Rotary kiln incinerator


A type of [waste] incinerator mainly used for the thermal treatment of hazardous waste.

A rotary kiln is made up of a slightly inclined cylinder that rotates to facilitate the constant advancement of the waste being fed in. The waste is fed into the upper extreme of the kiln, and the combustion residue is deposited from the opposite (lower) end. The plant has extensive [flue] gas washing equipment and an energy recovery system.

Rotary kiln incinerators use a flue gas cleaning system that is different from fluidized bed incinerators and that lead to a wastewater discharge to surface water.

The waste streams treated in rotary kiln incinerators are solvents and waste oils, wastewater filter cake, and paint and ink residues.
