Ultra-high temperature ultra-high temperature shaft kiln shaft kiln for calcining high purity refractory material, and the majority of alkaline material, kiln temperature up to 1900 ℃ -2000 ℃. Now the country has been put into use in ultra-high temperature shaft kiln main performance: effective volume: 3.5m3-19m3; kiln inner diameter: φ700mm-φ1600mm; production capacity: 700t / a-50000t / a; unit of product heat consumption: 2000kJ / kg-2500kJ / kg. Ultra-high temperature shaft kiln utilization coefficient, and high productivity. Actual production, furnace utilization factor of up to 5t / m3-7t / m3d, environmental protection lime kiln, some furnaces up to 7t / m3d-10t / m3d. The main technical measures to achieve ultra-high temperature are: the kiln secondary air to make good contact with the material, to fully absorb the physical heat the material, before entering the calcining zone temperature has reached above 1500 ℃. At the same time the fuel is injected into the kiln through the burner directly on the hot material SAIC of combustion, high combustion efficiency, the furnace temperature coefficient of up to 0.9. 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, small green lime kiln, resulting in mutual bond between the lime particles clogging the particle surface pores, not only reduces the activity of the lime, it can also block the escape of CO2 decomposition pathways, green lime kiln factory, so limestone decomposition incomplete, firing lime with "core, forming a green burnt lime, 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 conditions disorder. When 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 furnace conditions. small green lime kilns, furnaces blue sky, green lime kiln by the Linyi LUOZHUANG Lantian kiln Limited.
