<p><P>PROBLEM TO BE SOLVED: To provide a sludge treatment method and a sludge treatment system with a circulating fluidized bed furnace, capable of appropriately maintaining a pressure difference within the furnace without replenishing additional fluid media even when a fluid medium is discharged together with exhaust gas. <P>SOLUTION: In the sludge treatment method, after sludge 3 is dried by a dryer 2, dried sludge 4 is charged to the circulating fluidized bed furnace 10 and is burned while mixed with a fluid medium. In the dryer 2, drying treatment is performed to obtain the dried sludge 4 having 60-30% of a water content, and at least part of the dried sludge 4 charged to the circulating fluidized bed furnace 10 becomes block sludge particles and is circulated within the furnace 10 together with the fluid medium. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
