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 turbog...
