| Abstract:The status of waste heat recovery technology (WHR) of marine diesel engine both home and abroad is introduced. A WHR system was designed to recover the waste heat from a marine diesel engine, and the performance calculations and economical analysis were carried out. The results show that approx 12.5% engine power can be recovered through using WHR system, and the thermal efficiency of WHR system increases about 6.03%. Though using WHR system may lead to extra investment costs, but it could be paid back within 3 years. |
