Verantis ® provides complete rotary kiln incineration packages including a broad range of waste storage and feed systems (ram feeders, sludge feed systems, liquid injection. Types of waste treated in a rotary kiln incinerator. The rotary kiln incinerator is manufactured with a rotating combustion chamber that keeps waste moving, thereby allowing it to vaporize for easier burning. Rotary kilns used in the cement industry are much larger in diameter and longer in length than the previously discussed 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.
