摘要
为满足IMO Tier III等严格的船用柴油机排放法规,有必要采用机外净化技术。在这一背景下,介绍了选择性催化还原、低温等离子体辅助催化、NOx吸附催化、废热回收等适用于船用柴油机的NOx排放机外净化技术,着重论述了各技术措施降低NOx排放的净化原理与效率、相关装置运行的条件和对船舶动力系统经济性的影响。
To meet the strict marine diesel engine emission requirements IMO TierⅢ, out of engine cleaning technology has to be employed. Based on this background, Selective Catalytic Reduction, Plasma Assisted Catalytic Reduction, NOx Adsorber Catalyst and Waste Heat Recovery technologies are introduced. The discussion emphasis relies on cleaning principle and effcieney, operation condition of relative equipments, as well as its influence on the economy of marine power system.
