Abstract

This paper presents ENERGY and EXERGY analysis of the power generation system of a 2700 kW MARINE DIESEL ENGINE. The power generation system is consisted of diesel engine, turbocharger, high and low temperature water cooling system, and heat exchangers. Compressed air is passed through the compressor and is cooled using an intercooler by high and low temperature cooling system. In addition, oil temperature is lowered in the oil heat exchanger via the low temperature cooling system.Implementation of EXERGY analysis leads to identifying critical points with maximum entropy generation. Outcomes of this research can be used in order to improve performance characteristics of the system. Obtained results showed that the EXERGY destruction in diesel engine is 41.9% of inlet fuel’s EXERGY and 86.9% of the total EXERGY of the system. Although 18% of heat dissipation occurs at the intercooler and oil heat exchanger, they waste less than 1.8% of inlet fuel’s EXERGY. While the turbocharger plays no role in the ENERGY balance of the system, it dissipates 4.5% of inlet fuel’s EXERGY.
