    The limestone must be tested to determine the appropriate technology for calcining Each lime kiln type and design is able to accommodate a given set of limestone characteristics Testing to determine the suitability of a limestone for feed to a lime kiln is performed at minevik Outotec's Process Research & Test Center in Danville, Pennsylvania, USA using proprietary test procedures, referred toThe main chemical reaction in a lime kiln is calcining, the conversion of the calcium carbonate (CaCO3) in the lime mud into calcium oxide (CaO) in the kiln product Energy is required to cause this endothermic reaction to occur, but there are other energy components to the overall energy demand of the kiln as shown in Slide 16 There is the energy required to dry the mud, as well as losses of22 Lime Kiln Principles And OperationsPrecise calcining with energy conservation and emissions control Producing consistently highquality burnt lime for slaking requires not only deep knowledge of the calcining process, but also effective energy conservation and emissions control The lime kiln is a huge consumer of energy in a pulp mill, and a large potential generator of CO 2 emissions Energy and emissions need to beLime kiln ANDRITZ
