In this paper, superheated and saturated
vapor ORCs commonly utilized as waste heat recovery systems of a marine power
plant are investigated. First, a parametric study with different organic fluids
has been carried out by applying conventional exergy and exergoeconomic
analyses to the system considered in order to identify the best possible
operating conditions and also to evaluate the findings of conventional
exergy-based analyses. Then, advanced exergy and exergoeconomic analyses have
been performed on ORCs by splitting exergy destruction rates, exergy
destruction costs and investment costs of components and overall system to
identify avoidable parts of costs and exergy destructions. Finally, decision
criteria were suggested on the selection of more appropriate system depending
on the results of the analysis.
