Understanding the composition and thermal behaviour of


further burn the incompletely calcined fines pro- duced by other kilns. Their circular hearths have stationary beds of lime that are exposed to mul- tiple burners which are usually gas-fired. The lime is usually carried in a thin layer; one rev- olution through the many burners constitutes a calcining cycle.
