Rotary kiln used for burning limestone
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An experimental study of the calcination of limestone has been carried out in a highly instrumented pilotscale rotary kiln Local gas, solids, and wall temperatures and pct Limestone calcination in a rotary kiln Metallurgical and Materials Limestone (calcium carbonate—CaCO 3) is burnt in a kiln, giving off carbon dioxide (CO 2) gas and forming calcium oxide (CaO), which is commonly known as quicklime or lump lime It Lime Kiln an overview ScienceDirect TopicsRotary lime 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 of riding rings Lime mud is 22 Lime Kiln Principles And Operations TAPPI
