Abstract
Cement manufacture has been one of the most energy intensive industries in the world. In order to produce clinker, rotary kilns are widely utilized in cement plants. This work deals with the energy analysis of a rotary kiln system working in a cement plant in Alburge Cement Plant (ACP), at Arab Union Cement Company (AUCC), Zliten city, Libya. The kiln has a capability of producing 4200 ton-clinker per day. The main objective of this study is to examine heat loss of various components of the rotary kiln system. In the present study, a Matlab program with a graphical user interface (GUI) has been used for energy auditing of ACP as a case study. The GUI inputs and outputs showed through the paper as an interface widows. Result shows that 30% of the total energy is being lost. An amount of 20.54% missed through hot flue gas, 5.25% across cooler stack, and 4.56% by kiln shell convection plus radiation
