### The Effects of Rotary Kiln Operating Conditions and Design

The mathematical model of heat transfer in rotary kilns can be used to help design kilns and to estimate operating parameters for the incin-eration of hazardous wastes. As such the model can help ensure safe and efficient kiln operation. For example if a given waste-contaminated soil must be heated to a high temperature for a cer-
