The paper presents an analysis of a waste heat volume that may be recovered in dual-pressure waste heat recovery systems (DPWHR) cooperating with the selected two-stroke marine diesel engine. The analysis covers four developed DPWHR systems (two of them generate saturated steam and the remaining two generate saturated and superheated steam). The heat in the exhaust gas and charge air is also included therein. The steam, generated in the DPWHR system, is employed to provide heating at a ship and to drive the turbogenerator. The analysis refers to the effect of the pressure changes of generated high-pressure and low-pressure steam, its type (saturated, superheated) on the amount of the generated steam and its enthalpy, which has a decisive impact on the turbocharger power possible to be obtained. For the purpose of the analysis, it has been assumed that the water fed to the boiler should be heated up to the saturated temperature in the charge air cooler and that all generated steam is intended for propelling purposes. The study was carried out in stable operational environment at the engine rated power at ISO ambient reference conditions.
