'ROTARY KILN Fig. 2 Mechanism of heat transfer in a Rotary Kiln In a rotary kiln, the charge normally occu-pies a small area and a large area of refractory wall is exposed to the flame or hot gases (Fig. 1). Due to the rotation of the kiln, the heated re-fractory lining gets covered with the charge leading to substantial heat transfer by condu-

Third, the cause analysis of fire damage and countermeasures. 1. Mechanical stress damage. (1) Thermal expansion squeezing refractory bricks. When the temperature of the kiln rises to a certain extent, the thermal expansion will generate pressure in the axial direction of the kiln, causing the adjacent refractory bricks to squeeze each other.

The refractory in a direct-fired rotary kiln is a crucial component, serving to both protect the shell of the drum and combustion chamber from the high interior temperatures, and to minimize heat loss. As a result, protecting refractory is not only critical to promoting optimal efficiency, but also to maintaining and prolonging the life of a rotary kiln.
