The new lime kiln kiln structure beam features of the new lime kiln Beam is a new type of kiln voyage boiler plant introduction and assimilation of the chief architect on the basis of research and development, and even production of lime quality, active high, lime products used in metallurgy , chemicals, building materials with a large amount of ash, lime requirement for high quality industry. The new lime kiln beam system includes the kiln, feeding systems, combustion systems, discharge systems, air supply system and control system. The new lime kiln kiln structure beam characteristics: quasi-rectangular lanes kiln, kiln burner set upper and lower beams and a layer surrounding the burner, Jurong green lime kiln, kiln upper portion of the kiln exhaust collector, kiln gas extraction the upper layer of limestone reserves pipe, the exhaust pipe to the upper layer between the beam to preheat burner layer, using limestone calcination kiln gas after preheating to a temperature calcination, the upper to the lower beam burner burner region between the beam calcined layer and the lower burner beam to lime ash outlet cooling layer, layer of the limestone calcined uniformly calcined into lime, calcined lime-level domain to be adjusted according to quality, production requirements. Effect of chemical composition of impurities in the limestone ore, in addition to the active ingredient-containing CaCO3, but also contains a variety of harmful impurities. There are three main ways to impurity sources: (1) self-contained mineral impurities, such as: SiO2, Al2O3, Fe2O3, K2O, Na2O, P, S and the like. (2) ore in the mining process, ore wall rock or mezzanine mixed impurities. (3) ore in mining, transportation, loading and unloading, ore adhered to the surface of the soil, sand and other impurities. No matter where it comes from impurities, will be on the lime kiln to produce great harm. Calcium-containing compounds such as impurities in the SiO2, Al2O3, Fe2O3, and began firing in lime CaO occurs at a lower temperature (900 ℃) reaction, in the firing zone is easy to form a liquid phase, with a low melting point adhesive, such as silicon limestone (CaO · SiO2), dicalcium silicate (2CaO · SiO3), iron and calcium (CaO · Fe2O3 and 2CaO · Fe2O3), etc., with increasing reaction temperature. These low-melting compounds generated, resulting in mutual bond between the lime particles, coal burning kiln environment, clogging the pores of the particle surface, not only reduces the activity of the lime, can also block the escape of CO2 decomposition pathways, so that incomplete decomposition of limestone, burn lime with a "core, forming a green lime burn, environmental protection lime kiln equipment, resulting in decreased activity of lime, affect its quality. When the impurity content is too high, and after the reaction, CaO lime kiln tumor mass formation, resulting in furnace . operation disorder as SiO2, Al2O3 Fe2O3 and total or Na2O, K2O is at least 4 to 5%, or 0.1 to 0.2%, respectively, is easy to cause harm to the environment kiln burning coal furnace conditions |.
