Fossil fuel fired vitrification technology is receiving increased emphasis as a potentially attractive means for oxidizing organic materials and immobilizing the heavy metal constituents in hazardous flyashes and dusts. Since vitrification is a high temperature process, there is some volatilization of heavy metals and carry-over of this material, along with a small amount of other inorganic constituents, in the flue gas to air pollution control equipment. In some cases, the carryover can be sold to a metals reclaimer; however, in some instances the presence of other constituents inhibits metals reclamation, and the carryover must be disposed in a hazardous waste landfill.Vortec Corporation proposes to develop an innovative concept for recycling the heavy metal carryover from its hazardous flyash/dust vitrification system back into the oxidizing environmental of the cyclone melter in its advanced vitrification process. Phase I of the proposed program will assess the technical feasibility of the proposed recycling concept via testing with a pilot-scale facility; that is, it will identify the amount of carryover material that can be incorporated into the vitrified product and the heavy metal leaching characteristics of the product.
