<p>Limestone will decompose under certain conditions of temperature, so temperature fluctuations will directly affect the quality of the product. Three important major temperatures are calcination temperature of active lime kiln, temperature in kiln tail, and temperature of secondary air and preheater outlet, and temperature once established for those regions or media should be strived to preserve. But because of the lime kiln is with a variety of relevant factors, so temperature cannot be set.</p><p>Rotary kilns are a critical component in manufacturing of cement, lime and mineral products. With over 35 years of experience servicing these industries, A-C Equipment plays a critical part in the ongoing design, fabrication and repair of these rotary kiln installations. From the complete design of a new kiln system to process auditing and on-site operator training you can count on A-C equipment as a partner in keeping your operations up and running.</p><p>In actual production process, the kiln fluctuation of fuel calorific value in the lime rotary has great effect on temperature system. Small range and short time fluctuations can maintain the parameter like constants and fuel volume of lime rotary kiln system, but for temperature fluctuations with large range, production and fuel volume should be adjusted to maintain normal temperature system of lime kiln. Changing the yield or fuel quantity depends on expected fluctuations time of kiln temperature.</p><p>Lime <a href="http://www.ft-productionline.com/proitem/p12.html">rotary kiln</a> is in open work, system from the ambient temperature is reflected in extreme weather conditions such as rain, snow, and lime kiln temperature will probably decline if ambient temperature declines, so it’s need to add a small amount of fuel to cover the above-mentioned changes. It can be seen from the production time that temperature control is mainly in two points of kiln tail temperature and kiln flame temperature, respectively in around 950-1000 °C and 1350 °C.</p><p>desulfurization gypsum dryer: http://www.fut-china.com/p-24.html</p>
