Abstract

PURPOSE: To enhance the efficiency of sludge melting treatment and reduce the running cost by burningly heating sludge beforehand when it is subjected to melting treatment.
CONSTITUTION: Dehydrated sludge (a) previously dehydrated to about 70W80wt% water content is dried to about 1W10wt% water content with drier 1. This dried sludge is fed to burningly heating furnace 2, where it is heated until it is externally burned or carbonized to destroy the fibrous structure. The burningly heated sludge is then pulverized with pulverizer 3, melted in melting furnace 4, and discharged as melt (c). Combustible gas (b) such as CO exhausted from furnace 2 is introduced into furnace 4 and burned.
