2-2 lime kiln principles and operations

2-2 lime kiln principles and operations

The 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.

Dec 16, 2021 The Wrightsville Lime Kilns were part of a thriving limestone-burning operation established by the Kerr family in 1848. The lime produced by the Wrightsville Lime Kilns was known for its whiteness and purity. Historic maps indicate that the kilns ceased operation by 1909. The kilns were donated to the Borough of Wrightsville in 2000.
