METHOD AND APPARATUS FOR RECOVERING ENERGY FROM WASTE MATERIALS BY COMBUSTION USING A PORTION OF TERTIARY AIR

摘要

A method and apparatus for using in rotary kilns having a calciner and a tertiary air duct, which uses the hot air from the tertiary air duct for burning wast e material in a combustion chamber formed therein, achieving a complete combustion of the waste material and discharging the hot combustion gas to the tertiary air duct for its use as supplemental energy source by the rotary kiln.
