Fluidised bed incinerator

Similar term(s): FBC, fluidised bed combustion


A type of [waste] incinerator made up of a vertical cylinder that contains a bed of sand held in suspension (fluidified) by high-velocity air injected through a grid at the base of the cylinder. The waste products are fed into and burned on the sand bed, which enhances the heat exchange process and supplies sufficient thermal inertia to the system to regulate the combustion process [at a temperature of at least 850°C].

Fluidised bed incinerators use a flue gas cleaning system that is different from rotary kiln incinerators and which avoids any wastewater discharge to surface water.

Waste streams treated in fluidised bed incinerators include fluff and wastewater sludges.
