The paper presents a proposal of the application of the entropy analysis for the theoretical research of the processes occurring during the thermodynamic transformations taking place in the waste energy recovery systems in marine Diesel power plants. In view of the low exergy of waste energy carriers in these systems it becomes significant to make a proper selection of parameters in the individual points characterising the thermodynamic transformations of the working media. The method as presented herein consists an adaptation of the methods applied in the arrangements of shore power plants to the needs of the marine power plants. This article presents basic relations allowing to determine increments in entropy in the heating steam generation system, as well as the other basic elements forming the waste energy recovery systems in marine power plants. They constitute the basis to evaluate the performance of the individual processes and to disclose the places of occurrence of the major losses and to determine the manners to minimise same. The proposed method may contribute to the reduction of labour consumption of universally applied, traditional methods of searching the effective systems of waste energy recovery in marine Diesel power plants.
