8 Slide 15 Lime Kiln Heat Rate • Heat rate is a measure of energy efficiency – Units are MM Btu/ton CaO or GJ/tonne CaO – Often stated as MM Btu/ton “product” • Typical range – 5 to 9 MM Btu/ton CaO – 5.8 to 10.5 GJ/tonne CaO – Lower is better Slide 16 Lime Kiln Energy Balance Components • Drying • Calcining : CaCO3 + heat CaO + CO2 • Losses – Heat loss through shell
A lime kiln is used for the calcination of limestone (calcium carbonate) to produce quicklime also called burnt lime. Usually, the heat is around 900 Degree Celsius, but a temperature around 1000 Degree Celsius is used to make the calcination process more quickly. Excessive temperature is discouraged because it produces “dead-burned” lime which is unreactive.
