  • Waste heat utilization technology of lime kiln LCDRI CN

    Waste heat utilization technology of lime kiln LCDRI CN

    Jun 10, 2019 The physical heat of the lime from the kiln is determined by the lime cooling system of the kiln. If the cooling effect is good, the temperature of the lime from the kiln is low, and more heat is brought into the kiln again by the cooling air to participate in combustion. Therefore, the structure of cooling belt or cooling device of lime kiln plays an important role in the utilization of waste heat of lime from kiln.
