A high-performance sewage sludge incinerator has been developed using a circulating fluidized bed. Demonstration testing verified that (1) water evaporation rate in the bed is about 4 times that for the conventional incinerator, (2) emissions of pollutants at the incinerator outlet were dramatically reduced, (3) the size of the flue gas treatment system is reduced due to the low air ratio, (4) flue gas treatment is simplified by de-SOx with CaCO_3 in the incinerator, and (5) screenings added to sewage sludge are incinerated cleanly and RDF is also used as auxiliary fuel.
