<p>A process and apparatus for the vitrification of fly ash produced from an incineration system for solid waste materials, including the combining for fly ash extracted from the pollution control device in the incineration system with fusible material, particularly glass, and preferable recycled glass extracted from the solid waste material before it is incinerated, and susbsequently melting the combined glass and fly ash in a vitrification furnace in order to vitrify the fly ash and its toxic contaminants, including lead, mercury, cadmium and other heavy metals, to produce an inert vitrified ash product. The flue gas from the vitrification furnace is returned to the gas stream from the incinerator for introduction into the pollution control device. <IMAGE></p> |
