— Shaft kilns are the common type of reactor for the production of quicklime. Limestone (CaCO 3) particles of cm-size are converted to quicklime (CaO) with the energy provided for calcination by the conversion of a typically gaseous fossil fuel.The CO 2 emissions of lime production are severe due to the calcination reaction and the CO 2 …

Practically, the kiln control becomes problematic if the kiln exit oxygen content exceeds 7%. Besides enabling a high output of the kiln system, the precalciner offers greater stability. The calci-nation reaction is strongly endothermic, and it is the control of this reaction that determines the stability of kiln operation.
