Abstract
In the manufacture of cement clinker from cement raw meal, sulfide-containing raw materials or raw materials with a high TOC (total organic carbon) level can be used for cement manufacture, which are uncontrollably incompletely burned in the upper cyclone of a heat exchange line, thus leading to high emissions of CO, VOC (volatile organic carbon), and S.sup.2- in the waste gas. To reduce or completely eliminate such elevated emissions, an oxidation zone is provided in an waste gas duct downstream of the heat exchange line in the gas flow path, having an afterburner, the waste gas being caused positively to pass through open flames of the afterburner to assure the economical oxidation of the waste gas.
