Rotary kiln furnaces
Rotary kiln waste incinerators (Figure 17.) are not so popular for the mass
incineration of waste in Europe but are commonly used for the incineration of
hazardous wastes. A rotary kiln rotates the waste in a cylindrical furnace in
order to optimize mixing <strong>and</strong> provide a uniform burn. (Bontoux.,1999)

It usually operates in a gas temperature range of 800°C to 1000°C, possibly with
a post-combustion chamber reaching temperatures of 850°C to 1200°C, <strong>and</strong>
resists well to high temperatures. Gases, liquids, pastes, solids <strong>and</strong> even some
items that are somewhat bulky can be h<strong>and</strong>led in large quantities by rotary
kilns. Even though they are mostly used in a continuous mode, they can also be
operated in batch mode. Small ones can even be mobile <strong>and</strong> allow on-site
treatments. (Bontoux.,1999)
Fluidized bed furnaces
This technology consists in a bed of s<strong>and</strong> kept in a fluid motion by hot air
flowing upwards through it. This air is also used as primary combustion air.
Fluidized beds for waste incineration typically operate in a maximum
temperature range of 750°C to 1000°C, more typically from 750°C to 850°C <strong>and</strong>
they have high combustion efficiency. (Bontoux.,1999)
