Most use environmentally friendly kiln, kiln more polluting earlier been banned, since most of the use of the environmentally friendly kiln, why kiln was purged with it? Lime kiln kiln gas roughly co243%, o2o.2%, co0%, the rest is n2 Shandong Environmental Protection kiln temperature 85-100 ℃. Kiln gas can be removed by washing manner, kiln gas scrubber provided sufficient water from the top of the ring or coke gas flow and countercurrent flow, the dust washed off, and the gas is cooled by 200 ℃ to 20-40 ℃. Packed tower little resistance. Operation (entrance 0-15, 50-70 mm water column outlet) in the case of a little decompression. The tower because of the carbon dioxide gas dissolved in a little water, the temperature should be lowered from 0.2 to 0.4%. Lime kiln in the production process, in order to achieve high yield, high quality, low consumption of the purpose of achieving energy saving. Lime kiln flue gas components O2 content of 14.96% (the content of the text refers to volume fraction), CO2 gas content of 19.91% energy saving kiln, flue gas composition and the ideal: O22% ~ 4% green lime kiln furnace, CO2 about 30%, the gap is relatively large. If the flue gas oxygen content of 4% of the ideal value, calculated according to the existing flue gas oxygen content of 14.96%, the excess air ratio of 1.8145 environmental protection lime kiln, the excess air amounted to 1.8145 times the actual amount of smoke. If the CO2 content of the flue gas by calculating the excess air ratio of 0.5067, then the excess air is about 1/2 of the total amount of smoke. Whether or gas co-firing kiln kiln is a reasonable need for the wind, because any fuel combustion must meet three conditions, namely fuel, air (oxygen), and open flames are not missing any of the conditions for combustion a. The amount is based on the oxygen demand of wind combustible components of fuel to calculate the wind if for lack of fuel would not have sufficient fuel for the excess air excess air becomes smoke away a lot of heat, resulting in increased fuel and waste surface . Its air volume is generally calculated :( formula slightly) its pressure to be calculated depending on the type of kiln, different materials of different particle form resistance. Automatic control is an important feature of the new technology lime kiln, its feeding, ingredients for wind, gas, cinder are done by computer automation. But should also consider the national conditions, plant intelligence, and the value of the cost, the higher the degree of automation is not possible should be the final effect of the principle. Kiln promotion of new technologies, we must first solve the question of perception and understanding. It is required, in the form of social needs, but also the needs of business efficiency. Coal burning green lime kiln, Kim Yong furnace (certification), environmental protection lime kiln by Kim Yong Kiln Ltd. Linyi City. Linyi Kim Yong Kiln Ltd. (www.dfyaolu.com) (www.dfyaolu.cc) is an industry leader in Shandong Linyi, environmental protection equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs. Kim Young-kiln in leadership with the staff warmly welcome all inquiries negotiations to create a better future for Kim Young-kiln.
