Rotary Kilns ScienceDirect

In most rotary kiln process applications, the objective is to drive the specific bed reactions, which, for either kinetic or thermodynamic reasons, often require bed temperatures that (for example, in cement kilns) may approach as high as 2000 K. For direct fired kilns, the energy necessary to raise the bed temperature to the level required for ...
