The efficient use of waste energy is a major element in designing the energy-saving marine power plants. The ecological aspects of the usage of this energy are of importance as well. Thus the need to perform the evaluation becomes significant – in respect of both the sources of the waste energy and the marine systems of its recovery, inter alia in terms the achievable efficiency levels. Besides the determination of the available quantity of the energy it is necessary to take into account the value characterising this energy in terms of its quality. The measure of the quality of the energy is the value of the maximum capacity of work performance referred to as the exergy. The exergetic analysis allows to determine the values of the individual jets of working media as well as, which is particularly important, allows to properly assess the proportions of losses in the individual elements of the recovery systems under investigation. Therefore it is a basis to calculate their exergetic efficiency. The article presents the balance values of the energy fluxes of the selected ship’s main propulsion engines as well as, inter alia an example of the course of the changes in the specific exergy and enthalpy of the exhaust gases in the function of the load of ship’s main propulsion engine. It presents also the examples of the exergetic analysis of the main propulsion engine exhaust gases recovery systems with the application of Brayton cycle, Clausius-Rankine cycle or both cycles combined.
