Heat Balance Analysis in Cement Rotary Kiln

principle of heat balance may be easily transferred to another system such as preheater, cooler, and drying system. Therefore the use of this study can be extended to another system than cement kiln [3]. Various reasons or circumstances may cause a need for a heat balance measurement. The following situations may justify a heat balance: 1.
