Refractory materials for cement kiln:
What is the impact of high energy saving requirements of cement kiln on refractory materials?
The preheater and the chiller system have a large surface area and are the main body of the heat loss of the precalciner kiln surface. In order to reduce energy consumption, a variety of insulation materials and refractory materials must be used to form a composite lining to reduce the surface temperature of the equipment.
Because of the high internal temperature and large surface area, the rotary kiln body is the area with the most heat loss in the cement kiln. In order to reduce energy consumption during operation, it is necessary to try to reduce the temperature of the kiln cylinder. This requires that the refractory material of the cement kiln firing zone has good performance of sticking kiln skin, and the kiln skin protection can greatly reduce the surface temperature of the cement kiln firing zone. For the decomposition zone and the transition zone, a high-quality refractory material with a lower thermal conductivity should be used to reduce the surface temperature of the outer cylinder.
