Fluidized-Bed Incinerator
A vertical, cylindrical, refractory-lined steel shell that contains a sand bed and fluidizing air orifices to produce and sustain combustion. Sludge is mixed quickly within the fluidized bed by its turbulent action, resulting in evaporation of the water and combustion of the sludge solids.
The principal thermal reduction methods are described below and illustrated in Figure 6.
