Divided by fuel co-firing kiln, which burn solid fuel, coke, coke and coal. Gas kiln. Including gas-burning kiln firing blast furnace gas, coke oven gas, calcium carbide exhaust gas, furnace gas and natural gas. By kiln-shaped points, vertical kiln, rotary kiln, sleeve kiln, Xi Dewei Masterton kiln, kiln Myers (Switzerland), Fu Kasi kiln (Italy) and the like. While there are positive pressure and negative pressure operation of operating a kiln kiln points. Linzhou modern technology center designed by the 300 cubic meters or less co-firing kilns and 140 cubic meters less gas kiln, in particular blast furnace gas and coke oven gas combustion energy-saving and environmental protection lime kiln XD. Capturing the coke oven gas calorific value, short flame burning problem, it can make full use of the remaining coke oven gas. Coke oven gas from the original "point day light" pollution of the environment becomes a create benefits for enterprises valuable energy. Small and medium steel companies, coking enterprises, calcium carbide enterprises, and refractory industry are very good and effective way to energy-saving, environmental protection and synergistic. 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. 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, furnace kiln, with adhesive containing low melting point calcium compounds, such as wollastonite (CaO · SiO2), Feixian lime kiln, dicalcium (2CaO · SiO3), lime kiln purification, iron and calcium (CaO · Fe2O3 and 2CaO · Fe2O3), etc., as the temperature rise High reaction intensified. These low-melting compounds generated, lime kiln offer, resulting in mutual bond between the lime particles, the particles clog the pores of the surface, not only reduces the activity of the lime, can also block the escape of CO2 decomposition pathways, so that the decomposition of limestone incomplete firing Lime with "core, forming a green burnt lime, resulting lime activity decreased, affecting its quality. When the impurity content is too high, and after the reaction, CaO lime kiln tumor mass formation, resulting in furnace operation disorder. When SiO2, Al2O3 and Fe2O3 or Na2O, K2O, respectively, when the total amount of more than 4 to 5 percent, or 0.1 to 0.2%, easily cause harm to furnace conditions.
