AP-­-57 Lime Slaker Heating ©ProSonixLLC2010 AP-57 v0814 Application Profile: Lime Slaker Heating A number of industries use hydrated lime addition for their processes. Hydrated lime (or calcium hydroxide, or slaked lime) is usually a dry powder resulting from the controlled slaking of quicklime with water. The exothermic or released heat of reaction is captured and used to evaporate the excess slaking water. High calcium quicklime readily reacts with water to form hydrated lime. The reaction is highly exothermic and the process is known as "slaking". The reaction is usually carried out in a "slaker" (a specially designed mixer) which, through a process of rigorous mixing, makes certain that all of the quicklime has come into i
