Abstract: Bottom ash is taken out of an incinerator after undergoing a moistening process and is subjected to a drying process to reduce its water content to less than 10 weight % or it is taken out of the incinerator with water content less than 10 weight %. Fly ash is taken out of the discharge gas processing system of the incinerator without going through a moistening process. The bottom ash and fly ash, thus taken out, are separately weighed and discharged to a same transporting device and are transported to a melting furnace while being mixed together.
Abstract: An incinerator for drying then cleanly burning trash. The incinerator includes an upper rotating trash drying tumbler for receiving and drying trash and a lower rotating trash burning tumbler interconnected to the upper tumbler for receiving dried trash therefrom. The lower rotating tumbler includes a meshed screen thereabout for complete combustion of the trash therein. The heat produced from the burning trash in the lower tumbler causes the drying of trash in the upper tumbler. A rotating fire tray is situated below the lower tumbler for collecting and reburning any material falling from the lower tumbler and for retaining combustible material for igniting the dried trash in the lower tumbler. When the interior temperature of the incinerator is high enough, the trash in the lower tumbler is self-ignited and heat produced from burning material in the fire tray is no longer necessary. Air exhausted from the drying and burning of the trash is filtered before being exhausted into the atmosphere.
