Study on Recovery System for Marine Diesel Engine Waste Heat

Abstract

Firstly, this paper briefly introduces the Utilization status on marine diesel engine waste heat recovery. Combined with the characteristics of waste heat caused by marine diesel engine and technology of organism Rankine cycle, the paper designs a new waste heat recovery system for marine diesel engine based on organism Rankine cycle, And through researching the changes of temperature between marine diesel engine waste heat and the system working medium, pure organism R123, R245fa or R134a are selected as system's cycle fluid because of environmentally friendly and cycle performance more appropriate. The system application of economy on the ship are analyzed in the theoretical calculation.
