Limestone calcination process can be divided into the following four steps: (1) thermal expansion limestone begins to break down in front of from room temperature to about 900 ℃, and environmental protection lime kiln vertical, its volume will vary due to thermal expansion. (2) decomposition of calcium carbonate limestone surface when the temperature reaches or exceeds the calcium carbonate decomposition temperature of 898 ℃, the calcium carbonate in limestone began to break down, a new environmentally friendly kiln, decomposition time required depends on the size and limestone calcination zone temperature. During the decomposition of limestone surface moving from the surface to the inside, green lime kiln factory to produce lime attached to the not yet decomposed limestone, CO2 generated escape from the limestone. After the decomposition reaction, the volume of the volume of lime to break down before the start of limestone difference is small, since 44% of CO2 escaping from the decomposition of limestone, so the end of the decomposition reaction of the lime is highly loose solids. After (3) decomposition reaction sintering lime, green lime kiln, lime still firing if the resulting area, the lime in the CaO crystals will continue to grow, will reduce the volume of lime, so that lime sintering. (4) lime lime shrink from about 900 ℃ down to 60 ℃, its volume will be due to cold and contracted. Lime sintering, which significantly reduces the degree of activity. We should try to avoid sintering of lime. Air duct from the furnace bottom central and peripheral duct into the kiln, the kiln pressure depending on the level of effective height and limestone and anthracite size may be. The effective height of 15 ~ 20m shaft kiln, the general into the kiln of pressure (gauge pressure) is about 5 ~ 6kPa. Air volume production capacity may be overlooked by limestone calcination of lime obtained by means of a rotating kiln conical bottom feeder, the feeder blade and the star of the discharge. The material temperature should be maintained at 60 ~ 80 ℃. Exhaust gas from the top of the kiln, into the dust, exhaust gas temperature should be maintained at 120 ~ 150 ℃. The so-called modern new lime kiln technology is environmentally friendly, energy-saving features and mechanization, high degree of automation of the modern lime kiln. It is due to the use of modern technology, so it can take advantage of cheap energy, in particular, can take advantage of the original environmental pollution gas as the main energy, turning waste into treasure. This will not only be able to protect the environment, and the good it produces lime, not only the quality and low cost. To take advantage of this new technology enterprise, there will be significant economic benefits increase. This is the promotion of new technologies kiln practical significance. New environmentally friendly kiln, lime kiln green, blue sky furnace (view) provided by LUOZHUANG Kiln Ltd. Linyi City blue sky. Luozhuang District, Linyi City, blue sky Kiln Ltd. (www.lyshihuiyao.com) (www.lyshihuiyao.com) is a professional, "lime kiln, lime kiln environmental protection, energy saving vertical furnace technology development and promotion" of the company . Since its inception, we adhere to the "good faith, sound management" approach, the courage of healthy competition in the market, so that the "blue sky kilns, lime kilns blue sky, blue sky and green lime kiln" brand has a good reputation.
