# heat calculation in rotary kiln

### Rotary Kilns ScienceDirect

Heat balance calculations are usually carried out when developing new rotary kiln chemical processes or when improving old ones. No thermal process would work if too much heat is released or if there is a lack of sufficient thermal energy to drive the process or to maintain the reaction temperature.
