Rotary Kiln: Difference between revisions

Line 35:

Rotary kilns are tilted towards the post-combustion chamber. This, along with the slow rotation (between 3-40 rotations per hour), facilitates the transport of solid [[Hazardous Waste|hazardous wastes]] that are fed into the upper end, as well as the bottom ash produced during [[incineration]], in the direction of the post-combustion chamber. These are then removed together with the ash from the post-combustion chamber via a wet bottom ash discharger. The residence time for solid wastes is typically greater than 30 minutes.

A post-combustion chamber is usually used to increase the disintegration of toxic compounds. Additional firing using liquid [[waste]]/support fuel may be carried out to maintain the temperatures required to ensure the complete destruction of compounds in the exhaust gas. The post-combustion chamber provides the necessary time for the incineration of the flue gasses produced in the kiln, as well as for the [[incineration]] of directly injected liquid and gaseous [[Waste|wastes]]. Due to the high temperatures (900-1200°C) and the secondary air introduction in the post-combustion chamber, the [[combustion]] of the exhaust gases is completed, and organic compounds are destroyed. <ref name="ref1" />
