    Lime Kiln Point - Wa

    The kilns at Lime Kiln Point were used to create lime from limestone. Limestone is a calcium-rich rock made of the shells of microscopic sea creatures. When limestone is heated to a temperature of about 1,600 F (about four times hotter than a standard oven!), the carbon dioxide in the rock burns off, turning the limestone into a toxic material

    Oct 15, 2019 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 takes place at 900 C (1650 F; at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around 1000 C (1800 F; at which temperature
