Double Chambered Incinerator

The term, ‘incinerate’ means, to burn something until nothing is left but sterile ash.
In an incinerator, the high levels of heat are kept inside the furnace or unit so that the waste is burnt quickly and efficiently.
‘Flue gases’ are generated from this waste burning process.

In a double chamber incinerator, these flue gases are also incinerated in the second chamber before being sent to the air pollution control device
The flue gases are cleaned of pollutants before they are dispersed in the atmosphere.

Ash after incineration is deep buried

Rotary Kiln Incinerator

Rotary kiln incinerators, like the other types, are designed with
• A primary chamber, where the waste is heated and volatilized, and
• A secondary chamber, where combustion of the volatile fraction is completed.
The primary chamber consists of a slightly inclined, rotating kiln in which waste materials migrate from the feed end to the ash discharge end.
The waste throughput rate is controlled by adjusting the rate of kiln rotation and the angle of inclination.
Volatiles and combustion gases pass from the primary chamber to the secondary chamber.
