Description
Not extinguished lime is widely used in construction, in production of steel for increase of a rating of sulphidic ore, at cellulose production, for production of paper, for cleaning drinking and sewage. Combustion gases of power plants on coal are also purified by means of not extinguished lime.
Not extinguished lime turns out by means of heating of the shredded and sorted limestone in the rotor or mine furnace. Limestone (CaCO3) breaks up to calcium oxide, i. e. not extinguished lime (CaO) and carbon dioxide (CO2). This reaction called by a kaltsination demands temperature about 1100 degrees on Celsius scale. In the rotor furnace process of heating continues six hours; in the mine furnace the kaltsination takes about 24 - 36 hours.
