The growing concerns about energy savings led to the development
of exergy concept. Exergy is considered as a powerful tool in
analyzing thermal systems to pinpoint the locations and magnitudes
of irreversibilities in processes based on the second law of
thermodynamics. It is important to realize that in the endeavor
to save waste energy that some of system irreversibilities cannot
be eliminated. Nevertheless, a detailed study of the system and
its components in the light of the second law of thermodynamics
helps in specifying the opportunities to save energy with high
quality. Increasing energy demand and exhaustible natural
resources make system design with minimized costs to be one of
the most challenges that faces engineers [1]. Exergoeconomic
emerged as useful tool that combines exergy analysis of the system
with economic constrains which provides information not available
through conventional thermodynamic and economic analysis
