A process and apparatus for the vitrification of fly ash produced from an incineration system for solid waste materials, including the combining of fly ash extracted from the pollution control device in the incineration system with fusible material, particularly glass, and preferably recycled glass extracted from the solid waste material before it is incinerated, and subsequently 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 flue gas stream from the incinerator for introduction into the pollution control device.
A process for treating solid waste materials comprising the steps of:
In a process for treating solid waste materials including a primary furnace for mass burning the solid waste material, a flue gas conduit for removing flue gases including fly ash from the primary furnace and a pollution control device in communication with the flue gas conduit for removing fly ash from the flue gas, a method of treating the fly ash comprising:
In an apparatus for incinerating and treating solid waste material including an incinerator furnace having an ash discharge outlet and an incinerator flue gas outlet, a pollution control device having an inlet, a flue gas outlet and a fly ash outlet, and a flue gas conduit in fluid communication between said incinerator flue gas outlet and said inlet to said pollution control device, a device for treating said fly ash comprising:
