摘要: Abstract Stricter rules and regulations about emissions for marine vessels escalating fuel prices have motivated researchers engineers to study further on improving efficiency. Thus, it has become crucial estimate the improvement potential sources of irreversibilities within energy systems. In this paper conventional advanced exergy analyses are applied a steam power plant reveal insights which may help designers make decisions component renewal issues. The results showed that highest destruction is boiler due chemical reactions. Moreover, avoidable destruction. Pumps in system contribute small percentages. Turbines more importance compared heat exchangers. findings endogenous destructions indicated efforts should be focused essentially boiler, turbines, condenser pump equipment respectively, feed water heaters could improved externally by other components. It also concluded overall 10% efficiency, almost three out four two components namely, (6%), low pressure turbine (1.3%), smaller room improvement.
