船舶大型化对大气污染物排放的影响

Influence Vessel Enlargement on Emissions of Atmospheric Pollutants

对船舶大型化与船舶大气污染物排放量的关系进行了研究。通过对船舶行驶状态、主辅机信息、负载因子、低负载校正因子、排放因子及燃油校正因子等多要素分析,推导了船舶排放强度的计算式。选取3艘不同吨位的集装箱船进行比较,结果表明:在船舶载箱率较高时,大型船舶可以减少污染物的排放。当船舶满载时,船舶污染物单位排放达到最低。

In this paper, we studied the relationship between vessel enlargement and the emissions of atmospheric pollutants. Through analyzing such elements as the vessel navigation status, the information of the main and auxiliary engines, the load factor, the low load correction factor, emissions factor and fuel correction factor, etc., we deduced the formula for the calculation of the emissions intensity of the vessels. Then by comparing three container vessels of different tonnage, we found that the higher the packing ratio is, the less will pollutants be emitted by the large vessels.
