Rotary kiln burning zone temperature is low because of high temperature and improvement measures
Yesterday, details of the rotary kiln burning zone and lower ends of the temperature causes and improvement measures today to explain in detail the rotary kiln with a low temperature, high temperature kiln causes and improvement measures. First talk about the performance of this phenomenon: black attempting long flame has long, kiln temperature is higher than normal temperatures, wet kilns with a chain of materials, high temperature, moisture smaller. "Kiln skin" and the material temperature is below normal temperature. Kiln firing zone material is brought up the height of the lower wall, clinker particle size is small, loose structure, low weight liters of free lime is high. The ESP load large, multi-Wei Liang, no chimney flying the ESP device is increased. The formation of such a low firing temperature, high temperature kiln reasons: excessive ventilation, the elongated flame, the flame temperature section away from the kiln, poor-quality coal, ash content, fineness thick, large water , the combustion speed is slow, so that the flame stretched. Rotary kiln with a low temperature, high temperature kiln treatment: Proper off small ventilation, reduce the flame to reduce kiln temperature. Improve primary air volume, reduce coal fineness, reduce coal moisture, accelerate coal combustion speed, improve burning zone temperature. Adjust the air wing angle, increasing wind coal blending and coal injection pipe to the kiln moves to strengthen a secondary air mixing and improve coal combustion speed, shorten black attempting.
