Odpady Pestycydowe Jako Paliwo Zastępcze W Piecach Obrotowych Do Wypalania Klinkieru Cementowego, Marian Mazur, Robert Oleniacz, Marek Bogacki, Stanisław Słupek

The clinker burning plant is ideally suited for processing a wide variety of hazardous waste materials. High temperatures existing in cement kilns (ca. 1350-1450 Centigrades in the burning zone) as well as long gas-residence time (ca. 6-10 s) provide potentially excellent conditions for destruction of toxic organic compounds. Non-volatile compounds are retained in the solid phase and built into the clinker. A lot of other (for example acid gases) can also be absorbed by alkaline solid phase. Old pesticide wastes present a big problem in Poland now. They can be use as waste-derived fuels in cement kilns, especially in the …

The paper presents the general conditions associated with running of pesticide waste co-incineration in rotary kilns for cement clinker burning, and describes the behavior of toxic substances entering to this process with waste materials or forming as the result of thermal decomposition. Additional air emissions and their impact on air quality were also assessed.

English title: Prediction of the impact on the state of air pollution for the process of pesticide waste disposal in a cement kiln.

Spalanie Odpadów Niebezpiecznych W Piecach Cementowych. Część 2. Destrukcja Paliwa I Emisja Zanieczyszczeń, Robert Oleniacz

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 …
