The lime kiln consists of three principle zones: in the preheating zone, the heat in the combustion products, including carbon dioxide from the dissociation of limestone, is used to preheat the limestone to 1200 K; in the burning zone the limestone is decomposed to quicklime at gas temperatures of 1500 K, a process known as calcining
