Conditions occurring in cement rotary kilns assure high destruction and removal efficiency (DRE) of the most stable substances, efficacious dry sorption of acid gases in the alkaline raw meal and heavy metals bounding in the clinker. Adequate operation of hazardous waste incineration in the process connected with cement clinker production does not cause increasing air pollutant emissions. Magnitude of the emissions often does not depend of this if there are using wastes in the cement kiln at all. The work presents a review of DRE levels and stack emissions for selected flue-gas constituents during hazardous waste co-combustion in cement kilns …

A widely employed method of reducing cement production costs is the substitution of traditional fuels with alternative and waste-derived fuels to heat the cement kiln. Cement industry offers the most acceptable method of hazardous waste incineration and co-combustion with significantly lower cost in comparison to incinerators. The high temperatures and long residence times inherent in the operation of cement kilns ensure the almost complete destruction of the organic compounds introduced together with waste fuels. This part of the article presents general characteristic of sort of waste incinerated in cement kilns, way of their charging, advantages and limitations of waste co-combustion …

The article presents measurement results of air pollutant emissions from incineration of selected hazardous wastes in a full-scale rotary kiln equipped with afterburner and a wet installation for flue gas cleaning. This type of kiln is suitable for thermal disposal of many sorts of wastes, both solid and liquid. Four groups of waste were being incinerated during the tests: coke tars, medical (hospital) and pharmaceutical wastes added to greased cleaning materials, a sawdust and used gloves, varnish and lubrication wastes, as well as waste rubber and resins. The study was performed in order to answer the question: is the process …
