摘　　要：文章针对某一中型邮轮用柴油机,结合有机朗肯循环技术设计了一套余热回收系统。根据柴油机和循环装置相关参数,研究循环流量、蒸发压力以及烟气末温等因素对循环系统输出以及效率的影响规律。研究表明,系统输出功率及效率均随流量的增加先增大后减小;随着蒸发压力的升高,系统输出和效率均不断升高;随着烟气末温的升高,系统输出功率不断减小,而循环效率基本维持不变。This article designs a set of waste heat recovery system for a medium-sized cruise ship diesel engine combined with organic Rankine cycle technology.According to the relevant parameters of diesel engine and circulation device,the influence of circulation flow,evaporation pressure and flue gas temperature on the output and efficiency of the circulation system is studied.Research shows that the output power and efficiency of the system first increase and then decrease with the increase of flow;as the evaporation pressure increases,the output and efficiency of the system continue to increase;as the end temperature of the flue gas increases,the output power of the system increases.Keep decreasing,while the cycle efficiency remains basically unchanged.
