Development of Circulating Fluidized Bed Incinerator for Sewage Sludge

Abstract

A high-performance sewage sludge incinerator has been developed using a circulating fluidized bed. Demonstration testing clarified that (1) dried sludge and sediment added to sewage sludge are incinerated cleanly, and that (2) increases in primary air and fluidized materials result in an increase in desulphurization efficiency due to enhancing the movement of desulphurization material, especially, in lower part of the furnace.
