ash, and many other waste streams. The unit is designed to be transportable and easily decontaminated. Slurried or dry feed is mixed with glass formers, and the glass product is continuously poured into steel containers that are cooled, stored, and eventually disposed in low-level radioactive burial facilities.

The transportable vitrification system (TVS), operated in the USA, uses a Joule-heated ceramic melter (Whitehouse et al. 1995), which has been proposed for installation in other countries as well. However, a cold-crucible melter has also been considered for waste treatment in the USA, Italy, and Korea (Jouan et al. 1998).
