Cimenterie de Lukala (CILU) is a major cement producer in the Democratic Republic of Congo.
The integrated cement factory, situated in the town of Lukala, experienced several issues as its kiln inlet sealing system did not meet the demands of an efficient and safe kiln operation. The plant saw its lamellar seal quickly destroyed and the regulation of the horizontal thermal expansion of the kiln compromised.
Moreover, false air entered into kiln, which resulted in a temperature drop in the kiln. This led to high energy losses and increased fuel consumption to maintain the clinkering temperature. Variations in temperature prevented the kiln running under optimal conditions.
