基于SCR系统的船舶排放设计和测试

Ship emission design and test application based on selective catalytic reduction system

文章以在建MT6023饱和潜水支持船四冲程柴油机的选择性催化还原(SCR)系统为对象,研究了SCR系统降低船舶氮氧化物(NO x)排放的原理、系统组成、布置安装要求等,并总结分析了实船排放测试的要求和注意事项,为实船排放TierⅢ取证提供了重要参考。

Based on the selective catalytic reduction(SCR)system of the four-stroke diesel engine of the MT6023 saturated submersible support ship under construction,the paper studies the principle,system composition,layout and installation requirements of the SCR system to reduce the nitrogen oxides(NO x)emissions of the ship,and summarizes the requirements and precautions of the actual ship emission test are analyzed,which provides an important reference for the actual ship emission Tier Ⅲ forensics.
