Performances Optimization and Comparison of Two Organic Rankine Cycles for Cogeneration in the Cement Plant

In this paper, the potential application of an organic Rankine cycle (ORC) for cogeneration in a cement plant is presented. Two ORC system configurations are considered. The first configuration is based on the waste heat recovery from the exit gases of clinker burning system. An additional heat source which is the solar energy was used for the second configuration. Parametric studies are performed for the systems with three different working fluids. Both systems are optimized from the viewpoints of thermodynamic, exergoeconomic, and exergoenvironmental analyses.
