摘要
介绍了国内外船舶柴油机余热利用技术研究现状;设计了柴油机余热利用系统,并对系统的性能和经济性进行了计算和分析。结果表明,该余热利用系统可回收相当于主机功率12.5%的电能,余热利用系统热效率提高6.03%,虽然增加了投资成本,但可在三年内收回。
The status of waste heat recovery technology （WHR） of marine diesel engine both home andabroad 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.
