摘　　要：针对以动力涡轮和蒸汽涡轮作为动力设备的船舶余热回收系统,分析余热回收系统对降低燃油成本、减少CO_(2)排放和船舶能效设计指数的影响。文章分析了船舶余热回收系统的原理与结构组成,以及系统性能和余热回收效果,分析结果表明:船舶加装余热回收系统(WHRS)可降低燃油成本,节省燃油4%~11%;除节省燃油之外,WHRS还大大降低了CO_(2)、NO_(X)、SO_(X)和颗粒物的排放,同时WHRS也降低了船舶的能效指数(EEDI)。Aiming at the ship waste heat recovery system with power turbine and steam turbine as power equipment, the influence of waste heat recovery system on reducing fuel cost, reducing CO_(2) emission and ship energy efficiency design index is analyzed. The principle and structural composition of the ship waste heat recovery system are analyzed, as well as the system performance and waste heat recovery effect. The analysis results show that the installation of waste heat recovery system(WHRs) on ships can reduce the fuel cost and save fuel by 4%~11%. In addition to saving fuel, WHRs also greatly reduces the emissions of CO_(2), NO_(X), SO_(X) and particulate matter. At the same time, WHRs reduces the ship’s energy efficiency index(EEDI).
