The main component of limestone as CaC03, the most common impurity MgCO3, SiO2, A1203, Fe2O3. In lime FGD system operating conditions to some MgCO3 soluble lime, while the vast majority of the metal oxide is not dissolved even in strong acid, commonly referred to as inert substances. MgCO3 limestone mainly in two forms: pure MgCO3 and dolomite (CaCO3 · MgCO3). Pure MgC03 soluble in FGD systems lime kiln dust, MgCO3 dissolved SO2 absorption efficiency can be improved, but the high concentration of Mg2 precipitation and dewatering properties affect the byproducts. Dolomite is substantially insoluble in the FGD system, its content increased limestone consumption will increase, reducing the purity of gypsum, while it will also hinder dissolution of the active limestone. As a result, dolomitic limestone (CaCO3 · MgC03) higher vertical lime kiln, the lower its activity. Is a new type of refractory concrete and refractory firebrick compared it with the production process is simple and convenient construction and maintenance, overall good and long life. For lime kiln refractory concrete lining, construction, there are two options, one is the whole cast, and the other is made of small prefabricated masonry blocks, small kiln method can be used before, most of the use of medium-sized kilns The latter method, it is because a small kiln kiln lining small, affected by temperature effects arising from the expansion or contraction of the larger.
