Incineration of hazardous wastes using closed cycle combustion ash vitrification

A closed combustion system is used to incinerate hazardous wastes and vitrify ash. An incinerator is provided with pure oxygen, hazardous waste and fuel for incinerating the hazardous waste. Slag from the incinerator is treated separately. Combusted products from the incinerator such as flue gases,...

Beschreibung
Zusammenfassung:	A closed combustion system is used to incinerate hazardous wastes and vitrify ash. An incinerator is provided with pure oxygen, hazardous waste and fuel for incinerating the hazardous waste. Slag from the incinerator is treated separately. Combusted products from the incinerator such as flue gases, liquids, solids and ash are channeled through the system and recirculated back to the incinerator for incineration. A dust collector is used to collect ash from the combusted product and recirculate back to the incinerator. A condensing heat exchanger is used to collect and dispose of waste liquids. Filters are used for filtering particulates from the combusted product. A CaO pebble bed is provided for causing reactions with the flue gases. Remaining insert gas in the system are bled into the atmosphere. Flue gases from the system are recirculated back into the pure oxygen for entry into the incinerator in order to provide temperature control.
