摘要

In this study, exergetic efficiency of Turkish cement production and CO_2 emissions caused by the sector due to exergetic losses and environmental effects are examined, considering the clinker production between 1999 and 2007. As a first step, exergy analyses based on dead state temperature and production data of clinker are carried out according to the second law of thermodynamics. Consequently, CO_2 emissions of the clinker production according to exergy losses, improvement and anergy potentials are determined. Exergy efficiency of the kiln and exergetic improvement potential are found as 43.04% and 123.29×10~6 GJ/h respectively on average. In this system, CO_2 emissions caused by exergetic losses are calculated as 75.18×10~6kg/h, 25.06×10~6 kg/hand 81.45×10~6kg/h respectively on average for the coal mixture, natural gas and fuel-oil. At the end of the study, the present technique is suggested as a useful tool to improve energy policies and provide energy conservation measures, especially in this type of industrial processes.
