Lime kiln Wikipedia
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide) The chemical equation for this reaction is CaCO3 + heat → CaO + CO2 This reaction can take place at anywhere above 840 °C (1,540 °F), but is generally considered to occur at 900 °C 展开From the fuel requirement point of view, rotary kilns are the most flexible of all lime kilns (Oates, 1998) They are successfully fired with natural gas, fuel oil, and pulverized fuels of all types Lime Kiln an overview ScienceDirect TopicsWHAT IS A LIME KILN? Rotary kilns are large steel tubes that are lined on the inside with refractory bricks They are slightly inclined from the horizontal and are slowly rotated on a set LIME KILNS, HEAT TRANSFER, CONTROL AND COMBUSTION Metso has supplied more than 210 lime calcining systems, over 115 of them as preheater/rotary kiln systems The worldwide total annual production capacity from Metso supplied systems exceeds 30 million metric tons per yearLime Metso
