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.
Claims16
A method of processing a mixture of bottom ash and fly ash by melting, said method comprising the steps of:
- taking out bottom ash which has undergone a moistening process from an incinerator;
- subjecting said bottom ash to a drying process until the water content of said bottom ash becomes less than 10 weight %;
- taking out fly ash from a discharge gas processing system of said incinerator separately from said bottom ash without a moistening process;
- weighing portions of said bottom ash and said fly ash separately;
- discharging said weighed portions onto a same transporting device;
- and
- transporting said discharged portions of said bottom ash and fly ash by said transporting device into a melting furnace while mixing said discharged portions together.
