Design of Marine Diesel Engine Waste Heat Recovery System with Organic Rankine Cycle

Abstract:

Being an energy-saving project with great development potential, Organic Rankine Cycle (ORC) is becoming one of the research hotspots in recent years. However, there is little research about the waste heat recovery with Organic Rankine Cycle on ships as yet. In this paper, the marine diesel engine waste heat recovery system with Organic Rankine Cycle was designed and analyzed. Isopentane was used as working fluid in the Organic Rankine Cycle. The conditions for the system to recover marine diesel engine waste heat were given, and its schematic diagram was provided. Finally, the ORC turbine which is the most important components of the system was designed. The numerical simulations of the ORC turbine were carried out by using the CFD program. The operation performance and flow field were analyzed.
